Why isn't better quality used gear being made available?

Ever wonder what happens to all the used gear being returned to dealers. They take trade-ins all the time and yet never seem to have anything available for sale used.  It's a quandary.  Maybe the manufacturers agree to take it back in some crazy financial maneuver to get it off the market. Clearly they much prefer to sell a brand new item and if the channel is clogged with used stuff the manufacturers suffer.

Okay, if you were already scratching your head about this thing being sketchy at the start, here we go off the deep end.  Why am I even here???

OP… “Maybe the manufacturers agree to take it back in some crazy financial maneuver to get it off the market.”

Ok, now that is a crazy conspiracy theory. My dealer takes trade-ins and sells them to a company that assesses and then either sells them on-line or to a reseller. There is not a high end company that could afford to do what you suggest. Some offer their own trade-in policies to do what you say, but they have very tight controls on it and limited payback.

I recently bought Dynaudio Heritage Specials. It knew from the reviews I’d like them, even better than I expected. 

in order for you to buy someones used equip, they have to buy new equip.
in this economy, less people can afford to buy new and are making do with what they have.

I'm sorry, but what a stupid post! If you can't afford the product new and it's not available used, move on! Your assumptions demonstrate you don't belong looking for what you say you are.
