@ charles1dad, you are the man!, you hit the nail on the head when no one else could, when I said tube magic!, Tone, bloom,and 3- dimensionality is what I am emphasising here!, It is difficult to express what I am saying gentleman, I am sorry, bear with me, How would all of you here compair purity audio preamps to atmas-phere preamps?, I have a problem with 32 volts out-put, although Ralph has gain controls outside of the signal, I want to know if that is a control to the output volts, My amp is fully driven at 3.58 volts!, clipping is 18 volts, an explosion!, I am reffering to the m-1 preamp. merry christmas to all of you!
