So we're all pretty jazzed about the Wave Audio DAC, it's a long overdue product. In principle, I am too, but in practice I've already invested more than I should to put a (way too) high end DAC in my main system, and I just can't rationalize the cost for a bedroom system that sounds good, but is worth at most $1000 at this point. So far the best solution I have is USB from the laptop into some sort of USB to PCM converter (e.g. M-Audio Sonica Theater or similar), then digital coax into a DAC--which is getting pretty roundabout and kind of pricey for what I'm trying to do. Anyone have any recommendations or information on d/a conversion options that begin with standard computer ports (e.g. USB, firewire)?
