I've managed to win one off ebay for£650 including p&p. I was all set to buy the 3802 for obvious reasons. I'm well aware that it has more upto date features than the A1D, but the point is, i only require an amp to do 5.1 duties, NOT 6.1,7.1 etc. Sound quality in 5.1 and music stereo mode is my greatest concern. So my question is: Is the A1D considerably better in SOUND QUALITY in these 2 modes? I would certainly have thought so. Even though it's 3 years old, it got amazing praise for it's power and musical ability. 140w per channel and analogue music processing. Or maybe technology has trickled down into lower priced amps making it less impressive today??
