So, my birthday is fast approaching (February 1st) and I'll have to decide soon. I think that it is going to be one of these two options:
1) Cambridge Audio DacMagic http://www.cambridgeaudio.com/summary.php?PID=320
2) Scott Nixon USB.UFO.JF http://www.scott-nixon.com/dac.htm
The former is a touch more expensive, but I can use it for more than one purpose. The latter may sound better, but without hearing them side by side, it's hard to say. They represent two very different approaches: Oversampling vs. NOS and multiple interfaces vs. USB only.
So, what to buy then....
