Amplifier Recommendation for B&W Nautilis 804


I currently have N804's driven by Musical Fidelity a3CR amp and preamp. While I like the sound, I am finding the combo a bit lacking in weight, particularly in the bottom end. I'd like to see a little more punch in the music without losing detail that the a3 is known for. The A3cr is 125 watts into 8 ohms, and the 804's are rated from 50-200 watts into 8 ohms. I would spend up to 3000 for a noticable improvement.

Does anyone have a similar setup and/or any suggestions? Thanks.

Bombaywalla, great reply.

"So, whatever you choose make sure that it has lots of lower volume level current sourcing capability. You are probably not going to exceed 50W from the amp so make sure that it can source ample current at that lower level."

How do you know an amp meets this?
Jeff,
You got tons of good feedback. I have owned N805's, currently own N804's and am familiar with two more systems with N804's and N803's.
With N8XX speakers, wimpy amps need not apply, period! Even the N805's that I used to own didn't wake up until I put a gutsy amplifier on them (a Krell).
Also, go immediately to the Sound Anchor website. Do not pass go, do not collect $200. Instead, spend $225 and get a pair of their dedicated speaker stands. I did. The other three guys that I know who own N804's and N803's heard mine and now have these stands. All four of us got a substantial improvement. Money very well spent!
Best of luck and have fun.

I got a good deal on used N804s one time. They had a beautiful cabinet and all but my new Paradigm Reference 100.2s have a much more pleasing sound quality. B&W lack weight - just as you said. I am glad I got rid of the 804s. Arthur
Brianmgrarcom,

Unfortunately, there is no standard procedure to determine this! Nothing in the spec will show you this either!

It will be determined by the listener him/herself. If the store you are auditioning the B&W has a number of amp brands try on the smaller ones & then some of the bigger ones. You will hear the sound diff. The bigger amps will lend more authority & weight to the sound + they will sound "right".

All these terms are fuzzy & each person's ear is diff. so the definition of "authority", "right" is all subjective & I cannot exactly define these for you. I can tell you that the bigger amps sound much better w/ B&W.

Sorry for such a non-commital answer! It's very subjective.
I agree with you Bombay, the Nautilus speaker do need good clean power and a lot of it. I will also second, or third, the Sound Anchor stands, big difference.
