I use the UA-5 and it sounds pretty good for its price and never causes crashes...
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?
