Atmasphere, the solid state phono pre never got shut off for the two weeks I had it. I had an ss amp once that took forever to break in, probably in the hundreds of hours. I've often wondered if the same can be expected from ss preamps. Thanks for the suggestion on sticking with triode signal tubes. I don't think throwing out the baby with the proverbial bath water would be right. Not to discount ss but a 180 about face is probably too extreme of an unknown. I see your point about closer to source upstream stuff. But, Isnt it just as likely downstream areas can mask things as well. It's gonna be interesting to hear what changing from the Shuguang's to the EML does. Thanks for your input.
