I would also recommend the Krell KAV 1500, which is a 300watts/channel x 5 channel amplifier. Krell recently updated the cosmetics on their multi-channel amps, chaning to a sleeker-looking metallic sliver for their new home theater line-up. They have also combined their multi-channel amps, from the the KAV-500, which is a 100watts x 5 channel amp, and the KAV-1500, which is a 300watts x 5 channel amp, to their new amp called Home Theater Amplifier Standard, which is 200watts x 5 channels, with a new look and a higher price.
The specs on the KAV-1500 and this new model are exactly the same, except the KAV-1500 has a lot more power (you can check out info on the Krell website). Because the KAV-1500 is being discontinued, you can get a brand new one for $5,000, which is a terrific price given that its list price is $8,500.
I bought mine on eBay through a Krell dealer in North Hampton Massachusetts called Spearitsound. They have a Krell KAV-1500 on sale almost every other week while supply lasts. You can also check out their website at www.spearitsound.com and can buy directly from them. My unit came completely brand new in factory sealed box, and their service was terrific. I also paid for the unit with a credit card.
As to the sound of this unit, it is the best sounding class AB amp I have heard. You would probably have to get a Krell class A amp to have a better sound. I have listened to many AB amps, from two to three to five to six channel amps, and from many brands. In my opinionl, I liked krell the best. I find it to have incredible dynamics, terrific high- and low-end extension, and litterally everything else for home theater.
I am a home-theater enthusiast and I also listened to quite a bit of audiophile-quality CDs. I am quite happy with my system with the Krell KAV-1500. For your reference, I have B&W Nautilus 801 speakers and this amp has no problem in giving them all the power they need!
Good luck in your selection!
