Any Herron M1A amp early impressions out there?

Keith Herron's recent release of the M1A amp is a great development IMO. No wasted energy/funds to hand cast, or sculpt of titanium the monoblock amp cases, but none better than the M1A, I know of in producing music's pure, exciting wonder. My Herron 3A pre was GREAT with my prev., 9K list amp, but the optimal, exact match to the pre, is, of course the Herron M1A amp. Any experience of others appreciated. System components include Sony 5400/Modwright Truth SACD player, Shunyata Python/ Kimber Select silver ICs and Acoustic Zen spker cables- Satori 8,' tri wired.
