Why is used audio equipment so undesirable?

I used to buy good used equipment that was sometimes a few hundred $$$ off the retail price to 1/2 the retail price. Most of these pieces have been sold for sometimes more than what I paid for them to a few hundred $$$ less. Anything new (audio piece, car) will depreciate the minute you bring it home.

As for vintage equipment, been there decades ago but will never go back except for a couple of model separates. I used to own top of the line equipment 45 years ago, have repurchased some of these pieces for secondary/third systems and they just don’t cut it compared to todays technology, except for a couple of pieces which go for many thousands today, then you have to worry about failure rates/parts which are very rare. IMO of course

Just sell it on commission at TMR Audio.They'll even pay shipping to them. Unless it's low end stuff from a big box store. In that case donate it or give it away.

When possible, used is the way to go. It’s a no-brainer. I’ve always gotten a massive discount for gear that looks and performs like it’s brand new from the factory.

First of all, new equipment is generally marked up about 90% so if you get 40% of what you paid for it, that's about all you can expect. 

Second of all as others have said, used equipment is the best value for your dollar. I have a Kenwood receiver made in the late 70's that is still working fine with only a few bulbs replaced and I expect it to last longer than I will. 

I would be happy to help you reduce your inventory

If by any chance you have a decent CD player
