I"m familiar with that thread.
I fully respect the work done by Toole et al on correlating speaker design with general listener preferences. Problem for me is the personal applicability. I've auditioned the speakers designed via that research - e.g. Revel - and found them to be extremely competent, and to "sound" like the measure as much as the measurements can predict. But it hasn't predicted this "sounds right to me" specific timbral quality I'm talking about. In other words, the Revel speakers just never had the "it" factor in their voice that made me immediately feel 'yes, that's like the real thing.'
(It would be fascinating to undertake the Harman Kardon blind tests. Statistically I'd have to expect that I would actually choose a Revel speaker over ones I *think* I like more in sighted tests. Which is an interesting conundrum for a buyer - buy what sounded better under blind conditions, or what pleased you more under sighted conditions in which you'll actually listen?).
