I'm not going to lambast THX. I think their efforts have helped much more than hurt, but it is, after all, a commercial venture. A few comments ...

There are some 'THX certified' theaters that, if I were a 'certified THX certifier,' I would yank the theater's cert for the way it sounds in there. But perhaps all the specs are met, and so the THX cert stays in place.

As to the 950, don't sweat the lack of THX cert. Prior to the 950 I was using a THX-certified Onkyo 'Ampli-tuner.' The 950/770 is a noticable improvement.
