FWIW the m-audio audiophile firewire has worked flawlessly from my iMac. Sound is not as good as from my CD player, but is fine for background music use. One day I'll upgrade it, but, it works fine. I've also been using it to slowly import my LPs into iTunes.
DACs: Airport Express vs waveterminal vs mini-dac
I know this is impossible to quantify, but with a good stereo system (Cayin TA30 tube integrated amp & Green Mountain Audio Europa speakers), what's the magnitude of difference using the following dacs?
Airport Express (I already have the AX, and can connect it to the integrated amp with RCA's [analog])
Waveterminal U24: computer to USB to waveterminal to amp (waveterminal does the DA conversion)
Inexpensive DAC like ART DIO with waveterminal: computer to USB to waveterminal to ART DIO to amp (ART DIO does DA conversion)
Apogee mini-dac: computer to USB to mini-dac to amp
Other?
What's the best bang for the buck?
