Hi Phaelon,
I beleive a SET circuit would be quite demanding and revealing of the intrinsic characteristics of the output tube. If it sounds good single end I can`t fathom why push-pull should be any different as now the tubes are working as a duo as opposed to solo responsibility of full signal wave propagation. I`ve owned the Shuguang Treasure 300b for well over a year and they are wonderful sounding as well as very reliable. The Full Music 300b SE is also raved about. 6moons has done some very detailed comparisions of various high end 300b tubes including the european brands.
