Yeap, Pass, Classe, McIntosh are generally liked with B&W.
I own 804S and back 3 years ago I auditioned Classe, McIntosh solid state and McIntosh tubed MC275 and went with it. I just love tubes with the 804S. You do miss some slam, but you gain oh so much. Of course, that was me with my ears!
Cables? I suggest you postpone that one until you get an amp, learn to know it, and only then look for cables that will match the speaker/amp combo well. I got that advice 3 years ago and now I'm about to buy speaker cables!
