I was going to give this a dramatic title ("One Man's Journey" maybe) to attract your attention, but really it's been a smooth process. I thought I'd share my experience here, as I know some readers are still at the stage of deciding whether to take the B2 plunge. I was in two minds before buying: I loved the concept of the B2 and the company's commitment to support and continuous improvement, but I also saw some mixed reviews and a lot of issues being raised here. I'm really glad I went ahead.
I started the ripping process using the B2's internal CD drive. It worked well, but a small number of CDs froze so I added a cheap external drive (one of those mentioned on the Brennan website) which was certainly faster and quieter. But I was still getting some discs freezing and some not recognised. Coincidentally, I had a 21 day free trial of dBpoweramp (dBp) software, intending to use it to convert some high-resolution files to a level of FLAC the B2 could play. I'd imported them to the B2 from a memory stick but playback was stuttering. Once converted to CD quality they were fine. So I tried that software for ripping CDs on my laptop and since then have rarely ripped direct to the B2. I should stress I don't think there's anything wrong with the B2's approach to ripping, it's more likely I have problems with a few of my CDs. While dBp has ripped everything I've given it, it has flagged errors in some tracks which I've then been able to delete individually before loading the rest of the album to the B2. I suspect that when the B2 rips were freezing it was also finding a few tracks with problems but had no way of telling me. Also, dBp checks more widely than the B2 for track listings and album art. It still fails to find albums sometimes, but allows me to check that I'm happy with the artwork, album and artist titles and track lists and/or to type things in before ripping. I find it particularly useful for compilation albums and classical CDs where I can edit exactly what information I want. It just works better for me: all of that would be possible on the Brennan UI, apart from dealing with the ripping errors. There's a bit more work transferring files to the B2, but dBp will rip CDs direct to FLAC format, so there's no need to compress on the B2 later.
Other issues: I tested my wifi strength and found it was only just good enough to use the B2 as Network Attached Storage. It was fine for everything else. I got a new wifi dongle with an antenna, which improved the strength a lot. I also found I could improve the strength enough, but less dramatically, just by putting the supplied dongle on the end of a short (30cm) USB extension cable.
I haven't connected speakers to my B2. I use an optical cable into my hifi. I found the stereo channels were reversed, but there's an option ("L-R swap") in the B2 memory which fixed that and it's been fine since. I tested some really good headphones recently for someone I know and used the B2 as a source for part of the test (though through the hifi amp): I was very impressed by the quality of the CD rips and the absence of background noise.
I have two external hard disk drives to backup what's on the B2, just in case. I bought both from the Brennan shop. Recently I've been using the instructions posted here by Peter Lowham, whose hard work has overcome some previous problems with larger backup volumes. I understand a solution is in sight which may be implemented by a web upgrade.
All in all, it's taken me longer than I expected - three months - to rip and catalogue my CDs in the way I want them. But, as others have said, you only do it once. I can now search for tracks and create playlists without getting out of the chair. I know this is not necessarily a good thing, but I promise to walk the dog more. Most importantly, I've rediscovered my CD collection, which had been pretty much just gathering dust for years. Also, I'd like to add a bit of praise for the B2's quality as an internet radio player. I have the function on my hifi but have never used it - too complicated - but on the B2 it's easy and very good. And finally, whoever thought of adding the YouTube search and cache facility to the B2 deserves a big medal of some sort. There's a lot of great music on Youtube and being able to access it so easily and at such high quality is a B2 bonus which is rarely mentioned.
