"You ask, "How does research not be valid when it is out of research and engineering that you're listening to good sounding equipment these days?" I have no idea what this confused statement means or what it has to do with double blind testing, which as far as I know has never resulted in any audio designs."
You do realize massive hours of testing (including blinded trials) went into the design and selection of PCM and bit-rates related to the CD technology in the early 80's right? Some of the most respected firms like Weiss regularly uses blinded testing to validate designs as well.
Show me some reasonable publication which states that double blind testing is invalid. Here's IMO a nice one from back in 1981 on parameters for "meaningful subjective tests". I don't see any major problems with their rationale, including item 4:
