The best,IMHO, is OTL amp by Joule-Electra. Nothing come close.
If too expensive, don;t like OTL amp maintance, too much heat etc then Spectron - amplifier designed to deal with reactive load speakers; very powerful and yet etraordinary musical. Can be paired with Joule-Electra latest LA-300ME preamp - no roll-off highs or mushy bass there !
