If the PS Audio Stellar 700M is as great as all the reviewers say....

@n1dr folks are upgrading to the newer and more powerful M1200s. 

I’ve had a Stellar 300.  Very transparent, great tight bass. Needed 100hrs burn in, sounded bad right out of box. For me it was a little edgy with my Cornwalls, but Klipsch can get edgy quickly without a very smooth amp. 700 is supposed to be a little “warmer”.  As far as there being a lot of anything on used market, I think you have to factor in scale of new sales. A large scale maker, like PS Audio sells a lot so they is likely to be more for sale used.  Also, upgrading is a real addiction in this hobby, not really an indication of poor performance, we just alway want something a little better! 

M700 is their least expensive mono blocks and they do sound good, but their bigger brothers like M1200 and BHK 300 are in a different league. People likes PS Audio products often do upgrades and they have generous upgrade program. Therefore many trade-in such as M700 ended up in the used market.

Because PS Audio markets much better and deeper than just about anyone. So people are attracted. More sold, more resold. TMR is their designated dumper for the trade-up people. 

If you do enough homework I think you will answer your own question.

Good luck!

This has been part of my homework.  Thanks to all. I think I have avoided a mistake.
