I have the BH2's as well, and am on a similar search for amps. I am presently driving them with 100w Kora tube amps. They are pretty highly reguarded and rich sounding, but I am seeking more, or maybe a bit less... I have been focused on finding the right SET amps rated somewhere around 25 to 50 watts. The Tom Evans gear, producing exquisitly quiet background should be a nice match with a SET. I have taken to playing the BH2's at lower volume and find that they are capable of getting every bit of the magic across the room to my ears.
