I would expect small differences to be more difficult to perceive in surround, based on previous psychoacoustics work (see Floyd Toole's book)
But Lavorgna's article has basic flaws. His 'blind test' was inadequately blinded, and apparently there was no attempt to confirm levels were matched. And presto, higher numbrs = better sound. Audiophile preconceptions confirmed again! He also takes the Meridian quote about Redbook being 'inadequate' out of context. And he fails to mention that the Meridian white paper contains zero, nada, no listening test data. As a historical sidenote, when that paper appeared in JAES, it prompted as strong critical rejoinder from other AES notables in the digital audio realm, in the letters-to-the-editor section, which in turn prompted the famous Meyer & Moran DSD vs Redbook work.

This is an interesting read. He does something I never do -- compare his audio collection in 2-channel listening. Do you think his observations also apply to surround sound?
Enjoy!
