Thank you. Good posts.
Sorry, my initial post was not very clear. My older preamp was not sent to Lamm for inspection, and I do not particularly suspect it has problem. I have wondered, though, if it is supposed to sound better. I am just too un-technical to know if that is a reasonable stance, that parameters may have drifted off or something. Along with the many classifieds advertising equipment that was just checked out by the respective manufacturer, I began to wonder what others' experiences have been.
