The ST1000-P does not smoke a TX950. It is worse in every measure I can find, and is made from lower quality components. I'm glad you're happy with it, but you'd honestly be better off with the HX850 (or the TX950, and I am unconvinced about your compatibility proclamations - you should be happy with the exchange you got though. The HX850 is superior to the TX950 in basically every way).
