I am confused, if the files are stored on the PS3 as WAV and it is sending them via toslink to the XDA-1, isn't it just a transport with the XDA-1 doing all the D/A conversion? Theoreticaly it should also act as a transport with a CD. If there is a noticable difference then the PS3 MUST be doing something to the signal. Anyone have any ideas I have a PS3 too and am curious as to what is going on.

In theory a CD and a FLAC/WAV should send identical bit streams down the PS3's digital interconnect. Same for a PC, if you've given the music app exclusive control.
But just as Windows' mixer will mix other applications' sounds into your audio stream (and possibly noise), I'm guessing the PS3 by default does this as well. Or is it smart enough to go bit-perfect when you aren't playing a game or something?
It should be easy to test. Hop around the menus while your music plays and see if it makes system sounds or not.

I don't know if that's a valid test...the issue with windows was that it mixed the audio and the system sounds by resampling everything at 48kHz. The PS3 allows you to choose valid bit-rates (frequencies) that your system can handle. So, if you check only 44.1, or even 44.1, 88.2, and 176.4, it could be that it mixes the system sounds with the audio, without the same harmful effects as the old Windows "kmangler". (Even if you allow 96 and 192, thus forcing it to re-sample the CD audio, it would probably sound much better than a 44.1 --> 48 kHz conversion).
