Wouldn't another solution to be replace your computer's current sound card with one that has better quality audio, even if it is analog? I am using an M-Audio Delta 44 which is actually a production level soundcard, with 1/4" outputs, and the sound quality really is perfect. It cost over $500, but M-Audio has a pretty wide range of soundcards, even in the consumer level. I can't reach their site right now, but try looking into them if replacing your soundcard sounds like a doable solution. www.m-audio.com
