I am an Edge Electronics dealer, so take this as you will, but the NL-10 is a very nice 220 watt amplifier with no solidstate glare and has enough speed to keep up with the microdynamics of any source. We heard it with the B&W N800s and they did quite well, though they were only 3 weeks new and some leeway had to be made for their not being broken in yet.
They really love fat power cables to play at their best, as do all good power amps, so you should probably factor that into your hunt as well... :-)
