I think that I'd go with a Weiss DAC2 before the Bryston, especially if you are interested in computer audio. FWIW, I tried a Berkley in my system, and didn't feel it was a significant step up from my Benchmark- a better soundscape, but with less PRaT. FYI, the unit I bought used was slightly damaged in shipping due to the original packing being rather limited. It appeared as if the foam supporting the sides was inadequate, and the BNC socket became slightly bent. In dealing with this I got a taste of Berkley's customer service via the original owner forwarding emails to keep me informed. Not only were they going to charge him $200-300 to replace the socket (completely accessible $5 part on a 6 month old product), but they wanted a similar amount to upgrade it to the current product. Forgive me if I am off base, but as a manufacturer myself (non audio) I feel as if they should have updated it for free to current specs and be grateful for the opportunity. A DAC isn't an amp or something that has a lot of pricey components. A lot of what you are paying for is the design. If after less than a year they are already making changes, then their design was fully executed in the first place.
I'll wrap up my rant, but keep in mind that if you were to buy a Berkley, don't expect much service for your $5000 DAC (as opposed to Bryston's warranties).
