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).

Thank you in advance for your time.

Well I have the advantage of hearing all of the products above, and can tell you, it really takes a lot of guts to recomend a niche European brand versus the big guns. The reason behind this is simple , the Phonosophie sounds better, especially in an active system, because the brand itself has a mindset towards active setups. As far as chassis goes, the Phonosopie is better in real life than in pictures and I could hear no sonics artifacts caused by RFI and EMI.

I was told by a B&W representative at Munich high end show, that the Linn Akurate 4200 will not be powerfull enough.
Anther candidates are 4 x Plinius P10.

Goodness Sphere, you must get around. Where did you have the pleasure of hearing the Rowland MC606 as a tri-amp solution or as part of a quad-amp? What were its shortcomings vs the Phonosophie equivalent?

Rowland has (or had two weeks ago) the 606 set up in a tri-amp configuration driving a couple of custom Magicos (not anything you've seen in the audiophile mags).

My apologies, not the 606 but the 501s and all the reference Krells and the ARCs. I recommend the Phonosopie only because the situation demands an active setup. Let me put it this way, the Krells, ARC and the Jeffs make Kari Bremnes sound like top High end gear playing within varying degrees of audiophilia, the Phonosopie made her sound closer to human with a lesser degree of audiophile pyrotechnics. Anyways its just a recommendation, had the requirement been for a passive loudspeaker I would have gone another route depending on the speaker.
