Hi, I bought this denon amp in Russia abt 18 months ago ( someone mistakingly told me av equip. was hell of a cheap there). It seems a good amp but I've never it seen it reviewed in this country, just the 2802. Anyone know where I can see a review of the 2801 or anybody have this amp and have any comments on it ?. I run it with M74 floors , M77ds rear, M7c1 centre and M70 sub. I think the sub may not be compatable and am thinking of upgrading and am also going o change the centre for an M7c2. Otherwise I think everything sounds ok. Also what benefits could I obtain if I did consider upgrading this amp ?
