I just upgraded my dedicated mp3 jukebox (connected to a Sony 100w stereo receiver) soundcard from a SBLive to the Chaintech AV-710. I am using the high quality channels 7+8. This soundcards make even low bit-rate mp3s sound good. It is a little quieter than the SBLive; meaning I have to turn the volume up a tad on the receiver, and the bass needed a little boosting in Foobar2k; I can't do kernel streaming since the CPU in the jukebox is only a 500mhz Celery. But, overall I am impressed with this $25 soundcard.
