I've got a Sony CDP-XA7ES CD player. From what I've read it was an
extremeley good player in it's day, and still considered one of the
best cd players today. The problem with mine is that the laser has
gone, and Sony don't carry it anymore. I have found a site
www.partstore.com who carry it. It's about $160USD or so, but they
won't ship outside the US. Have found the same optical pick up on some
asian sites, but when I contacted them, they don't have it. My
questions are is the player worth repairing? Can I get some good ones
on the second hand market which is as good at a good price? And does
anyone know of another source for the optical pickup? Or an alternative
which could be used instead?
Thanks in advanced.

**ABSOLUTELY! Sony have turned out some shockers over the years, but the
XA7ES is not one of them. A superb sounding and beautifully constructed CD
player.

Probably not.

You can easily get one that is just as good new, for the
price of the laser assembly.
**I'll certainly pay the price of a laser for a non-functioning XA7ES.
They're superb CD players.

The bottom line is that build cost usually will out-your player
probably cost more to build than new ones do. While some of that may be
offset by genuine improvement, materials and processes haven't greatly
changed in-what,15 years?- so a more cheaply built unit won't last as
long. This is certainly true of VCR's-given replacement parts of
quality, you cannot buy one new as good as what was made in the first
years of front-load production. It's true of washing machines, car
engines, and many other things as well.
There's always ebay. Either a complete nice looking unit, or
a beat up one you could swap the transport out of. A problem
of what would need readjusting might come up, though. You
could transplant all the boards and transport together, or
transplant any damaged covers or trim.
In all consumer products-and many capital ones too-there is a quality
curve. The best are made at some point where they have the tech pretty
well down but the pressure to cut costs hasn't set in and there is a
desire not to monkey with the good thing. Once cost cutting sets in,
quality goes out the door because given the time value of money people
perceive that the cheaper one is "good enough" and the delta in price
can be reinvested to replace it: also, the buyer doesn't understand the
difference between the new one and the old one and so the new shiny
warranted one looks pretty good. (How many new car buyers appreciate
the difference between a well machined heavy sand cast cylinder head
and a near-net-shape lost foam one, which has virtually no excess meat
to machine and depends on an epoxy coating to keep coolant out of the
oil?)
If you cut the cost and hold up the price, you make more profit. Of
course the price comes down eventually, but as long as cost reduction
leads price fall you benefit in absolute as well as relative terms.
A lot of this is perception. When the customer perceives that the old
one was better, he gets conservative and less likely to buy, and our
economy is set up so you buy, buy, buy. You cannot buy a well made
consumer-format video cassette recorder new, as far as I know, at any
price-the well made decks are all strictly professional format. You
cannot buy a really well-made 35mm camera anymore, except the M Leica,
and that's been cheapened significantly from early ones. Although much
high end audio equipment has design flaws or is overpriced, it's the
only source of reasonably well built audio equipment suitable for home
use for the most part. (A few pro pieces are suitable for home use, but
relatively few-and much pro equipment today is really prosumer, e.g.
anything from Behringer, Alesis, Mackie, and many products of legit
American companies like Crown.) You cannot buy a portable shortwave
radio as well made as the Zenith Trans-Oceanics(although certain Sonys
and Sangeans do outperform themn in some ways).
It's a long and sad list.
About two years ago I listed on eBay a video unit that consisted of a top
quality (circa '82) Panasonic portable video camera, along with a two piece
portable video recorder. Picture quality is superb; low light sensitiviy
was as good as any Panasonic has ever made. Build quality was
excellent...this was top of the line gear that together retailed for close
to $2500 in 1980. It didn't have autofocus, but otherwise met and exceeded
in picture and sound quality any tape I have seen made in the last ten
years. I put it on eBay at $20, and with no reserve, in a ten-day auction.
I described it well (much more detailed than here). I felt sure some
aspiring film student or amateur videographer would grab it. I didn't get a
single bid.
But I won't "throw it". I simply can't bring myself to destroy perfectly
good, superbly built gear.
No Trevor, not as long as you're in Australia and I'm in
Michigan.
**Thought so. You should also factor in the following:
* The Sony XA7ES has a number of technical features which set it apart from
cheap CD players. These include:
Proper relay muting.
Decent output stage, which does not include primitive, 4558-style output
ICs.
* I've actually performed a DBT with the XA7ES and a couple of other players
(quite respectable, but not cheap ones) and the AX7ES acquitted itself very
well indeed. One of those players was the very impressive XA2ES.
Have you heard the XA7ES?

Can you please recommend some new players comparable to the XA7ES for
$200USD?
Thanks
But, of course, it will be more interesting to hear Arny explain it
himself...
I actually have a hell of a time listening to the differences in CD
players. I do believe there are good ones and bad ones. Difference is
extremely small though (to me). Which is why my cd player is always a
crap one. I picked up this XA7ES for cheap (not working) and trying to
find out if it's worth fixing. As usual, some have said yes for sure,
some have said no, don't waste your money. Having said that, if I could
get a $200USD CD player 'sounding' as good as the XA7ES, then I'm happy
to spend it. I'm not entirely convinced you can though, which is why i
asked him the question.

Have that site ship to a friend in the US, who in turn ships it
to you. Costlier (maybe not), but if you want the part...

A player as good as the XA7ES for $160 USD? Which one, praytell?

And indeed the good ones *do*, if we're talking about *listening*
tests. I have a Sony CDP-715E, one of the best-performing players Sony
ever made, although lacking the 'battleship' build of the XA7ES, I
have access to a Meridian 588, probably the finest 'high tech' SOTA CD
player on the planet, and I also own a Pioneer DV-575A 'universal'
player that cost less than the quoted price of a new laser assembly
for the XA7ES. In level-matched blind listening tests, these three
players sound identical - as any reasonable person would expect.

This would be a lie.
I have a Pioneer DV-563A which is I believe the predecessor
of Stewart's Pioneer DV-575A which is approximated by the
Pioneer DV-578A outside the UK.
Harry Lavo recommended the DV-563 to RAHE readers, so how
bad can it be? Of course, later on Harry dis-recommended it
for questioanble reasons, but consistency isn't one of
Harry's primary traits.
Sound and Vision gave the DV-563A a good review, and that
appears to be about the time the golden ears turned against
it.

Some 563s have trouble playing certain hi-rez discs due to a software
bug. There are also reports of random popping noises.
I haven't had any trouble with mine. It sounds good for dvd and sacd,
but I don't like the cd playback quality. This may just be an accident
of the few cds I've played on it.

Definately worth fixing up. It must have been used alot because XA7ES is a
non-moving laser block design and would takes decades before it start to
play up. I have and still own most of Sony CD flagship models ( X7ESD,
X77ES, X777ES, XA5ES and XA7ES ). I sold my XA7ES last year and although my
vote is for X77ES - being Sony's best work ever- but XA7ES is an great CD
player which you will have a hard time finding something better.

Sorry?
Good point.
There's an equal danger in missing an audible difference
because you expect it to not be there, as there is a danger
in falsely perceiving a difference because the listening
test was done naively.
So Eddie, what to do?
Actually, no, Arny. I never owned or auditioned the 563a. But I did
recommend the 578 immediately after it came out. I think for it's price it
is head and shoulders above it's similarly priced competition in sound
quality. Interesting that the editors of The Perfect Vision just picked it
for their lowest priced recommended system as the one to buy "if sound
quality is your primary emphasis".
However, it's value varies by format. It is a very decent CD player. It is
an exceptional DVD-A player at it's price point. And it is a mediocre SACD
player. It's main shortcoming is that it doesn't reveal ambience the way
better players do. In other words, it lacks the ultimate transparency that
better players have.
But is it as good, say as a Sony XA9000ES? No way. Even my C222ES reveals
a more natural sound and ambience on CD and SACD, and when output through my
DTI Pro/Proceed DAC combo, both stand-alone units come up short on CD.
And BTW Arny, I don't recall ever changing my opinion on this in RAHE. I
did however change my opinion on the cheapy Panasonic I had previously
brought to the group's attention. And that was in part based on poor video
performance. Perhaps you are confusing the two.
And for what it is worth, my recommendation to the group pre-dated any
written review of the 578. I bought it when shopping for a good DVD-A
player, and decided that there wasn't enought sound difference given the
uncertainty about DVD-A's future to justify the Arcam DV79, which is a
superb DVD-A machine. I bought it based on my ears. And I continue to
recommend it as a low-cost unit, no matter what mag or online review agrees
or disagrees with me (although it is always nice when a consensus builds
behind you).

Arnie's being modest. In his generosity of spirit he likes to shed his
guiding light to the far-flung corners. In other words, he wants
Aussie's to share in the good news that all components of a competent
design standard sound alike and therefore no anxiety need be expended
on their selection--just get the cheapest. This is the message of
simple benediction he spreads, and you may be sure I at least am truly
grateful for it. This is how I ended up with a Pioneer 676a that
sounds exactly like a Sony XA7ES. Will the blessings never cease
flowing to us from the good old US of A?
But you did make a positive mention of it in a post, Harry.
Thanks for showing the kind of slippery statements you will
restor to in order to avoid admitting to a possible error.

As another poster mentioned, Perfect Vision also said nice
things about the 563a in Mar./Apr. 2004.
So now Harry, you say that the 578 is good because PV said
nice things about it, but they said nice things about the
563 but you are right to disagree with them?

No Harry, your negative post about 563 said:
http://groups-beta.google.com/group/rec.audio.high-end/msg/0b453da09ffffb70
"I *do* know that the 563 had control chip problems that led
it to not being
able to read the SACD layer on many UMG hybrid disks...so a
lot of people
who liked the sound gave them up because of the hassle.
That is also why I
never even tried it."
> And for what it is worth, my recommendation to the group

So Harry this is an attempt on your part to steer attention
away from your mistakes w/r/t the 563?
This just shows that you were speaking out on a topic you
actually knew nothing at all about.

The fallacy your perceptions and thoughts are already well
known, Harry. Ditto for your brain, given how you just
scrambled facts like the dynamic range of SACD versus DVD-A,
and your prior recommendations and comments.

Silly audiophile... Sameness is for 'borgs. <G>
I think you're simply unschooled in Kroologic. Kroologic is an amalgam of
religious devotion, envy, BorgSmugSnot, and paranoia. (Of course it has nothing
whatever in common with human logic.)
To understand the Krooborg's syllogism regarding your CD player, you have to
invert the precepts of your human-style logic and make various allowances for
Mr. Shit's agenda and mental infirmities. To start with, discard the notion that
how the unit sounds has anything to do with actually connecting it to your
system and listening. Rather, to determine how a unit "performs", the Krooborg
must fantasize about being blindfolded and tormented. Well, the torment isn't a
fantasy, it's reality. But for a Normal person, fantasy is permitted in order to
attain the 'borg state of mind.
Now what happens is the slavish devotion to the "fact" that "all
properly-designed CD appliances sound the same". This is a point of 'borgma and
not subject to interpretation, argumentation, or reality. The underlying premise
is that if Arnii Krooborg can't afford to own a superior device, it is known not
to be superior. (That's Kroologic.)
So for you to ask Mr. Shit to name other CD players that are just as good as the
Sony is tantamount to asking him to admit he only earns $16,000 per year,
molests children, and pimps out his poor wife. It won't happen.

Congratulations on kicking Kroopologism. Most of the infected are too stupid to
realize they've been contaminated.
Arny, the 563 and 578 players are different players. Any comments I made on
the 563 were simply references to their general acceptance in the audiophile
community, as your post above simply reiterates. I presume that if you
could find me recommending the 563 based on my own experience you would have
done so. I did nothing but give "factual" information about that unit based
on its reputation.
When I was shopping, the 563 had just been replaced by the 578. I had
several modifiers inform me that the 578 was "inferior" to the 563. So I
didn't listen to them, since I suspected that this opinion may have been
based on a) the ease of modifying, or b) the need for modifying. Instead I
listened to the unit myself in several places and then in my own system, as
well as listening to several other players with DVD-A capability. That is
the unit I recommended, based on my own listening.
No amount of tap-dancing about on your part above can change these facts
Arny. Your memory was faulty, and I simply pointed it out. No big deal,
except perhaps to somebody with a poor ego.
Your mastery of the obvious is amazing, Harry.
And once again Arny you practiced your old trick of simply snipping (without
indication) the part of my post following this sentence, which clearly
reflected back on you.
You not only can't stand the heat, you run out of the kitchen, pul down the
blinds, and won't even let anybody else know what's cookin'.
Harry, the portion of your post that I snipped was
irrelevant to my comment. Sue me for trying to keep the
discussion on topic.
> You not only can't stand the heat, you run out of the

Harry, discussing things with you would be more interesting
if you would take responsibility for your own errors. This
whole whine about my snippage is really the smoke screeen
you're trying to put up because you just erroroneously
claimed that SACD and DVD had the identically same dynamic
range, and also the mixed signals you've given to RAHE about
some of the Pioneer inexpensive universal players.
Now Harry if you are willing to admit that you were grossly
mistaken about the SACD versus DVD dynamic range issue, I
might be willing to continue forgive and forget your RAHE
comments.

**No. 4558 style chips have not been used in any decent equipment since
before 1980. Even pro audio equipment manufacturers stopped using them two
decades ago. They were resurrected by cheap Asian CD/DVD player
manufacturers awhile ago. Decent equipment eschews the use of them.

the 578 with the 563a. And no amount of huffing and blowing can change
that. All I have done is correct you.

I'm not looking for your forgiveness, Arny. I'm looking for some
truthfulness. Do you never look at the dynamic range measurements that John
A publishes on every high rez player. If you did, you would note that at
low and midrange frequencies SACD and DVD-A are IDENTICAL and that it is
only in the high frequencies that SACD yields to DVD-A in dynamic range.
That's what I said. It's fact. It's demonstrable. What's your beef?
Well, until the contacts get dirty.

Never saw the problem even though I've read people get

OK, so all this fairly new pro gear such as the power amp
for my NHT Pro A10s is indecent. Either that or it was made
before 1980 even though that model came out just a few
years ago.

I run into 4558s every once in a while in all sorts of gear.
Just because Trevor is paranoid about them doesn't mean that
everybody is.
Yes, 4558s aren't the greatest op amp in the world, but they
are still being used to make quality new equipment.

Harry, as is your usual lying habit, you're changing the
topic from where you made your gross mistake to something
that sounds like it to the naive readers. In this case
you're changing the topic from the dynamic range of the SACD
and DVD-A formats which is where you made your gross
mistake, to the performance of real-world SACD and DVD-A
equipment.
Harry, when you are willing to start treating me with the
tinyist amount of honesty, I'll consider responding to your
posts again. But I know that you are unable to stop lying,
first and foremost to yourself.

**If it uses a 4558-style chip (and depending on how it is used), then it is
crap. 4558-style chips have been available since the late 1970s. There are
far better performing chips available. Such chips are inexpensive and have
been available for decades. Be aware, that I have no issue with 4558-style
chips as part of DC servo, or in LF circuits.

The industry standard opamp is still the NE5532/5534/LM833.
4558s are highly sought after by guitar amp enthusiasts.

Couldn't agree more, Dad bought one in early-83 and it's stored away (with
tuner). The picture quality from the tapes from that period is superb (much
better than some 8mm analogue footage from the 90s). Unfortunately it has a
few mechanical problems - nothing that couldn't be fixed I suppose.

Close enough to zero to essentially shunt all of an amp's

This, from a guy who claims that his special amp (or one

qualities that set it apart from all other decently designed
versions. Yeah, it may sound different, but if so that is
because there is something seriously wrong with it.

Not only that...they are easy to fix. I've had two repairmen swoon over the

Harry, I really do not know what you are trying to sell.
The only advantage SACD and DVD-A have over the CD is
surround sound. Ironically, Dolby Digital and DTS can do the
"subjective" job in that area as well as the so-called
high-resolution formats. In addition, a good, home-based DSP
synthesizing device can take a two-channel CD and often make
it sound subjectively BETTER than the remastered SACD or
DVD-A version, which, if we are talking about older original
releases, are often taken from two-channel masters and given
the DSP treatment by the recording engineers prior to
producing the new version. Note that this refers to
concert-hall realism with classical material and not pop
recordings that often have instruments all around the
listener with SACD and DVD-A versions. Obviously, no amount
of home-based DSP work with the two-channel versions can
duplicate that. But who here with any musical taste cares?
In any case, the dynamic range and extended bandwidth
"advantages" of SACD and DVD-A are meaningless
embellishments to an existing digital technology that needs
no such thing to make music sound more dynamic or
transparent.
Phoniness has finally taken over audio.

That's the point, it only neuters
one set of preconceotions
And if the person has preconceptions
that they will sound the same, the test WILL NOT
neuter those preconceptions.
DBT tests for audio are actually designed to
provide a biased result of there being no difference.

See, you are using a test for the purpose of
arriving at a predetermined result.
It is NOT a proper test. The DBT test is no way to tell
if those that have a predetermined bias against hearing differences
are actually NOT hearing differences, or if
they are merely 'deluding' themselves in ignoring
differences that actually exist!

As one real expert posted previously, yes, it is not zero
ohms. But for all practical purposes, when it is in parallel
with a speaker load it might as well be zero.

Good. That means they sound like all other good amps, at
least up to their respective clipping levels. If you say
otherwise, you are a con artist.

I know enough about them to realize that when somebody like
you claims that a super-duper amp he is dealing with sounds
superior to all others that individual is pulling a sales
scam.

Maybe so. However, additional education in the realms of

I can fairly listen to the things, pal. I can compare at
matched levels and can determine that exotic technologies
notwithstanding, all good amps sound the same up to their
respective clipping levels. OK, with really wild and weird
speaker loads some amps have advantages. But with the
speakers most people use, amps is amps. And there are
conventional amps out there that are also able to handle
rather weird loads. They may cost a bit more, but there is
still nothing exotic about their design.
> You
> have no experience with the amp in question anyway.
I have heard and compared enough good amps to know that if
your amp sounds different from them there is something wrong
with it.

I can spot a con artist, and it this day and age that is
more important than the ability to spout technical jargon

OK, here is your chance to repent. Admit that all good amps
sound the same up to their respective clipping points when
driving normal speaker loads and admit that for home-audio
applications good, decently thick lamp cord works as well as
exotic speaker wire. If you say that I will apologize for
what I have written about you.

With $2000 USD you can browse "e-Bay" or "Audiogon" websites for these:
Meridian 508-24, Pioneer PD-95; Accuphase DP-65V or 70V...etc I have heard
them in action and they are awesome machines and you can probably pick one
up for much less than $2000 USD from the mentioned sites.

Close enough, actually. It has plenty to do with you,
however.
That you con people into getting into an excitable twist
over the so-called superior sound of any kind of player (CD
or DVD, or whatever), particularly if we are talking about
per-channel sound quality (rather than surround-sound
abilities) shows that phoniness has indeed taken over audio.
Sure, some players hold up better than others, but even then
price does not necessarily determine which player will last
and which will not. However, in terms of actual sound
quality I will opine that a good Best-Buy or Circuit City
offered DVD player costing $100 bucks will sound as
subjectively good playing CD recordings as the very best
exotic player you come up with. Yes, your player might have
a measurable edge, but the ears will not pick up on that
advantage.
Yeah, I realize that selling people on high-end and
high-priced sound is important to you. It isn't important to
me, however.

Any good player selling for under $200 (note that he did not
say $2000) should work as well as any exotic selling for any
price. When it breaks, replace it with a newer model selling
for about the same thing. You can buy a lot of cheap players
for what one exotic costs and as long as it works OK it will
sound as good as any of them.

You are just trying to rationalize the fact that you simply
must have something exotic and esoteric to believe in. (That
this involves audio gear and not some kind of religious
deity and a need for salvation shows a monumental smallness
of mind.) That you place expectation effects higher up on
the scale than simply not hearing differences during a DBT
says more about you as a true believer than it does about
any kind of audio gear.

But most listeners would never hear those differences when
listening to musical source material, particularly for
pleasure.

This is baloney. You either hear differences or you do not.
Howard Ferstler
Take a good look at the test methodology, it only accounts
for eliminating one side of the expectation effects, the expectation
that there will be differences. It does not address eliminating expectation
effects, based upon an expectation that they will sound the same. Thus,
this so-called "unbiased" test is actually quite biased towards
producing your "expected" results.

But you do need to properly level match, and you also need
to go the DBT route if the participant has preconceptions
about a favored amp or set of wires sounding superior. If
you do not employ the DBT protocol there is no way to tell
if the participant is hearing differences or simply
imagining things - or saying that he hears differences in
order to sell a product.
Well, we have all gone over this many times before.

First, I served four years in the USAF as an electronics
technician, and so I do know something about electronics.
Not college level, but not chopped-liver level, either.
Second, I know that if you put a speaker in parallel with a
load that is but a small fraction of an ohm no significant
sound will come from that speaker. How could it when the
vast bulk of the current flow is heading through that
borderline short?

Yeah, but below a certain point ultra-super measurements are
gilding the lily. I claim that even a good, mid-priced
receiver will have as good an amplifier sound as your exotic
amp. Add to that the existence of a preamp section, surround
sound (still more channels) and a tuner, and the receiver
wins the contest, hands down. Your amp is a money pit.

Well, they will do me no harm, whatsoever. On the other

They sounded the same as all the others, tweako. What else
do you want other than they all sounded the same? Actually,
the Son of Ampzilla unit I recently reviewed was
bulletproof. However, with normal speaker loads it sounded
no better than a rather old Yamaha integrated amp I had on
hand. Admittedly, the speaker load was not particularly
demanding.

Well, you are the guy who claims that the amp sounds
"better" than most of the competition. If the competition
all sounds pretty much the same, I think that we can
conclude that those amps sound that way because they have
inaudible distortion. I mean what is the chance that all of
those somewhat different topologies all had identical
audible distortions? If your amp sounds different from the
crowd, as far as I am concerned it is less accurate than
they.

Hey, I never said it would not shut down. I simply said that
at any level it would not be able to put any sound into the
speakers. This would be the case, because the VAST bulk of
the current flow would be through the shorted-together lead
in parallel with the speaker.

Just follow the guide I wrote below.

And now I suppose you are going to say that your very
special amp has specs that are superior to all (or at least
most) others. My contention, however, is that once you get
below a certain audibility threshold all amps, including
yours, assuming it is properly designed, sound the same - at
least with standard speaker loads and below clipping levels.
The funny thing about you is that you probably sell people
speakers that require an amp like yours. You basically force
people into a situation where they have to purchase an
exotic amp to power those oddball speaker loads. Yeah, I am
sure you do not do this all the time, but when the
opportunity knocks you step up to the plate and take a swing
at the ball.
> decently thick lamp cord works as well as

> **For most systems, yes. For SOME systems, no.
Systems that nobody would use in a typical home-listening
environment. Tell me, just how often do you recommend heavy
lamp cord for typical home installations? Do you push the
exotic stuff even in those more mundane situations, as well
as in these situations that involve SOME systems?

Bullshit. What you mean is that ABX doesn't support your absolute

'Chinky cheapies'.

Bullshit. They're used every day by mainstream manufacturers to
determine whether design changes had any *real* audible effect.
Like most of the 'subjectivists', you're ignoring reality to push your
own prejudices, and bitching about ABX because it doesn't support your
fantasising about the sound of 'high-end' equipment.
Bullshit. Those tests are taken by people from both sides of the
fence. The results are the same, only the reactions vary! :-)
