I just received this dac price is right $500. Yes I know not a very expensive dac. The reason as I'm being conservative so I can get a taste for pc audio. I can tell you this dac sounds fantastic. Apparently it compares to a benchmark dac if not better.
My setup: Mini Mac 2gigs ram> nuforce dac hdp> toslink nuforce cable> drobo harddrive machine> aesthitix pre amp> nuforce amps v3 >acoustic zen absolute speaker cables > nuforce single ended cables connected to my preamp. check it out you won't be dissappointed. Hell its only $500. Also check out pure music software there is a 15 day trail version.
