If the debate remains civil, it can add credibility to this place.

Having spent several decades engineering electronic/electrical devices, I have yet to see a scientific device that can measure things like -sibilance, gleem, sparkle, neutrality, impact, brightness, forwardness, and many other terms that are commonplace on this board. You can relate measurements to ideas, that is not in debate here.

Having said that, as I have said many times, you should listen, utiltize any measurements that exist, read reviews from "experts" and non experts - then make your decision.
