I enjoy my desktop system and usually end up listening to it more than my main system. I don't know if one would consider it HIFI, but it sounds pretty good. I have my CPU streaming audio through an APPJ Miniwatt EL84 tube amp (oldschool RCA tubes), Topping D10 DAC, Fostex Pangea speakers with the Fostex FF105WK 4" Full Range Drivers and an REL T/5i subwoofer. Anyone have a good sounding desktop/Computer setup they want to share?
