Amp for B&W 802N

Classe amps and B&W N802 speakers are great match. So much so that B&W owner bought Classe. For your price range, I would look into a Classe CA-301. If you can afford more, CA-401, CAM-350, or CAM-400 are great. I have CAM-350 with my B&W N802.

Krell and B&W are a great match...I had the 801 Matrix III's with an old Krell KSA-250 and the Krell controlled the woofer the best of any solid state I tried which included a 350 watt/channel Rowland mono amp.

MCintosh MC 501

Cary CAD-500 MB. I realize that these are above your budget ($4,000 - $4,500 used), but they are absolutely the best match I heard with the Nautilus series. My second choice for the 802N's would be McIntoish MC501s. I would strongly prefer the Carys though. It's amazing how tube-like rich and liquid they sound. Dennis Had did a terrific job tuning them to sound like his best tube offerings combining it with all the effortless dynamics and bottom end that only monster solid state amps can deliver. These amps can put out 1,000 watts into 4 ohm with lots of healthy current. That's exactly what the B&W's need to sound their best. You should definitely try them out. Their rich and lush midrange will provide a very synergistic match with the B$W's slightly dry upper mids and treble.

thanks guys, I love A'GONE. Looks like Classe 301 or 401 would be lowest in price. I'll be looking for them.
What's interesting none of you suggested ML332. Any reasons why I shouldn't consider them.
