Wow... why does Everything need to be about Absolutism? So... the YouTube audio of a Demo'd item is not the Be All and End All. I am convinced most people who are Audiogon participants are aware of the technical limitations on display there. Is it So totally egregious as to be important enough to publicly denounce the attempt to demonstate a product/system (to total strangers) and go on and on about it? Is not a Taste better than a Whiff?
I'd expect the Absolute Truth attitude from the patrons of a (Psuedo) Scientific Site or somewhere that everything gets reduced to Numbers, Ones and Zeros, graphs and measurements...Hmmmm
No disrespect intended, but I don't understand your point or who/what it is directed to/at.
