I have seen comments on the board about evaluating amps only after they have a chance to "burn in".
Can someone tell me why a solid state amp or even a tube unit would have to be burned in to achieve optimum performance.
I can understand this process somewhat wtih headphones because there are moving parts and maybe with tube emission because there is the heat factor.
I cannot explain it, but most audio gear that I have used changes in sound very slightly after it has been broken in (anywhere from 10-300 hours.) It is especially obvious with tube gear and speakers, but even solid state gear and cables can change in sound after break in. This has been my experience, but I cannot explain it.
