THX overrated?

[woodman]

Well, My Yamaha RX-V1400 is THX certified and has a THX mode. The remote hs a THX button. This defintely a different sound field from DTS or PLII . Actually I think it's just a variant of EX called "THX surround EX". Here's a link that discusses it. Look about halfway down the page.

If I am confused on this, let me know.

OK ... now I understand the confusion. Yamaha is simply making use of the THX certification (which they've always met, but refused to pay for) as a way to differntiate DD-Surround-EX (so called 6.1 mode) from the more prolific DD-5.1 surround mode that is the standard surround mode in use for HDTV television broadcasting and DVDs.

But in the final analysis, I stand by my previous comment that THX is not a surround sound format at all, but merely a performance certification. Yamaha has always qualified for such certification, but refused to pay LucasFilm their "pound-of-flesh" for the right to put the logo on their equipment. Now, with competition in the A/V receiver marketplace heating up and getting hotter than ever, they've caved in and paid for the right to use the THX logo. As long as they've done that, they're making use of the THX name to try and put forth the idea that it's worth more than it actually is.

OK, I am starting to pick up what your laying down. But, I think (I am at work right now) my receiver has both a DDEX and the THX mode. What's the difference then. They do sound different. I thought after reading the article I linked earlier DDEX and THX surround EX are the same thing. Bare with me, it's starting to sink in.

If THX is anything like ISO 9000 or 13485, I fully respect the THX level of quality. I work for an ISO certified company. It takes allot of work and effort to keep the ISO Quality certification.

Not exactly, at least for home consumer products. The certification is simply ensuring that the products meet certain minimum standards and some specific performance and/or design parameters. ISO's kind of the flip side in that it does not certify the end products, but rather the management, quality control, and decision making processes. With the THX theater alignment program, there are periodic recertifications involved.
