I've had some problems like this, once an amplifier seemed to have a thermal issue, it would turn on initially, but once warmed up if it shut down, it would no longer turn on. I took it back and gave full refund.
Another time I sent a speaker to Canada and when it arrived it had a blown driver. After some communication, the buyer offered to split the cost of the driver. I agreed, but since I sold a $3,000 pair of Linn 5140's for $800, a VERY fair price especially when I sold them (two years ago) the extra couple hundred dollars meant I basically gave them to him. Had I know of the issue, I would have just donated them to good will.... would have been more productive for me, but in the end he got the speakers he wanted and I got, well not much but that's how it goes some times.
I once bought some speakers that were rated 9/10, but when they came they barely made 8, really a 7. The seller gave me cash back, to me that was fine.
I guess what I'm saying is it all comes down to the two involved in the deal and whow reasonable and flexible they are, and what you both can live with.
