I have two friends, who when they buy used gear, often send it back to manufacturer for inspection, cleaning, calibration, whatever. Makes them feel better, and often not very expensive. Never do it myself.
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
