Amplifier Recommendation for B&W Nautilis 804

I have been very happy with Cary SLP 2002 & V12 driving my N804s in triode @50wpc in my 11'x13'room. N804s are made for small rooms like mine. For tweaks, remove speaker and tweeter covers. Tweeter covers are magnetic attached. The Sound Anchor stands tighten bass.

Jeff,
I agree with Bombaywalla on Pass Labs amps. I had N802's and drove them with a Pass X250. It was a great match. I also had N804's prior to getting the N802's. I drove the N804's with a Krell FPB200 and a McCormack DNA2. I was never disappointed in the bass of these amps with the N804's, but the Pass X250/N802 combo was very special from top to bottom.

How 'bout just buying a new house with better acoustics? Cheaper than upgrades..? ;-)

A common complaint about the B&W 804 Nautilus is their lack of weight.

A solution to this is to have them sit on granites stands made by HNE. They cost around US$500 here in the UK but they make a huge difference to bass weight and overall integration of bass with the mids. Without the stands, I find the 804s lacking bass weight and its bass timing somewhat odd. I certainly think that these stands are essential for the 804Ns to sound good.

Compared to the N803, the N804's bass is loose and flabby. It's a problem inherent in the speaker -- even when it *is* properly amplified.
Before spending a lot of money on accessories, I would trade up to the N803's, which will always have more weight and more satisfying bass. Or, I would take a look at some Sonus Faber Grand Piano Homes, which,
IMO, sound better than N804's, cost a little less, and are a lot more efficient -- meaning -- it won't be nearly so hard to drive them.
