Sonos DAC

The Digital Lens is a good solution, but it was made for CD's, not streaming audio, and as a result it expects the music to stop after 10-15 tracks. If you have a long playlist, it will overrun or underrun the FIFO and start popping. A better solution is the Pace-Car which has a similar function to the Digital Lens, but can provide a clock to the Sonos. This will never underrun or overrun no matter how long the playlist.

So I just learned the hard way about how poor the support is for WAV files within Sonos. I ripped my entire collection (300+) CDs and setup my Sonos system only to find that the only way to play tunes is navigating a file folder structure. Ugh!! I really wish I would have read the Sonos primer on their site first.

So now my question is...convert to FLAC or Apple Lossless. Given that I also have a few iPods, wouldn't Apple Lossless be the one to use? From what I've read, there is absolutely no advantage to FLAC from a metadata(tagging), file size or audio quality perspective. Is that right? Seems like most people use FLAC just because they don't want to support Steve Jobs and his quest for world domination. :-)

you should really listen for yourself to see if you can tell the difference between FLAC, apple lossless, mp3, ogg, etc. Personally, I noticed a slight difference between mp3 and FLAC which manifested itself in a lack of soundstage and a loss of microdynamics. However, given my large music collection (5000 cds), I thought it was worth it to rip to a smaller size file (256 VBR).
