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

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.

If you’re not considering the ratio of total units sold to for sale used, then you still have more homework to do. It might be that this model is below average even though there are a lot for sale.

before PS went to manufacturer direct only sales last, many of their products were available from their large online dealers at 30-45% off...now it's all list price
