I didn't really mean thx cert. to be an advantage of recievers

...Am I right in the assertion that THX cert. is just basically a stamp that the device has a fixed 80hz crossover on all channels and has at least some number of watts per channel and probably some kind of distortion or S/N requirements...

Also, don't companies have to pay for the certification? It's just used for a selling point for the uninformed masses at Best-Buy and Tweeter (the latter more-so)

is that the jist of it? or is there something more worth while with it?
