Right, and people routinely hear differences in cables, power cords, etc. Doesn't mean those differences actually exist.
Controlled tests between the codecs done by 5.1 Entertainment, Warner Home Video, Home Theater Mag, What Hi-Fi magazine, Home Cinema Choice magazine, etc., were
all unable to reliably pick DD apart from DTS (let alone demonstrate a consistent listener preference).
Had somebody (anybody) been able to establish DTS's superiority over DD, it would not only have been news but been flaunted by DTS in all their marketing material. But in the decade that DTS has been out, they have never
ever been able to point to a single controlled listening test that supports what you're claiming. That's a fact.
You can place your "informal testing" over the testing of the magazines, movie studios and music labels, but that doesn't establish a difference that formal testing has never been able to demonstrate.
