best used amp around $2000 for B&W N802s


I am looking for a used amp in the $2000.00 range to power B&W N802. I here they take alot of watts to run, but i have also been told that 100 class a watts are better than 200 a/b watts. as most of you can tell i am new to this and could use some advice.

Thanks

I have a Threshold 400 model A amp that puts out the same 100wpc that the mark levinson 331 does. Is there much difference between the two?

I have Odyssey Extreme Monos and am absolutely delighted with the sound. Really feel as though I stumbled onto a great product, and did purchase used at Audiogon, but seller lived in adjoining city, so able to audition (!). Only quirk is that one channel occasionally (not often, and not loud, but audible) lets out some static sounding stuff, but in general the noise floor is very low. I am REEEEEEALLY picky, and even I don't think it's worth the bother to send them back to Klaus. In fact, when I upgrade my system, it will be with an Odyssey Tempest Extreme preamp (if I can get it to fit into our tiny available cabinet space), Groneberg (sp?) cables, and possibly the Odyssey Lorelei speakers. Also plan a DAC, possibly the Benchmark.
Despite what people think 802's are rated at 91db sensitivity. You do not need a shitload of power for these speakers.
