Try Joule Electra. Hey that is a great speaker. The best results I achieved was with the Joule Electra OTL amps. A fantastic combination that had realistic instrumental color, huge dynamics both micro and macro, superb midrange and extended high end response. The Joule amps had that magic that helped people feel they were at a concert, not listening to reproduced sound. These amps are rock steady, sound better than the atmasphere products, are built better, and should prove to be more reliable.
