OK, I know this is a hifi forum, but I believe this product deserves a mention. My mate has just bought one to hook up with his Pioneer A400 amp and Wharfedale Diamond 8.2 speakers. The sound quality of this sound card is very surprising. Very musical, with excellent bass, and crystal clear, detailed, smooth treble. Playback of MP3's using Foobar 2000 and 24-bit Fixed Point decoder is certainly an ear opener, surprisingly good indeed. This sound card can easily rival, if not beat any budget CD player that I have heard, certainly sounds at least as good as my Cambridge DAC3. Highly recommended.
