So first let me get this straight...all the denon's this year have the same sound quality, just different features and watts??? Now my question is, will an AVR-2312 or AVR-3312 sound better than the AVR 3808? I have a buddy that has a 3808 and is considering upgrading but first wants to make sure that if he did indeed upgrade to either the 2312 or 3312 that he would notice an improvement in sound quality. He doesn't care about video processing. Basically what I am trying to figure out for him is whether or not the dacs, dsp boards ect...are of better quality with the 12 line than with his 3808?
