So this is left over from the original Sherwood design? Interesting that Outlaw kept it in.

Based on what I've heard and read, the THX branding is more of a marketing ploy. Consumers Digest's Best Buy pogram sounds similar. If a product that CD reviewed earns a "Best Buy" cerification, the manufacturer is offered a package to display its logo as well as the rights to the article in the mfr's advertising. It cost about $1,000 a year to maintain. There was a coalation between the winners and how much they advertised in CD. (I used to work there.Shhhh).

Thanks for the background
