I’ve been baffled by audio gear pricing for years, so you are not alone. I have no doubt that some (or many) listings are because a spouse has demanded to "get rid of all your extra junk not being used". Sellers post an item at a ridiculous price, knowing it won’t sell at that price and not even entertaining fair offers, just so they can say, "I tried selling it, Honey!".
I posed a question in a post a while back regarding a turntable that must have been listed 4 or 5 times over a year. The price never changed and I asked at least 6 questions that went unanswered. Same with a Sota table I’ve seen listed for what seems like a year -- without a change in the $1,500 asking price. Tell me you don’t want to sell something without telling me you don’t want to sell something. LOL!
Also, you’ll find Audiophiles have a "overly optimistic" opinion of what used 5 to 10 year gear is worth. While post-pandemic isn’t the best example to use, but in "normal years", buy a new automobile at the dealer, drive it off the lot, and bring it back 6 months later to resale. You think you’re going to get 80% or more of the original purchase price back? Again, discount the current bizarre 2 year period we’ve seen -- car inventory will bounce back to normal levels within the next 2 years.
Good luck on the purchase attempts. I hope you have better luck than I've had. My best purchases this year have been through building Social Media relationships. I've purchased a pristine Audio Research SP17 with phono stage for $1,200; a McIntosh MC-225 built in 1963 that is nearly flawless with original McIntosh branded tubes-- just a little lettering on the "Spec Edge" is rubbed off -- for $2,500; and a mint condition Dennis Had Inspire 45 Fire Bottle amp and LP3.1 preamp with new Emission Labs tubes for $2,200.
