I have had Matrix 804's and they sounded great with Levinson or Joule Electra. I think they work better with solid state because of some dips in impedence which makes them hard to drive for tubes. As impedence dips, SS puts out more power. Most tubes put out less. (I think I am right, but I am no expert). I sold the B&W after I got the Joule and bought Merlins. Good luck.
