Dom, why a given company does or doesn't certify a specific component, I couldn't say, but I can tell you this:
NOT being THX certified does not necessarily mean that a component is NOT capable of passing the requirements, only that it hasn't.
Nothing in my system is THX, but I doubt it's lacking anything in the sound-quality department. It's more than capable of filling my 16x26-foot room.
There are two THX certification classes: Select and Ultra, the difference being the volume of the theater space.
