I have Krell FPB200c amp run to B&W N802 speakers. I have auditioned Audioquest, Mit, and have purchased Transparent audio Reference with the xl technology. I love the sound and hate the price of that stuff. For me, I could not be happy with any level lower than the reference level. I would also suggest bi-wire cables for these speakers. Thirdly, I run a subwoofer which I route through a seperate preamp for remote controlled volume control and it seems to work slick for setting exact low level foundation to the music.
