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

So dealers take my trade-in and sell it to a company specializing in the sale of used gear? So that may explain things.

How does anyone make money selling new equipment with all this complexity? Unless the margins are greater than 50%.

It seems with all the solid state gear we're saturating a limited market with used gear since this stuff lasts for Long time. Eventually the market wouldn't be able to handle new gear as easily. And we know that new products introductions are mostly the same as old products only in new packaging.

cause good quality gear is manufactured in much smaller quantities!

question is too broad. specifying what exactly you’re looking for would help to share some findings.

please define "better quality used gear"

"So dealers take my trade-in and sell it to a company specializing in the sale of used gear? So that may explain things."

What would it explain as it would still get to market and be availble for those seeking it.  

"It seems with all the solid state gear we're saturating a limited market with used gear since this stuff lasts for Long time."

And yet here you have created a thread whinning about the lack of used gear for you to find. Which is it?

A lot of life-changing events have happened since I started this epic thread so long ago. Adopted a dog and have become a philatelist.

Being a philatelist is a very very expensive hobby too. So much to learn. They got this one tiny square piece of paper called a stamp with perforations all around it with an upside down airplane in the middle. It’s an air mail stamp called the Jenny, the inverted Jenny. It’s very rare because it was a printing error and looks really cool and there aren’t too many of them. One recently sold for $2 million. How many $2 million speakers do you know of?

I also learned that you only get your image on a stamp if you’re dead.
In 50 years we may see Oprah gracing mail as it travels across the country.

I haven’t decided what my specialty will be yet. I like older US issues from the 1800s. They don’t make them like they used to. Also like historical covers and cancellations of the older variety can be very collectible. They used to cancel things by hand early on.

Curiously it’s very similar to audio gear. While mint or new stamps are more valuable used stamps can be very desirable and extremely valuable. And they have all kinds of condition issues that need to be evaluated.
