Here's a unique one. DivaBe's by JM Lab. Fairly easy to drive, and a good match with tubes. I owned 3.5s and for everything the dealer had.. (krell, audio research, theta, Ayre) the only thing that drove them decently was a FPB300, which, come to think of it, used on audiogon might be in your ballpark.
Cheers,
