@medium_grade Thanks for the recommendation and the eloquent description. I was imagining a Sumo wrestler in a tutu doing classical ballet! ;-)
As to the Elekit TU-8600, stereophile had a raving review about it as well.
As I was looking, I could only find these amps on eBay (either built or as kit) but they all seemed to be located in Japan and require 100V mains?
