I currently have a Denon 1802 driving a pair of Boston Acoustics VR-M60 fronts, a VR-MC Center, Energy Take2 surrounds and a SVS 20-39PC. The setup sounds good, but the receiver seems to lack oomph (power). I am about 70% music, 30% HT. I would like to improve the sound quality, volume and features. The 3802 and 4802 look interesting at 110W and 125W or so respectively - I am guessing either of these would improve sound quality at low volume, and enable louder volumes. The 3802 seems reasonably priced at $900, but I wonder if the difference between it and the 1802 is sufficient to warrant the cost of the upgrade. The 4802 is about $1800, why is it double the cost of the 3802? Or, I guess I could by a 5 channel amp for my 1802 now, and upgrade to a better receiver *or* Pre later. I am open to other manufacturers, but for no particularly good reason I am partial to Yamaha and Denon. Does anyone have any suggestions?
