Followers of the Double Blind Test Dogma want to distill the depth and breadth of Dr. Toole's work down to debating cable switching, music memory, or fast switching speaker platforms. There is so much more Toole work related to the many factors involved in sound reproduction and listening experience. The entirety of his work paints a much more complex and nuanced picture.
Also, one must remember work done by Harman (i.e. double blind testing) involved significant business profit motive. What sound characteristic did the general public consumer prefer? Identify what the masses prefer and you then provide products for the masses. DBT and other snippets from the work of Dr. Toole or Sean Olive have been adopted by a few as the gospel mantra to explain all.
Dr. Toole said it pretty well himself to summarize the complexity, nuances, and pitfalls of the musical listening experience. "Two ears and a brain respond very differently to a complex sound field — and are much more analytical — than an omni-directional mic and analyzer."
