Reccomendations for Nautilus Speaks

Just put 802's in front and 804'2 for rears. Any reccomendation on amps to run these and the HTM1 center? I have a B&K 7250 with Ref30 right now. I want to start and plan upgrades to more efficient/cleaner power. Will do amp first and pre/pro second. Thought son what to drive these power hungry monsters with? Like to keep the amps and pre/pro setup under $15,000 if possible.
Bryston what to run 5.1 channel? I do a moderate amount of 2 channel listening as well.
2nd the Bryston. Try a 4BSST or 14BSST for the fronts and a 6BSST for the rears and center. You could find them used on AudioGon for way less than 15K. 20year warranty a plus.

When the Nautilus speakers were designed, B&W used Krell (FPB600 and 650m's) to voice them.
Try, if possible to use the FPB300's (used) for the main two speakers and good as you can afford for the balance.

Have fun,
Thoughts on this match up?
I meant Sunfire 400X5...Krell is probably out of reach for me, I'd prefer not to get used.

I have the exact same speaker setup that you do. You are right about the Nautilus speakers being power hungry. They sound OK at lower power but every time I have increased the power to them it has made a HUGE difference. Greater level of detail, larger soundstage, but most especially in overall dynamics. The more power, the closer they get to real live music in your listening room. Another good news/bad news trait is that they are very revealing of any strengths or weaknesses in the rest of your gear. Of course that's what keeps us on this endless upgrade path, right?

I am using bi-amping for all five speakers. The bass portion of each speaker is powered by the speaker outputs of a Denon AVR-5803 receiver (170W/channel @ 8 ohms), and the mid/tweeter portion of each speaker is powered by a B&K 200.7 amp (200W/channel @ 8 ohms). The pre-outs of the Denon receiver for all five speakers are run to the inputs of the B&K amp. It may seem like the bass portion of the speakers should get the larger amount of the power, but I tried it that way and it sounds much better with the mid/tweets getting the lion's share. Also, I use a Velodyne sub for everything below 60 hZ, so that the bass portion of the speakers don't have to work as hard as if they were being asked to go to the low, low frequencies. Bi-amping seems to give a much cleaner sound than bi-wiring. I have tried it both ways.

I talked to B&W about this setup and they encouraged it. I was concerned about overpowering any portion of the speakers, especially the 804's or the HTM-1, which are rated at a much lower power than the 802's, but they said it would not even come close to overpowering the speakers. One of their engineers said that the biggest danger to speakers such as these is to underpower them. If you are not going to use a receiver, and only a pre-pro with an amp, you could possibly use a pre-pro with two sets of pre-outs. I don't know if there is such a setup available. If there is, then you need to make sure that both sets of pre-outs on the pre-pro are output at the same time.

I am extremely happy with the B&K amp, it is extremely clean, detailed, and dynamic. And made in the USA.

Also, I run everything through a Monster HTS5000 Power Conditioner/Filter that turns on when the receiver is turned on and then turns on the B&K amp and the sub with a slight time delay. The thing that made as much difference as any gear upgrade or boost in power is adding a dedicated 20-amp breaker using 10 AWG Romex, strictly for all of the home theater gear. Going up to that much power with the amps, etc. requires a larger source of clean juice.

BTW, I also do a lot of two channel listening, and once you get the 802's and your new amps, IC's, etc. broken in, you will be amazed. I use CD, SACD, DAD's, LP's, and occasionally DVD-Audio as two channel sources, and the sound quality through the 802's is truly awesome. Not just my humble opinion, but confirmed by many other listeners, including musicians. Even the wife now sits down and enjoys the music.

Good luck with your search and have fun with it.
Under 15k?

For amplification Pass Labs x250 or x350 would be my #1 choice for the Front L/R. And maybe a Pass Labs X3 for 5.1 or x5 if you might go to 7.1.

Pre/Pro....Hmmm I love my Bryston SP1.7, I think its hard to beat but, I would check out Krells HTS, Classe's SSP-75, maybe a used Lexicon MC-12, and even a Sunfire TG3.

You could tweak it for far less, A used X250amp($3000) for the front, use your existing B & K 7250($0) for the rest, and tie in a nice 2 channel preamp($2000), keep the ref30 for DVD and multicchannel purposes and viola. Only $5k spent, and I bet it'll sound impressive.

Just my 2 cents
Try Classé products. The Nautilus tweeter a bit hot and hurting your ears if you matching with Bryston or Krell. It is also depends on speakers cables and interconnect too. I think that the reason why Classé now under B&W wings of marketing.
I disagree with the above post by Amthanh,The Classe Amps are very good,But they do not have the tight bottom end control such as the Krell and Bryston.The tweeter on the B&W Nautilus is a metal dome type,I believe that the Source and the pre-amp are the governing factor if the B&W's are to sound their best.The older Krells are on the hard side,But the Cast And CX series of amplifiers are among the best I've heard,I'am currently using The FPB 700CX to drive my Nautilus 802's,also The Bryston 14B-SST and 7B-SST are also very refined and smooth on top.
Plinius Amps make a great match with B & W Nautilus speakers.

I've heard the SA-250 Mark IV with the 802's -- sounded great.
I searched for an amp to mate with my N802's for two years before deciding on Simaudio's W-5. I use the W-5 with Simaudio's P-5 preamp for music. It's a very nice combination. (This would only make sense to me if you are really into music rather than home theater.)

I guess I disagree with suggestions that would cause you to spend a lot of money on amplification for your HTM1 or N804's. I use the HTM1 and SCM1 and find it very difficult to believe that high quality amplification would make a difference to my enjoyment of a movie.
