I own the PS Audio DAC with bridge and feel it was one of my better investments. To not get the Bridge interface, in my opinion, is to cheat yourself. And really, why even get this DAC if not for the bridge? I've come to the conclusion that most issues people post about on here and PS Audio's forum are network related. Build a strong infrastructure and be rewarded. This DAC is not cheap, and most likely your amp/pre/speakers aren't either... Invest in gigabit, CAT 6, dedicated server/NAS.
That being said. I use my IMAC connected via wireless N 5GHZ to an Airport Express downstairs, which is then fed to the DAC using CAT5e... I can stream 24bit 192 AIFF files without any issues for hours on end. I would say two times a week, I may get a song that pauses during playback or Elyric freezes. No biggie, I hit play and it continues.
These drawbacks are nothing compared to having to get up, eject a disc, walk to my cabinet, find the case, decide on the single CD I want, walk back to the cd play, etc, etc.
Being able to create playlists spanning 10 different albums, some 24bit, some 16. It just doesn't get any better imho.
