I posted a week or so ago and have since better understood my
limitations.
I want to have one source in my home for audio and home theater (HT).
I want the following:
a) HT setup in family room (location for all componentry)
b) audio in kitchen/dining
c) audio in master bedroom
d) audio outside
The twist is that I am interested in higher-end audio than one might
expect with a whole-house setup - with nice speakers in all locations.
These speakers will vary in maker, size and type and will be selected
for the room or location. For instance, I may have Magnepan MGMC1's in
the kitchen/dining (maybe even a subwoofer) and Axiom bookshelfs in
the master bedroom, etc.
I was thinking a high-quality 12 channel amp to power everything with
5 channels going to the HT and 6 others going to the other 3 pairs.
These would only require a total of 2 zones (HT for one, audio for the
second) from a nice preamp. Another thought is to use a 5-channel A/V
receiver for the HT and another amp for the other areas. I originally
considered a 7 channel amp using 5 of those for the HT and the other 2
from the 2nd zone outputs into a speaker selection (switching) box for
the other 3 pairs since using them all at once isn't a primary
requirement.
Unfortunately, I can't find any good info on how good these amps are
compared to higher end 2-channel amps (use B&K for comparison) or
whether their high prices are based on the fact they are normally
considered commercial products. I've been looking at the Niles SI-1260
specifically. In fact, I have real concerns that the real different
requirements based on the speakers for each room will require the
ability to adjust EQ settings for each pair separately yet it doesn't
appear that these multi-channel amps have that flexibility. In
speaking with a tech at Niles, this is an unusual request and not
something they provide for (for a $2500 amp!). This is odd to me. I
was originally thinking that a multi-channel amp would allow me the
most flexibility from all accounts.
Rather than make this into a book, I'll stop here to see what comments
I get, if any.
Thank you for taking the time to read this and any response you may
have.

I wouldn't go so far as to say "you get what you pay for", but you have to
be cunning.
Rather than take advice wholesale from people with different ears, I suggest
building a two channel system first. When you finally get it to sound right,
you'll have an inhouse standard for comparison.

Denon's higher-end amplifiers have a multi-room feature. This takes
care of the master bedroom/AV system and kitchen/dining(aux). Or
the reverse. It uses two of the rear channels to drive the other
room. You can select multiple inputs and options.
Your only other option is to get a dedicated system for each room.
That means a master amplifier and a line-level splitter. Denon
makes these as do others, all the way up to McIntosh.
You then get a 50wpc 4ohm amplifier or pair of small monoblocks for
each room. Hide these where you can.
I personally like Denon's system as it has remote transmiters and
controls for each room. Your main amplifier sends the line-level signal
to the splitter. Then it goes to each room, which has its own remote.
You will need a remote amplifier in each room, but that's simple. I would
suggest the main system and outside be together. Outside only needs 2
channels anyways, and they can be 8 ohm ones at that. Mirage makes the best
outdoor speakers that I know of, BTW.
The DRA 685 will do all tree rooms in fact - the kitchen will need a seperate
amplifier, but that's easy to do. You can also add a supplimentary amp for
the main room. $499 plus some boxes and remotes.
In general, current capacity seems to go down as you add channels, due to
increasing sizes of transformers and storage capacitors required, so I
personally beleive there's usually a trade off. The maximum you can get
off a house hold outlet is 1500 Watts. Divide by two for the usual
inneficiencies in a class A/B amplifier, and you have 700 Watts. Divide
this by twelve... and you have less than 70 watts per channel. If this is
all you want, and I can see that for the outside and casual listening, then
you're golden. But for the home theater and Magnepans, you'll really need
more.
If you have the space, I'd buy amplifiers with no more than 2 channels /
unit. Also, consider the idle power and just how much electrical power
you're going to need for all these outlets. You may need an extra circuit
run.
As for equalization, exactly what are you planning on equalizing, and how
are you going to calibrate it?

OK, so the response might be 0.5 dB down at 20 KHz. The audible

Presuming that amplifiers are equalizers, which the good ones aren't.

As far as you've gone thusfar Morien, you might as well add any other
unfounded generalities that might fly into your head.

Now, that might not be a bad idea. Start out simple and work up into
multichannel, which is more complex.
And depending on the room, the quality of amp can be compromised.
You won't have lots of volume in the kitchen, and it's all reflective
surfaces anyway. The bedroom (mine at least) is very absorbant - big
bed and a rug that sucks up a lot of the high and mid.
My living room is very bright sounding (glass doors, hardwood floor, not
so much cushioned furniture, etc).
Can the 12 channel amps handle volumes/room? PreIn/Out per room? (I've
got a Stereo Pro 31band/channel EQ in my main room because I owned it
before and occasionally will slide in a compressor/limiter for the
occasionally annoying TV/Movie that had excessive ranges (Jurassic Park
jumps to mind with 65db talking and 100db monster roars).
Once I feel I understand the logistics, I'll start matching up the
componentry under real conditions as was suggested... very good
advice. It starting to appear that a do-all amp isn't going to cut it
and I like the idea of slave amps (if that's the right terminology)
dedicated for each vastly different speaker arrangement. I really need
to educate myself on exactly how that would work now...

I'm actually referring to simple EQ like bass and treble settings for
each room and I don't think there are any pre-amps out there that
handle settings for more than ~7 channels at this time... right? So
how do I go about making adjustments like that for multiple rooms
driven by one master?
Sorry if I sound somewhat ignorant. Today I am. Next week hopefully
less so! :)
Thanks again,

We USUALLY find audible differences, sometimes large, sometimes small.
We usually have strong preferences as to which amplifier we prefer, and it
typically varies, depending upon whether the speaker has a hard dome or soft
dome tweeter.
About ten days ago, we compared a Yamaha DSP-A1 to a Hafler SE-240, and,
in a separate comparison, a Hafler XL-600 to a Coda.
Our preferences were unanimous and strong: we preferred the SE-240, as
well as another basic amp, to the DSP-A1, and the XL-600 to the Coda. The
results of both these comparisons were economically and egonometrically
inconvenient to my friend, who will now change his setups as a result.
To continue this discussion, I prefer to replace the word "good" with
"perfect", because "perfect" has mathematical meaning, as in f(s) = 1, where
f is the transfer function.
I would agree with a position which states "All perfect amplifiers sound
the same." However, as there is no perfect amplifier, they may or may not be
distinguishable or preferable. As there is no perfect speaker, faults of
amplifiers and speakers may cancel or reinforce to produce a particular
psychoacoustic effect.
There are many individuals, both in print and on this newsgroup, who
propagate various beliefs as the absolute truth. I am not aware of any who
have both published in peer reviewed journals, and had their methods, IN ALL
THEIR DETAIL, NOT GENERAL PROPOSITION, adopted as standard methods of
investigation for audio. If you will consider the above statement for a
moment, it acknowledges that some of your techniques may be standard
practice, but have not been accepted in ensemble as a complete experimental
procedure by researchers in the field of high fidelity amplification.
It may be that to a large percentage of the population, a receiver
will produce adequate sound. Of course, as I run the danger of falling into
the trap of proclaiming infallibility, the roadmap which I propose for
Randogbert has one advantage: If he follows it, he can reach his own
conclusions, as they apply to his ears. A personal conclusion on this
subject is far more valuable to him than an academic one.
I had a B&K amplifier and discarded it. I found the amp to be dark,
soft, and unrevealing.
I looked at the Niles web site. I suggest their 12 channel Preamplifier
(not the receiver) as it has the tone controls you are looking for. Add to
that your choices of external amplifiers, and you'll pretty much get the
whole house wired.
Also, if you're going to go that route, I'd keep the home theater system as
separate as possible. Keep it simple, and in it's own space. This will
give you maximum flexibility.
Another possibility is a combination. Start with something like the Lexicon
MC-12 which gives you 3 zones, you can use one zone for your whole house,
and have 2 A/V zones. This way you can have 2 rooms with sound and movie
capability. It depends on wether you wish to have many multiple areas which
can be independently selected, or wether you want 1 source going to your
entire house.
Take care,
ERik

They also make a separate 12 channel preamp that gives whole house control,
separate sources/control per room, etc. This makes a better option
depending on how serious you wish to EQ each room.
It seems like a bit of overkill for my tastes.
I have the Behringer DSP EQ, built in limiter, in addition to Midi control.
Very sweet unit, if I had the money I'd buy 3 for my home theater.

Keep up the good, if not perfect, work.

The Voice Behind the Curtain:
Morien, your listening evaluations no doubt failed to be
level-matched, time-synchronized, and/or blind. End of story!
If I do listening tests that aren't level-matched, time-synchronized,
and blind I can *hear* differences between any two pieces of audio
gear that have ever existed or will ever exist, even if they are
exactly identical.
Morien, by now you should know this line, chapter and verse. How many
times does this have to be explained to you before you will
understand what it means?
No, this is a discussion about fairly gross differences.
> Arny is an advocate of an experimental protocol.
No, I am an advocate of using appropriate experimental protocols for
the purpose at hand.

In the case of the need for listening tests that are blind,
level-matched, and time-synchronized it really doesn't take a lot of
formal and/or mathematical reasoning.
The simple fact is that if a listening test is not level-matched,
time-synchronized AND blind, just about anybody can *hear*
differences between any two pieces of audio gear that have ever
existed or will ever exist - even if they are absolutely identical.
How simple does it have to be?
> I'm using the customary language for the purpose.
No Morien, you are just posturing the usual postures that we see from
people who for some odd reason have missed something that is really
quite obvious.
> A lot of people have made ad hominem attacks on Arny. Justified

Good for you! But, it doesn't help the abject naiveté and
incorrectness of your purported listening tests.
I differ with you not on the usefulness of blind comparisons, but on the
finer points of your protocol. Put simply, I feel you take a good idea and
implement it badly.
> > I'm using the customary language for the purpose.

Regardless of whether my listening tests are valid, even for personal use,
my errors cannot validate your protocol. That has to be done by
appropriately credentialed third parties who have examined your protocol in
exquisite detail, and permitted you to publish in refereed journals. Failing
that, there has to be some evidence of use of your protocols by the hifi
industry at large.
As with any other individual who promotes a specific protocol, the
validation of that protocol cannot come from the experimenter himself.
You can't prove yourself right by proving me wrong.

Simply put Morien, nothing's perfect but my "implement(ed) badly"
protocol is about 24 years (more or less) ahead of where you are
right now.

Your publication list is not valueless.
I don't dispute that some of your ideas are sound.
However, there is no evidence that you string the individual pieces together
in a coherent fashion.
It's BAD SCIENCE, BADLY IMPLEMENTED.

Wow, what a grandiose statement. How many of those papers have you
read, Moerien? I'm guessing the number is real close to zero.

That's a nice change of pace. But you will get back off track quickly
enough, Morien.

Horsefeathers.
It's such a simple idea.
You just match the levels,
synchronize the music in the time domain,
and oblige the listener to make his judgments by just listening.
How can such a simple thing be anything but coherent?
> It's BAD SCIENCE, BADLY IMPLEMENTED.
Prove it.
BTW, what the hell do you call what you do, Morien? It's not even bad
science, it's like no science at all. But yet you base technical
judgments, grandiose claims, and purchase decisions on it. Why?
You are an obviously talented engineer who in my opinion, simply allows
personal bias to contaminate his work. If I were to weigh your work, my
guess is I'd find 80% of it to be of good quality. Unfortunately, in the
remainder, you allow bias to intrude, and the quality is not there.
It's tragic, because the result is a waste of your obvious talent.
I think the best path would be for you to soften your strident tone, and
recruit some persons with standing in the industry to jointly conduct
experiments with you. Ideally, these should not be individuals who
absolutely agree with you, but appear to be open-minded. You should go into
this with the the willingness change your beliefs, if the results justify
it.
In terms of the number of logical steps which you apply to reach your
conclusion, you are not so far from the truth. But in my opinion, those
steps which are in question are so crucial that the outcome is considerably
changed.
I once tried to get you together with John Atkinson, and learned from both
of you that there are irreconciable differences. But there are many other
excelllent candidates.
Why don't you try putting out a feeler to Sidney Harmon? Explain what you
want to do, see if there's anyone working in his organization who would want
to participate. Another good guy you could work with is Jim Johnston, who I
believe is no longer at Lucent.
One should not belong to an idea -- it's better if the idea belongs to you.

Why not just put independent audio systems in all the rooms? If you
want a central music library, why not use a central file server with
small PCs as audio servers, or the MP3 network appliances sold for
the purpose. We're talking $300-600 per station here.

If you want a good example of a truly commercial multichannel
amplifier, consider the Rane MA-6. 100 wpc x 6. List List Price:
$1649.00 Street Price: $1249.00 Compare this to the B&K 125.7, a
slightly beefier amp with one more channel. List price $1795 Street
price $1495. These prices may seem high until you realize what you
are getting - at least 3 each 100 to 125 wpc power amps at a price of
about $400-500 each. IME $400-500 the going price for better-quality
2-channel power amps in the 100-125 wpc power category. I've got
several of 'em.
It's begs the question - why not just buy 3 100-125 wpc power amps,
say some comparable Haflers. Well, if space is an issue...
It also begs the question that if what you want is a bunch of
2-channel systems, why not trot down to Best Buy or Circuit City and
pick up some what Sony or Onkyo 100 wpc receivers for under $200 a
piece. That HT system would be 5.1, but again you can get 100 wpc
5.1 receivers for under $200 a piece. Where do these ultra-low prices
come from? Very specific, kinda inflexible solutions from the mass
market.
Could you hear the difference between any of these alternatives in a
DBT? I doubt it. What you are buying is flexibility and packaging.
You are also buying the ability to easily introduce advanced concepts
like relatively precise equalization. You also won't have to purchase
a whole receiver electronics package if you decide to upgrade the
number of channels in that HT system, for example. But, the economics
for a simple solution are pretty compelling.

Well, if you are talking Commercial audio, the logical complement for
the Rane MA-6 would be a trio of Rane ME-60s or GE-60s or a sextet of
Rane PE-15s. The ME-60s would run you about $550, the GE-60s about
$650 each, while in comparison pairs of PE-15s would run you $600.
I've got several of 'em.

No, but I can and have proven that you're wrong by proving that I'm

A very ironic statement given that the core of my work is
bias-controlled listening tests. Yes, I've got a bias - against bias.

What you don't and can't know until you've been there Morien, is what
it means to have done bias-controlled listening tests for say 20+
years. Much of the world of audio still looks pretty strange when you
know what's bias and what's real.

Been there done that. Maybe you want to visit www.pcabx.com? If you
read and understand just the home page, and realize what the cosmic
meaning of the FACTS there are, you might think differently.
What's going on at PCABX is that for the past 3+ years literally
10,000's of people have been introduced to bias-controlled listening
tests by means of personal experience. I watch the comparators get
downloaded and I watch the test files get downloaded and I just
marvel that there is still so much interest and activity.
Obviously, www.pcabx.com is over a lot of people's heads, but both
the basic technique and the basic concept are catching on with the
general public, still a bit slowly. I stopped doing much development
of this site over a year ago because I realized how far ahead it was
of its audience. One of these days I may have to start seriously
developing it again... Meanwhile I'm, waiting for most of the
consumer world to catch up.

Morien you really don't understand what is going on, and how long it
has been going on. You obviously have zero familiarity with the
literature I cited which is only a fraction of what I could cite.
Morien, you don't seem to appreciate that there are entire
billion-dollar corporations, specific examples Ford and Harman
(please note the spelling of Harman), where the gold standard for all
important decisions involving listening, is level-matched,
time-synched DBTs.
Morien, you don't understand that I'm not about results, I'm about
methodologies, and the plural is real and meaningful.

like this: "DBTs are great in their place which is not for me. I'm

For one thing Atkinson is a talented liar and artful deceiver who has

of people back on the path to the truth. It's dirty work but someone
had to do it.

That happened over the past 10-20 years. The guys who got to Sidney
Harman were Toole and Olive. The deed is done, Harman is on board.
You really ought to check the references I gave you - the Toole and
Olive references are a thumbnail sketch of the DBT-ization of Harman.

This idea is way to big to belong to one person, and it has been for

The biggest difference is that the Rane gear has balanced I/O which

I own the "ears be the judge" concession at RAO. Long, sad history
has shown that my critics can't hear differences worth squat unless
they peek.
If the listening evaluation is not blind, is not level-matched,
and/or is not time-synched I can reliably perceive a difference
between any two audio components that have ever been made or will
ever be made, no matter how identical they are. Prove me wrong!

Randy,
I had a similar need and use Magneplanars both for the main speakers
(MG-1.5/QR's) and remotes (SMG's).The main Magneplanar are conventionally
powered by an ADCOM 5400 which handles the current requirements of the
Maggies nicely.
The solution for me for the remote speakers was to buy separate, used ADCOM
GSA-560/GSP-700's at eBay for ~$100+. Each of these provide three channels
(1x80/100 watt + 2x40/50 watt) with IR-based volume and input remote
control. The GSP-700 also switches video. They were designed as add-on's
for cheezy multi-channel audio strategies and are dumped cheep. You can
safely disregard the surround-sound functions and use them as high-quality,
amps with IR-controlled input and volume. The IR can be remotely routed (I
use a Nirvis Slinke) and is more easily integrated with home automation
controllers than most/many proprietary systems.
(FWIW, I have the pcbs, components, chassis, xfrms and heat sinks for 16
(sixteen) channels of Nelson Pass 40 watt Class A amps that are excess to
my needs that I'd be pleased as punch to pass on to someone at a bargain
price. 640 watt heater anyone?)

Arny is no audio engineer. At best, he is a technician. The Armed

in that they made him "the best that he can be", which ain't much.
Ohm
Of course, this is just a subset of my resume.
Sockpuppet Yustabe, by what authority do you claim to be qualified to
evaluate whether or not I'm an audio engineer?

Who said anything about PA amplifiers?
It is true that some people use high quality amplifiers for P.A.
systems. Does this necessarily make any amplifier that is ever used
for such a purpose a "P.A. Amplifier"?
What's cool about that is maximum flexibility. I would still need
volume controls between the amps and the speakers, but that's no big
deal. I'm still not sure how to add subwoofers into the separate zones
should I decide to, or if I'll need any type of other EQ controls...
any comments here?
Also, the Niles preamp you mentioned has some nice features but is
missing others. Here's where I really show my ignorance... can more
than one preamp be used in a system like this? I.E: A/V preamp Zone 2
out to Niles multi-channel preamp out to separate amps? Probably
wouldn't do that since the Niles preamp is really much more complex
than I need with most features going unused, but for general knowledge
it would be nice to know. Remember, the whole goal here is to use one
platform where all the source components reside (CD, DVD, tuner, etc)
and be able to have them ported to different locations with quality
sound.
I appreciate the comments. That said, please don't use this thread for
bashing... it's all good.
Thanks,

Unbalanced lines are extremely susceptible to all kinds of effects. You
can't fix it by using good cable or positioning the lines. The way the house
is wired for power has an effect, and even putting everything on the same
branch won't fix it.
You have been asked numerous time to post to RAO your qualifications
as an audio engineer and you have failed to do so.
After the U.N. is done looking for hidden WMP programs in Iraq, we'll
send them to your house to try to find out where you are hiding
your so called qualifications.
I concur with both of the above remarks.

I've sampled an older Bryston amp. While the build quality was impressive, I
was not impressed with the sound of this low bias amp. Perhaps the newer
ones sound better?
I have very strong preferences regarding amplifiers. So I think it's
important for Randogbert to choose carefully, or at least to try to choose
carefully. If he then determines that variations in this component do not
interest him, he is then free to pick based upon ergonometrics and
practicality.
I just think it's a shame to buy 12 channels of anything, and then discover
one really prefers the sound of high bias MOSFETs, Transnova amps, bipolar
Class-A-to-35-watts, etc.

As opposed to arm-waiving, badly implimented?
Give him some credit. He puts in many hours trying to actually
apply some science to audio. His audio card test page is a great
resource that I point people to all the time - because his observations
tend to mirror what I and many others have found.
If he's getting this right, then his methods and science are
likely correct. What he does with the data and the conclusions he
draws from it... well, we are all free to argue on that. :)
Just get a normal A/V amplifier and run it in stereo mode. Run the
line-levels from the source into the main amp, bypassing the amp's
own preamp. You get a remote control and all the goodies in each
room, plus subwoofer output and such.
Most typical consumer amplifiers will drive Maggies well enough in
two channel mode. Denon, HK, NAD, Onkyo, and simmilar models are
rated to drive 4 ohm speakers if only used in stereo mode.
The Denon IMO, is a perfect solution - it has a preamp out to a second
amplifier, and the rear/secondary channels can drive the outdoor speakers,
which are really not much of a load at all. The second room will have its
own amplifier, so you can either daisy-chain them together, or bypass the
main room's input altogether say if you want two different FM channels,
as it is a full-fledged receiver by itself.

If you look at the thread, everytime Morien gets cornered, he starts
raving about bad science. I take it to be as serious and significant
as Singh's rants about how bad someone's stereo is. Obviously Singh
hasn't heard the stereo and can't know, but he's trying to be as
hurtful as he can be.

One important point about www.pcabx.com is that there are no results,
test data, or conclusions posted on the site. Those are left to the
listeners to develop on their own.
It's obvious that he is very emotionally attached to the conclusions he
draws, far too much so. I would not like to entrust someone so emotional
with sole stewardship of the truth, whatever that may be.
As with persons who take a middle position on an emotional issue, my
position tends to antagonize persons on opposite poles. I do not believe
that Randogbert should, in the absence of ABX equipment, fail to trust his
ears. On the other hand, if he did in fact have ABX equipment available,
which was made well enough not to conceal differences, then he should avail
himself of it.
> If he's getting this right, then his methods and science are
> likely correct.
I strongly disagree. You are extrapolating. This is Arny's sin. Extrapolated
conclusions are of low quality.
This is how you are supposed to do it:
1. Establish the performance of a no-cost no-limititations design, using the
50 ton granite slab, the bed of mercury, the Halcro amp, the mercury wetted
relay contacts, and the extensive use of unobtanium alloy. The direct
translation of this is that Arny has to build a device using all the things
which he doesn't think matter, but concerned third parties think might.
2. Build a practical device and show that the result, ie., the level of
discrimination is the same.
Arny doesn't do this. He makes "reasonable" assumptions. There is NO SUCH
THING as a "reasonable assumption." He has the typically limited resources
of an individual. He doesn't have a Halcro amp; he doesnt even have a Hafler
XL-600. He has had one or two high-priced amps in his hands, and he
EXTRAPOLATED. He made these items stand in for the universe of high-priced
amps.
I built an ABX device. I built it out of a pile of brand new relays with
nickel-palladium contacts. It has a remote control device, it has precision
pots for level control, and it will do speaker and/or line level switching.
The device is a failure. I took it over to a friend's house, who I am
convinced hears differences which do not exist, being influenced by the
physical appearance of the unit, etc. We tried it out, and discovered that
the device was masking the differences. What I had neglected is the quality
of the relay contacts. Nickel-palladium has too much resistance. There are
rectification effects. I should have used silver-silver oxide, but they
weren't locally available.
>What he does with the data and the conclusions he
> draws from it... well, we are all free to argue on that. :)
>
I doubt Arny made such a grevious mistake, but there are multitudinous
places where hubris and extrapolation will temporarily allow logic to cross
little crevices. That's why I say Arny's work is 80% good. It's the 20% that
kills the data. Would he fairly interpret the data? I don't know. Arny has
never had a chance.
So I think Arny's talent should be coupled with that of several
collaborators with more temperate dispositions, and less fervor. People who
are more interested in finding the truth than proving a point. People with
deep pockets, so that Arny does not have to make "reasonable assumptions."
And as for my amplifiers? They are like musical instruments to me, and less
bulky than speakers. For my collection, I have picked examples of various
topologies. One type is notably absent: the bipolar class AB low bias. Many
of these amps, like the Crown DC series, the early Brystons, and Ranes, and
the early Aragons, have a sound that drives me out of the room. Naturally,
it annoys me that Arny says I should sit still and be happy, because "there
is no audible difference."
And there are plenty of amps that just...sound...the...same.

Not to sound like a broken record, use balanced I/O from some vendor
or another. Long runs of line level cables are very suseptable to hum
and signal degredation. Line Level cables are probably the best way
to connect component in less than 5m distances, however after that you
are relying on good luck that it will work properly.

I submit this as support for my belief that Arny needs collaborators to go

errors, and salvage the good 80% of his work which is unfortunately obscured

My online audio test reports are composed of far more than just the
one page that Morein claims. But how would Morein know? He doesn't do

As I will show below, Morein's beliefs are based on grievously flawed
thinking and demonstrated ignorance of highly relevant facts that

This is a classic straw man argument because I'm hardly the sole
steward of the truth when it comes to the necessity for blind testing
of power amps or other audio gear. I don't know how Morein can say
things like this, except if speaking from total ignorance.

Morein is simply wrong here. He's not taking the middle ground, he's
taking one of the two possible extreme positions.

Given that Morein just reached an extrapolated conclusion of his own
about DBTs being optional when you don't have the resources, one
really has to wonder!

Since "unobtanium" is a mythical material that is impossible to
obtain, you can interpret this statement from Morein as saying that
its impossible to do a proper blind listening test. The 50 ton
granite slab is just about as ridiculous as the unobtainium alloy.
Basically, Morein is saying that its OK for him or anybody else to do
sighted evaluations with no controls at all, but anybody who wants to
do a proper level-matched, blind, listening test of power amps has to
jump through contrived, impossible hoops that he's made up with his
own fertile imagination.
If Morein can compare two power amps WITHOUT the 50 ton granite slab,
the bed of mercury, the Halcro amp, the mercury wetted relay
contacts, and the extensive use of unobtanium alloy, why can't
someone do a relevant blind test under the same basic conditions that
he uses?

I claim that all I have to do is duplicate the actual tests that the
third parties such as Morein actually does, add level-matching,
blinding, and time synchronization (not really a problem with power
amps), and examine the consequences.

There's a hidden question here, which is "same as what"?
It is well-known that Morein's sighted evaluations aren't just about
the discrimination powers of the human ear, but also about the
discrimination powers of the human eye and the well-known ability of
the human mind to be affected by prejudice.
Therefore, it is obvious and clear that Morein's sighted evaluations
can't be used as a standard for judging the discrimination powers of
the human ear or any true listening test.
OTOH, there is a long history of scientific studies of the ability of
the human ear to hear differences. I've cited some of them in this
thread, but there are tons more that I've studied.
When you find that two power amps sound different in a blind test,
and measure the differences, they are always the same or greater than
the known abilities of the human ear to hear differences under the
same general circumstances.
Therefore, it is well-known in scientific circles that DBTs of power
amps and other audio gear have equal discriminatory powers as science
has shown that the ears have, in other circumstances that are
comparable.

Actually, I do but Morein doesn't know what I do. He's talking off
the top of his head.

Which compare favorably to the unreasonable assumptions of the kind
that I just showed, and will continue to show that Morein makes.
Remember, I've already shown that Morein's first two conditions are
thinly-disguised straw men.
>There is NO SUCH THING as a "reasonable assumption."
If that's true then Morein's first two conditions, which are
themselves based on assumptions, should be thrown out immediately. I
mean who says that a 50 ton granite slab is enough? Why not 100 tons?
Why not 1,000 tons? Morein assumed that 50 tons is enough. What about
those mercury-contact relays. Are they really good enough? Morein
assumed that they are. What Morein doesn't seem to know is that I've
eliminated the need for relays or switches of any kind in blind
tests.

What Morein doesn't seem to know is that I've eliminated the need for
any other power amp but the UUT in my straight wire bypass tests of
power amps.
Now let's look at Morein's extrapolations. Despite all the scientific
literature that I've already cited for him about the need for blind,
level-matched, time-synched tests, he's assumed that it all doesn't
apply to him or anybody else. You know there's one thing about a good
extrapolation, it starts with a solid fact. Where are Morein's solid
facts?

Morein's error here is that he imposes his personal limitations on
me. He obviously must think he's spent as much or more time and money
on DBTs than I have.
I did my homework well over 20 years ago. I built switchboxes for
years. I talked to industry experts and scoured electronic supply
stores looking for the best possible relay contacts Eventually I
found them. BTW, they weren't nickel-palladium.
BTW, I didn't build just one prototype ABX relay box. I built more
like a dozen. I built a box for switching speaker-level signals that
used silver contacts about the size of dimes. I built a box for
low-level signals with hermetically-sealed mercury contacts. I built
another box for low-level signals that used bifurcated gold-plated
contacts. I built a box that used palladium contacts. I build a box
that used ruthenium contacts. I built other boxes with other contact
materials and configurations.
Each relay box was subjected to both technical and subjective tests.
Some were excellent, some were good enough, some were almost good
enough, and some were failures.

More of Morein's questionable extrapolations based on very little
real data.
I didn't work alone. I don't work alone. ABX was a team effort. PCABX
is a team effort. The core of the ABX team was six people from
various subdisciplines of audio, but a number of outside industry
experts contributed as well.

The other people in the ABX group were so temperate that Morein
doesn't even know they exist!
David Clark (The David Clark who is an AES Fellow) is the best-known
member of the group. If you read Clark's JAES ABX paper (which Morein
obviously hasn't done) you will find my name and the names of 4
other people. This list belies Morein's claim about my not having
coworkers. Obviously Morein hasn't done his homework. When Morein can
tell us who these people are, we'll know that he's done at least a
little homework. Until we know he's speaking from near-total
ignorance.

In a previous post on this thread I gave the names of two $Billion
USD corporations that rely on DBTs for listening test evaluations.
One of them was evangelized for DBTs by our Canadian colleagues, and
the other, far larger corporation was evangelized by us. How deep do
the pockets have to be?

More baseless extrapolations. My solution to the potential problem of
power amps in listening was to develop a viable, accurate methodology
that does not involve the use of any power amps other than the UUT.
Straight wire is good.
> And there are plenty of amps that just...sound...the...same.
Right. But given the self-contradictions, the straw men, and the
grievously limited resources and research that Morein has brought
to this discussion , and the clearly demonstrated fact that he
hasn't done his homework, how would Morein know for sure?
I gave Morein a roadmap to straightening himself out earlier in this
thread. He basically dismissed it. How much further do I have to go
down his crooked road with him?

I would say, "nothing special". If I was going to buy ca. 200 wpc
rackable amps, I'd go for Mackie M1400s. You're going to hide these
away so the Mackie's fans aren't an issue. The Mackies should cost
you slightly less, they are significantly more powerful, and they
have balanced inputs. Furthermore, the Mackies have been on the
market for over 3 years and are therefore better debugged.

Within reason, yes. I looked at the Outlaw web site's users manual
and saw the nice discussion of ground loops. I don't think they put
it there for the fun of it! Balanced I/O tends to help with ground
loops. LOTS!

Of course. If you are going to drive many power amps from one source,
particularly at the end of long signal lines (say 20-50 feet or more)
you use a distribution amplifier which is a line level signal
amplifier with many buffered outputs.

I don't see the integrated mixers that one sees in the typical Bogen
amp in use.
I also note that Bogen makes some high-powered 2-channel power amps
with pretty good specs. I suppose you've done DBTs of them as well?

It's also a high quality 6-channel power amp. It's got the balanced
I/O that you like. The only real concession to sound reinforcement is
the limiters, but MacIntosh has put a similar feature on some of
their power amps.

Jezmund, this is so ironic I almost can't believe it. You are the
subjectivist and you are prone to say that listening tests are the
final arbiter.
You tell me about your personal DBT experiences with a MA-6 and I'll
tell you about mine. BTW, see if you can pick out the MA-6 in this
picture:

As usual you are fact-challenged, Morein. If you were actually even
reading this thread and comprehending it, you'd know that in terms of
MSRP and/or street pricing, the MA-6 has NO particular price
advantages over alternatives from Outlaw or B&K that have been
discussed in this thread. Unlike them, it does have balanced inputs
which *everybody* on this thread including both you and Jezmund agree
is useful in this application.
So when are you and Jezmund going to get with it and recommend
equipment that is consistent with your own technical recommendations?

Again Morein, you are abjectly fact-challenged. I told you to go read
a certain AES paper that clearly lists a few of my collaborators, one
of whom is an AES Fellow. BTW I still associate with him (and many of
the rest) frequently. I might even spend New Year's eve with his wife
and extended family. I guess you should have taken my advice and
catch up with your reading, eh?
BTW, Morein, why not name the AES Fellow that is on YOUR advisory
board?
LOL!
Hitler had lots of company too.

That's your intepretation of my words. Since it happens to be wrong, I'll
restate it:
Or, depending upon who you are in this argument, it means that you do the

persons besides yourself.

Taking your argument to the absurb conclusion, does it say that Randogbert

Somehow, I assumed that the above statement would be interpreted, not

As Arny has himself noted, he does not draw conclusions on his
comparison websites - he presents the available data and lets the
reader get on with it himself.
"LOL"
I'd explain why this is just another massive rationalization, but Mr.
Krueger is too much of a blockhead to understand.
Like Krell of course.
This is bullshit of course. His sound card lists are ordered from Best
to Worse with some soundcards not even getting any kind of
endorsement, as they fall below the line that reads: "The cards above
this Black line have performance that many find acceptable, at least
for casual listening". In fact, he is now touting a single sound card
as superior to all others, in a category all of its own.
Nice try though.
At other times, you have hewed to the line that all amps sound the same.
You cannot have it both ways.
In this discussion, I have borrowed Jezmund Von Brundt's opinion of the
Rane.
There is a tendency, in flame-fests such as this, to get bogged down.
I rather like the concept of ABX. However, digitizing samples and subsequent
presentation through a PC sound card is AT BEST, a questionable assumption.
I think it's probably crap.
If I had an ABX setup personally available to me, so that I could test an
amp on the speakers I use, I would use it gladly. I would say a glad goodbye
to all the subjectivist contamination of the appearance of the equipment,
the thickness and finish of it's front panel, the shape of it's heatsinks,
and the pricetag.
But there are many different ways to physically implement ABX. It is not a
reasonable thing for Arny to quote the specs or measurements of the all the
parts in the system, and assume that the whole is the sum of the parts. This
is frequently untrue, because specs, being incomplete, incorrect, or
irrelevantly chosen, frequently fail to characterize the behavior of the
part in the system.
This is why complex systems, designed in the laboratory, still crash and
burn during the test phase. Mankind's development of abstract thinking has
cut misdirection to a minimum, but it by no means guarantees the qualities
of a complete system.
It cannot be assumed that the whole is the sum of the parts. That must be
proven.
In every logical system, there is a domailn of discourse.
For every physical theory, there is an area of applicability.
There is Newtonian physics, there is relativistic physics, and there's
quantum physics. Each has it's own domain.
The domain of Arny's methods has not been determined.
Arny's work is unfinished.
I don't like the way Arny has done it. Does this make me an extremist, or
unreasonable? I think not. I would do it differently. Do I have the time?
No.
Arny's system needs to be validated with resources that are unavailable to
him, both on the physical level, and with detached objectivism. Once the
domain of applicability is established, his work will have value, and he
will no longer have to occupy this small space, crowded with overanxious,
hyperemotional individuals, from which neither you, nor I, or Arny, can
completely exclude ourselves.
I forgot, you were a salesman at Lafayette when you were 16.
Sorry for the omission.
I apologize.
Contrary to popular belief, that photo is NOT of
Arny's basement. That is a photo of the
office of the chief client of his consulting
business, the dentist he keeps talking about.
You can see the pc Arny cooked up for him.

Being a teenage Lafayette sales trainee does qualify you

Good microphone cables can go 50-100ft easily, but they are shielded.
They do work, though. Balanced is better, of course, but not required
if you put an isolation brick or simmilar on both amplifiers. My father
did this and there's no hum in the kitchen - a run of about 40 ft.

Huh? I'm not trying to ignore anybody. I told you guys I was clueless

My plan is to study the many options presented, but for future

I saw such a multi-room system at the London Show a couple of years

tell you much about it, except that it used balanced connections and
small local amplifiers, with IR remote controllers.

Nope, they *do* sound the same as any other good amp - plus of course
they don't care how nasty the speaker load gets. My own KSA-50 shows
no sonic difference at all when I put a 2-ohm resistor in parallel
with my speakers (which are already a heavy 3-ohm load!).
You are of course just trolling as usual, Vile, since you know that I

I think it's of doubtful utility for such thinga as comparing amps,
but likely very good for determining thresholds of audible detection
of bit-depth, sampling rate etc.......

The subjectivist viewpoint, being what it is, does
not require such. It is merely opinion, and has no
pretensions of meeting any scientific qualifications.

But yet subjectivists use their opinions to criticize scientific
qualifications.
This is known as a "logic-tight box". Subjectivists seem to live in
this smug little world where their beliefs are unassailable because
they are just opinions, but they can assail anybody else's beliefs
without any supporting evidence or logic.

So why shouldn't you have just bought another "good amp" that would
have provided the same wattage at about 1/5th of the price that you
paid USED for your Krell? And why should anyone pay Krell's
"extortionist" new prices?
What a maroon! Can't even spell subjectivism! Where's that

You can't buy a *good* 100 watt amp new for Ł200 (the KSA-50 puts out
195 watts continuous into a 4-ohm load from 20Hz to 20kHz, so it's not
really a '50 watt' amp). Also, my Krell will provide exactly the same
sound quality into any load down to less than 1 ohm, at which load it
actually pumps out close to 600 watts /channel continuous!
Sure it's overkill for most speakers, but mine are a pretty severe
load, and having that kind of reserve capability is quite comforting
in a device which I use as a reference. Knowing what I do now, I'd
happily swap it for something equally capable but more powerful, such
as a Meridian 557, Bryston 4B-ST or Adcom 5802.
> And why should anyone pay Krell's
>"extortionist" new prices?
Beats me! :-)
BTW, I don't regard Krell prices as 'extortionate', since I'm not
aware of any cheaper amp which has the same overall performance
envelope. This is a lot more than you can say for *any* tube amp, let
alone the risible SETs!

A 70 watt Rotel RB 1050 RETAILS for $499. I'll grant that that is
actually a little more than 1/5th (more like 1/3). But that's just one
example (and you could likely get one for about $400, which brings it
a bit closer to the 1/5th figure). Kenwood had a 120w X 2 (8 ohms) amp
back in '99 for example that retailed for $450. I'm pretty sure that
they had more modest amps for even less. I'm sure that you could find
plenty of "good amps" in the 50 wpc @ 8 ohm from all of those "good
amp companies" like Yamaha (something like an M45, which you can find
used for about $150). It's a "good amp", so it should sound 'exactly"
like your Krell.
Besides, it's begging the question when you realize that the Krell is
actually probably equivalent to about $4000 in today's money (the
thing *is* about 20 years old after all). That's a heck of a lot of
money for the wattage, right? That's getting close to SET territory.
<chuckle>
So, you're saying that the Krell will provide "exactly the same sound
quality down to less than 1 ohm", eh? Even allowing for the fact that
you probably haven't done a dbt to determine this (it's likely just a
placebo effect), your implication is that other "good amps" won't have
this capability. THEREFORE, this amp sounds different than "any other
good amp".
Face it, you like the big, industrial, high-end look of the Krell.
That's what drove your decision, right? After all, I talk shortly
about an amp that will certainly outperform your rig for a lot less
(and it's got that industrial look but it doesn't have that
purposeful, big-handled, brushed chrome look).
You lose.
Again.

Or even a NAD or a 200 wpc Denon. <snigger>
Hell, you could probably find a very stable used Soundcraftsmen amp
from the same era (200 wpc/600wpc into 4 ohms) for about $300. Buy two
of them and bridge them and you've got 600 wpc into 8 ohms). I'll bet
that it works FINE into 1 ohm.

In other words, it dosn't "sound like any other good amp".
Right.

Well, it depends. Of course I wouldn't match an SET with your MLs
(that's what you've got, right)? That's just common sense.
After all is said and done, the fact that you actually posted
such an egregious spelling error, in a post railing against
another poster's spelling error, was an exemplary example
of your hypocrisy.
The best known one was the time before that was when they saved Apollo
13.
Arny is to stupid to recognize his own mistakes.
He gets clued in by emails from one of his few remaining sycophants.

No, since none of those amps will withstand being played loudly into
my 3-ohm speakers. For some with lighter speaker loads, such amps may
indeed be perfectly adequate.
BTW, the then-current Yamaha AX-570 did *not* sound the same as my
Krell, although the Audiolab 8000P and Hafler XL-600 did. I haven't
tried the Rotel RB 1050, but its bigger brother, the 1090, is an
excellent amp. Of course, we're back up the price range a bit for that
one.

Not if you consider the rated design wattage, which is 400 watts per
channel *continuous* into 1 ohm.

Yes - I've tried it.

Nope, it's quite a trivial DBT job, simply strapping 2 ohm resistors

You seem to forget the crucial pre-condition of 'below the clipping
point'.
>Face it, you like the big, industrial, high-end look of the Krell.
Nope, I wish it was half the size and a third of the weight - like a
Chord 1200C!
>That's what drove your decision, right?
Wrong. It was the only one available to me at the time, which sounded
good *and* was unperturbed by driving my Apogees. The Hafler XL-600
had way too much fan noise, otherwise that would have been my
purchase.

Vile, I've noticed that it's always losers like you and Trots who
award themselves victory - since no one else is likely to.
BTW, learn some basics before you make such silly claims - the
Soundcraftsman you mention has nothing like the low-load tolerance of
a Krell. OTOH, it *may* be a very fine amplifier, I haven't tried it
with my speakers.

The 250W Denon POA 9000 monoblocks sounded like a POS in the same DBTs
mentioned above - a big disappointment, since they'd been getting rave
reviews from the ragazine scribblers.

That statement simply displays your total ignorance of audio. Those
numbers don't stack up, and a bridged amp is the *last* thing you want
for a low impedance load.

Sure it does - up to the clipping point. That point tends to be a lot
higher for Krell amps................

Get your facts right, cretin, I use Apogee Duetta Signatures. Further,
I wouldn't match an SET amp with *anything*..........
