Amp for Nautilus 805 - Krell KAV or Classe cap 101

for what it's worth I'm auditiopning a Krell TAS 200x5 with N802's for 2 channel, and N804's and HTM1 added for HT. I've found none of the harsh brightness others reference (using little ol' cobaltcable ultimate speaker cable...solid copper)and when I spoke to Krell and B&W they each foavorably referenced the other as showcase partners for the Nautilus and KAV lines...

Thanks for all your comments.
I guess Krell KAV might not be a good option.
I will have to go with a CAP, but I am not sure I can afford a 151.
Thanks again!

If you're happy with the Musical Fidelity sound, consider bi-amping as a cost-effective option that will maintain the system's sound. I had a pair of A3cr power amps controlled by the A3cr pre driving B&W 602. Though the 602 is clearly not in the same league as the 805, which I considered, the extra dynamic headroom from two amps made a wonderful difference. The the system had shattering dynamics. My experience suggests that B&W can eat a lot of clean power. I also found the MF - B&W pairing worked very well.

Though I have moved to other speakers, I now have the Krell KAV 300iL powering the stereo. The 602 are still sitting around, and I hooked them up to the Krell for kicks. I did not find the partnering objectionable, but I don't find Krell to sound bright, either.

It could be the case that you cannot drop a Krell amp into the system and judge immediately. The Krell's famous iron grip, high current, push-pull, fully balanced design further breaks in the moving elements of a speaker. After this second speaker break in completes, the pairing may sound better.

I have no experience with Classe products.

B&W does not design on Classe amps. They design them on Chord stuff.

I believe before that, it was Krell.

McIntosh also is typically used with B&Ws.

I am quite new at this but my setup consist of Nautilus N805 and a Classe CAP101 newest model.
The CAP 101 has plenty of power for the Nautilus. If I had to do it again I would maybie consider the CAP 151 but I could not tell you why (I guess because it's the biggest of the integrated). Some thread above mentions that B&W and Classe and tunned together. My dealer told me exactly the same. I am to new to state the difference between the 101 and 151, I mean sonically. Everyone can read that the design is not the same. The 151 probably has more reserve and a tad more bass. It is also 500 more $$. My next step will probably be CP47.5 and a CA101 leading to CA201 down the road. Classe is not for the analytical, pencil and pad technical freak analyser person who only wants to hear how an amp can reproduce sound. It is on the smooth side and is never irratating. Many poeple pair the Cap151 with N805.
