Despite the high sensitivity of the Klipsch horns, the large woofers REQUIRE high power.
While I have a pair of AtmaSphere OTL amps, I will say I have tried the Zero autoformers in my system, and they really bleached out the sound, and robbed the Atmas of what they do so well. The end result was clear and fast and sterile, and, well... it was if they became a solid state amp.
I will agree that an 845 based tube amp will also be a great suggestion. The ASL 1009 I have heard combined incredible slam and lovely sonics.
