I have have just purchased a Denon AVC 1SE amp to replace a Denon 3801. I have found that the sound quality of the Denon AVC 1SE is nowhere near as good as the 3801 especially Neo 6 in music nor cinema mode. My 3801 sounded very dynamic with music through CD or MTV on Sky but the 1SE sounds poor in comparison. My speakers are Mission 773 fronts, Mission 77C1 centre and two pairs of Mission 77DS rears, which I know are not up to the quality of the amp but surely my 1SE should knock spots off the 3801. Do I have a faulty amp? Please help.
