An item that’s traded numerous times can indicate there’s something wrong with it.
For instance, there’s a Bedini amp that’s been repeatedly bought and sold, same serial number; it’s been bouncing around for a few years now.
Otherwise, the number of owners isn’t as important as whether it has been recapped or repaired.
Any indication of lying, or even of glossing over the truth, I’m gone.
I find with used equipment, in general, if it’s in fine condition and the seller describes it in detail as from one audiophile to another, it has not fallen into the hands of an owner or owners who don’t know what it is, and don’t respect it.
Also, never allow hope, or wishful thinking, or a good deal, or a rare opportunity, cloud your intuition.
The few times I’ve been disappointed in a used purchase have always in the final analysis come down to my going against my intuition.
