what is the best amp for B&W 802N

I biamp with the A3CR on top and the A300CR on the bottome. This gives me plenty of power, and its easy since they have the same gain. You can pick up a used A300 for what you want to spend.

A pair of Classe CAM 350 (mono blocks) should do the job.

Over the last couple of years I've upgraded my electroncis (CD player and amp) and cables and found that my B&W 804N remarkably improved in sound with the upgrades. This indicated to me the B&W 804 are quite a refined and transparent speaker and require quality electronics and cabling to sound its best. I would think the B&W802 would be the same.

The new Delta amps from Classe are a perfect match for the B&W's. I would assume that the older ones are good too. The N802's can use as much power as you can give them, but don't skimp on the quality to get it. Best match I've heard is the CA-M400's.

My friend uses a pair of ML 333 to drive his N801 (bi-amp), and it is the best sounding system I have ever heard approaching life music able to play real loud without strain like with single 333 amp. With this said, you can throw as much "good" power as you can to your 802N, the sound will just get better. I would recommend you to save enough money to get ML, Krell or other high power tube amp to maximize the sound of 802N.
