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!
If the PS Audio Stellar 700M is as great as all the reviewers say....
...why are there so many used ones for sale?
