I was speaking with some representatives from Musical Fidelity at the stereo show in NYC in May and they were demonstrating their amplifiers with Thiel speakers. Their claim was that this pairing was more than just a show pairing, but rather they felt that their amps sounded best with Thiel speakers. In fact, they went on to say that they own each others' products. I am a MF fan and own the MF CDPRE24 and the A300 power amp (paired with non-Thiel speakers though). I must admit, I really enjoyed the MF pairing with the Thiels. You may wish to investigate MF's A3.2 and/or 308 integrated amps ... though they are both solid state amps.
