At that level I would not cut corners with amps. If it was me, and I wish it was, I would have two pair of high end monoblocks with really good biwire coming out of each. Many choices available could go SS on lows and tubes on mid/highs or all the same. My gut tells me like all B&Ws they really excel with amps with lots of headroom. If not you can give them to me to figure out. Ha,Ha,Hee,Hee
Amp's suggestions for B&W Nautilus Prestige?
...I need advice on amps to drive these speakers (snail), budget is $20,000.
They are 4 ways with active crossover, I need 8 channels 100W- 300W.
Amps will stand on a rack- maximum height is 20".
I am using an Audio Research reference 3 and Wadia 581i se.
I prefer to have gain to every channel but it isn't a must.
I thought about 2 x Linn Akurate 4200 (4x111W each).
