Rakuennow - Being an engineer causes me to always wonder and try to understand things, but I certainly don't claim to understand vibrations. In fact, I switched from mechanic engineering to civil engineering after two weeks in feedback and controls which preceeded vibrations. It was beyond my ability, at least in a finite amount of time.
Having said that, the Sort Kones give the vibrations an exit path from the equipment, but I'm not sure how to make it "fit" exactly with their description. Sometimes audio marketing uses pseudo science to make things sound a lot more impressive than a simple explaination could, but that doesn't mean that the product works any better or worse. I think the goal is to make the explaination beyond the vast majority so that it unlikely that anyone would debunk their story.
My friend stopped by tonight and confirmed that he could hear a difference with the Sort Kones, but it isn't such a significant change that he wasn't wishing for two identical systems to do an immediate A/B comparison.
He was listening to my new Mr. Paganini SACD and commented on hearing the violinist moving relative to the mic as he played. He said it was something that he was used to hearing live (i.e. change in sound with the movement), but not on a stereo system. I'd never hear this which is why I like him to listen to my new toys and provide an opinion.
