Just bought one (AV-710).
I have had a Via Envy card in my HTPC for a long time now. I recently got fed up with the on board nVidia audio I had. Had some cash around and finally ordered an AV-710.
WHAT A DIFFERENCE.
Line in on the nVidia - buuuzzzzzzzz, sound, buz, sound, buzzz, move mouse - loud buzzzzzzzz, sound, etc...
Line in on the AV710 - sound sweet sound, no buzz at all.
Will not even mention the audio output capabilities. My old school 2.1 Boston Acoustics have never sounded better and cleaner. One of the best $25 investments I have made. I am sure that I will have this sound card for years.
I wonder though, does this card have the Wolfson rear (and switchable) codec that the Maddog does? It would be nice to use this card with a 2.1 system to its full advanatge. I could also just swap this card with the one in my HTPC that has the Wolfson.
