I'm not full of disinformation, nor do I care if Onkyo measures better than Denon, etc. Those differences will be small when everything is taken into consideration.
A THX receiver is not just rated to put out a certain amount of power. A THX receiver has the THX algorithms. They make a HUGE difference, more so than any distortion, frequency, and power measurements. The THX algorithms EQ the signal in a major way, they add timber, etc.
ALL high budget movies were mixed with these THX algorithms. As a matter of fact, 99.99% (within the past 20 years) of ALL movies have been mixed using THX algorithms. Disney, Fox, Lucasfilm, Rydstrom, and the list goes on and on.
If you're watching movies without a THX processor, than you're not hearing them anywhere even close to how they were mixed at the studio.
It surprises me, that well established members, on a very technical forum would argue against this. You all seek hundreds of tests and measurements, high quality parts, yet without the THX algorithms, when it comes to movies, everything else becomes 100% meaningless.
What's the point of having state of the art equipment if you cannot listen to the original artist's intent?
