I recently buyt a USB Extigy Soundblaster. It has a hardware Dolby Digital Decoder. I will connect this one directly to my Amp. Volume will be controlled by a Griffin PowerMate Knob (ordered, but still waiting for it). Depending on the quality i will remove my stereo then. I will let you know, but it will surely take a week or more. Btw. does anyone know a Amp with digital Line In ?
