An experience I had with a seller.

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

I do like threads like this every now n then as they provide insights on sellers to shy away from and those who might take the high road.  

@tomic601   Agreed. When I called Ayre the guy that looked up the serial number was surprisingly pleasant and helpful. Not sure if Ayre is still that customer orientated.

As a seller (in spurts), it's the part of this hobby I enjoy least. Sometimes the tire kickers and silly questions simply get to me, and at those times I demonstrate zero patience for anything other than "are we doing business here, or not?". I take great pains to list & picture all relevant details, and feedback history tells how the transaction will go once money changes hands - so if you really need to volley with me, then quite simply YOU DON'T WANT WHAT I'M SELLING :) I guarantee I'm losing money on every sale; I don't need to lose undue time as well. 

That said, some of the genuine hobbyist here are rather pleasant to chat with (once any business objectives have been quickly sorted), and if I do post incorrect information, I'll happily & gratefully take accurate corrections. So the guy you mention was a dick for that. But I also totally get frustration on the seller's end.
