Power amp Boulder 860

My Int 30a Pass is a delightful integrated but my new Martin Logans need more power and driving capability.

I was offered, unfortunately given the distance without possibility of prior proof, a Boulder 860 finale belonging to the previous series of the famous American brand. In the event I would use as a Virtuoso Ensemble that I have owned for several years and that is giving me a lot of satisfaction.

Beyond the license plate data on the Boulder website, does anyone own it or have you had the opportunity to listen to it? What characteristics does it have?
