Pre and Amp suggestions for B&W Nautilus 804?


Does anybody have good info on the ideal preamp/amp combination for the B&W Nautilus speakers?
I had the 805s and now I have the 804s.
I have been using Classe Audio pieces.
I went from the CAP-80 to the CAP-151 to the CP-35 and the CA-101 combo.
I am looking for matching preamp/amp combos, solid state, with a warm character.
The ones that have gotten my attention are upgraded Classe, Pass Labs, Sim/Moon Audio, and Balanced Audio Technology.
Any imput?
Please have or have owned B&W Nautilus speakers.
Thanks,
John

I do no think I will do integrateds anymore.
The BAT integrated looks interesting; but for the same money, I don't know...
I am not interested in SSPs either.
Thanks for the imput, but I am looking for some feedback on solid state preamp/amp two channel systems.
I want them to be warm and have dynamic bass with amps rated at 120-200W into 8ohms.
Thanks for the cable imput.
I will look into those.
The ARCAM FMJ C30/P1 makes a great combination for the Nautilus, delivering great bass and outstanding warmth. Better than the Moon I-5 Intergrated.
I've had a pair of 804's for about 8 months. I've used them with SimAudio P-3 and P-5 preamps, and for amplification I've used an older SimAudio 4070 as well as a used Sugden Au51p. Both amps worked quite well. The Sugden is a 10 year old design, with lots of class A bias and good current delivery. I have had very good results using it on the 804's - it sounds tomally richer and more dynamic than the 4070. In terms of new solid-state gear, I'd probably recommend the SimAudio P-3/W-3 combo as providing a very high level of transparency, warmth, and dynamics for the price.

However, the very best I've heard my 804's sound is with a tube integrated. But not just any tube integrated - the KR18 BSI from KR Audio. It uses the 300BXLS tubes and puts out about 20 wpc with excellent current drive. This amp drives the 804's to near perfection, with smoother highs, more dynamics, a richer midrange and much better bass than any SS combo I've tried. It makes them into very musical speakers indeed.
I just sold my 804's 2 months ago and moved up to the 803's. I use the Mark Levinson #383. It sounds fantastic!! I use Cardas Golden Ref IC's and speaker wire(bi-wire). This combo to me just sounds right. Like music not Hi-Fi. Peace and Good Listening, Pat.
