I agree and have always maintained that the quality of the power is just as important. I've heard a couple vintage speaker amps with loads of power sound worse than even an M^3 amp. It's entirely likely that a lot of the powerful speaker amps being used to drive the HE6 with good effect are just high quality amps. Hearing that, folks may then associate the bump in SQ with solely the power.
