USB/Fw DAC with volume control


I'm looking for the source (DAC) with the computer interface (USB/FW) and variable output for connect to power amp without preamplifier.

Variants:

MSB Analog DAC 384kHz
Weiss DAC202
dCS Debussy

What is better?

Not aware of anyone that has done a direct comparison between these DACs (and I have been reading up quite a bit on DACs). If I had to roll the dice and buy blind I would get the MSB. Another contender is the Bel Canto 3.5vb with the external powersupply. Stereophile compared the Weiss, dCS and Bel Canto, and preferred the Bel Canto (also the cheapest).

I have auditioned (in my system) both dCS and MSB. Out of the two, I would choose ... Berkeley Alpha DAC and Alpha USB. To my ears, it represents the biggest bang for the buck. AnalogDAC would be my second choice.
