An experience I had with a seller.

About 6 years ago I started a complete system upgrade process. The component in question was an Ayre K-1xe preamplifier. My question was the manufacturing date and was it a factory Evolution series? Despite his high volume 100% feedback rate the serial numbers seemed off. I called Ayre and it was verified the unit was 6 years older than claimed and was not an original Evolution model. I immediately E-mailed him and never a response. My point is buying used gear is similar to playing Russian Roulette you have no idea of multiple owners where the unit has been stored or if any slight modifications were made. This proves to me that even  "respected sellers" can outright lie. 

One of the few benefits of getting older is that I was there in previous periods of audio history. Thus, I can honestly correct or confirm history- yes, the Ampzilla was originally marketed as a kit, for example. Or that Dahlquist DQ10 speakers were not originally mirror imaged with the drivers. 

The sellers response indicated that he had no interest in being honest with customers, and that is disturbing 
 

what was sellers response? Have you seen the entire correspondence to draw this conclusion?

I had people with zero intent to buy reach out to me on USAM to tell me they didn’t like the price I set for the item. They were, as a rule, members with no feedback or very little feedback buying and selling low fi AVR type items under $1000. My listing was for Pass Labs amps and preamps, high end Nordost cables.
My response was - make me an offer and we can talk. But if you are just price policing, go bother someone else.
Don’t be a busybody. And you won’t have to come here looking for sympathy 

I differ. OP sought to help a seller clarify or correct a misstatement of facts in a listing. This is a practice encouraged by some listing sites. Asking price is not the issue here
