"About two weeks ago I ordered the Chaintech 7.1 Soundcard for the ridiculous low price of about $19 at BananaPC (it is out of stock now) to upgrade the stock soundcard in my 2002 Media Center PC. Ever since I've connected my HDTV TiVo to my Onkyo HT-R510 I've been enourmously impressed by the improvement in the sound quality going through a fiber optic cable vs. the old analog connection. So I figured buying a new soundcard for my MCE machine for a mere $19 that supported fiber optic out was a no brainer. All I can say is wow -- my mp3s have never sounded this good. The improvement in sound quality going through this card and the fiber optic connection to my Onkyo is amazing."
I have had optical outputs on my sound card for a long time and my iRiver supports it too, but I never bothered using it on a regular basis, only briefly for a test. Do any of you use optical I/O for audio on a daily basis? Have you found the sound to be better than that over copper?
