I sold my A-6000 for lower wattage single ended triodes - all you describe is regained. Parallel circuits are difficult to engineer and that is the trade off. But the A-6000 is far superior to push-pull - in my exceedingly subjective opinion.
300B Tube Amps with 15/16 Watts Per Channel?
Felix Audio makes the dual 300B amp "Lybra"--are there any other manufacturers of that gear?.Does anyone have experience using two each 300B tube amps modified to be two monoblocks with 15/16 watts output power each? If yes, did you hear any difference in the exquisite 300B sound other than more power? All experiences and thoughts appreciated. (Yes, expense is already noted)
