I own these amps - paired right now with a Luxman C900u pre and Dynaudio Heritage Specials. Great amps. The dual differential design to remove residual distortion seems much in line with what Ralph Karsten has been saying about the philosophy driving design of his new class D products. Of course, the AVA amps are class AB, running class A for the first 20 watts or so. Amazing little boxes that run pretty cool for what they are.
