I have driven my BE-10 with Parasound Halo A21, Pass Labs XA160, and now Ayre MXR. For my tastes, the Ayre really takes advantage of the Usher transparency, dynamics, and detail. I felt that both the HAlo and Pass was a bit too slow and veiled. Of course all of this is based on my personal tastes. I love listening to strings (piano, guitar) and female vocals. With the combo I have now, I not heard strings sound more realistic and vocals more clear.
Regarding the BE-20, I say you only need that if you a very large room or want to use these speakers in an HT setup. I find the BE-10 to be more than adequate in terms of bass and its ability to move air.
Good luck!
