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

I took a trip to Colorado and Utah August/September this year. I need to hear gear before I purchase.

One place I stopped by, TMRaudio.com in Eric, Colorado, they sell new and used gear. TMR also has an excellent return policy. They do an awesome job of testing and validating used gear before it is listed.

Many of the stores I visited on that trip, list used gear (like demos with warranties). This is how I find stuff. They also list trade-ins and gear on consignment. You can contact dealers that sell gear you like and let me know what you are looking for.

Just like buying vinyl, you have get down and dirty in the bins to find the hidden gems. I have been looking for the Treo CTs for many years.

I was looking at The Music Room email for some of the gear I heard on my trip. They listed a used Simaudio Moon 700i (SS, 1/3 price) and a used Vandersteen Treo CT (1/2 price). They were listed a week or two apart. Each was purchased the day I saw them, neither goes on sale very often. Simaudio Moon has new gear coming out, someone upgraded, so I was lucky. The Treo CTs are very seldom available used. Both pieces are at my house now.

Thank you TMRaudio.com! (I do not have any relationship with TMR, other than a happy customer.)

Thank you for your comment but just because someone says it sounds good somehow that's supposed to influence me to buy it. that's the oldest marketing trick in the world

I'm not sure how you can choose new speakers unless you can hear them or you trust a dealer because maybe his opinion matters.  It's very very very very difficult to buy speakers. I used to spend  more money get better speakers but that's not true.  

Your original question was about not being able to find quality used amps and preamps. My answer was an attempt to say that simply isn’t the case. I don’t understand your reference to speakers in your response. Theta and Ayre make amps and preamps (among other things) but neither makes speakers.

"I used to spend more money get better speakers but that’s not true."

What does that sentence mean?

The question is based on a false premise.
