That is a misleading statement. There is no question that class A designs are less efficient than AB or switching designs, but even then the efficiency typically runs about 30% - with some better than that. I think you'll find that maximum consumption for most Krell designs occurs at very low impedances like 2 ohms where the output is much higher than the nominal 8 ohm rating. Chances are the amp puts out closer to 800 watts under those circumstances. Take at look at their current SOTA product, the Evolution One. It is rated at 450 watts and has a maximum consumption of 3600 watts. But wait, that rating is at 8 ohms. At 2 ohms, it produces 1800 watts class A. If your design is truly only 8% efficient, then clearly D'Agostino has learned quite a bit in the past twenty years.

Would you provide an illustration? My NAD AV receiver is rated at 600 watts total and consumes 840 watts at maximum. 71% efficiency is quite typical for AB designs. And that is for all six channels - where in typical real world cases, the rear channels don't require full output. I would not, however, use this amp to drive challenging loads either of the extreme low impedance variety like yours or the equally brutal reactive load of my electrostats.
