Hi Kal - so apparently the research I read about back then has been called into question in the last twenty years at some point? If so, this is honestly the first I have ever heard of it - as I said, I remember it being discussed in multiple studies not as a theory, but as scientifically proven fact. Perhaps they were indeed based on the same original research, but I don't remember it that way. Certainly there are many people in the audio/music industry that believe it. I would be interested in hearing how this was disproven then, if it has been? Or was the research merely deemed unreliable by someone, which is what you seem to be implying, and if so why, if this is easily put in layman's terms? I am certainly no scientist, but the idea does seem to make sense, even if it hasn't actually been proven reliably. Please feel free to send me an email through the audiogon system if that's easier.
