I just bought some B&W 802 Matrix Series 3N (whew!) speakers.
I've read and been told repeatedly that they need LOTS of power. I am very curious - how much is "LOTS"?

So I've been shopping, but am not familiar with most of the audiophile-quality brands. Price is a real concern so I'd like to get an integrated amp to save money, although one alternative would be to drive a power amp with my NAD receiver's pre-amp outputs. At least one dealer said this would be OK as a "temporary" (i.e. marginal) solution until I could afford a decent pre-amp. Here's what I've considered:

1) Rotel RA-1070 (100WPC) recommended by the B&W dealer (B&W and Rotel share the same distributor, so this recommendation has to considered in that light)
2) NAD 218THX (225WPC) power amp only - $1200?

Stereophile liked these integrated amps, all in the $1500-1700 range, which would be my upper limit:
4) Musical Fidelity A3.2 (120WPC)
5) Naim Nait 5
6) Simaudio Moon i-3
7) Talk Audio Cyclone 2.1

I realize this is an open ended question, but if anyone is familiar with the B&W's or any of these amps, or has a favorite amp to recommend in the <$2K price, I would like to hear it.

I didn't mention Adcom, which is what my friend used to drive these. She was VERY happy with the combination. She couldn't remember the model # or wattage, and had already sold the amp by the time I learned of the speakers.

I forgot to mention, I have already tried powering these speakers with two combinations: 1) my 15 yr-old NAD 7250 receiver (50WPC) and 2) an Adcom GFA-535 power amp (60WPC?), driven by the NADs preamp-out. Neither combination blew away my Vandersteins (model 2). They were better, but to justify throwing down $1700 for an amp, I want them to be much better. And I didn't get much improvement in the sound stage or imaging (if I'm describing this right?), which I really expected. The Vandersteens are not great in imaging, in my opinion, but they are very smooth and easy to listen to. Dealers tell me the B&W's bass will be impressive with a good amp, much better than the Vandersteens.
