Manufacturer checkups


This question is in reference to an older preamp I recently purchased with which I have had no prior experience. Some classifieds state the item was recently check out by the manufacturer and given a "clean bill of health". With an older item that has no functional or visual problems and no obvious sonic deficits, is getting that item checked out worth while?
Thanks

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.
