I am running a Creative Sound Blaster Audigy sound card and since changing to Vista 64 bit Home Premium OS and downloading Creative drivers for the new OS the sound quality is CRAP as they have reduced the controlability of the unit. I am now thinking of changing the card for a Auzentech Auzentech Auzen X Meridian. I use the pc mainly for music can any one out there give me some advice as I am only a home user and not technical.
