I remember reading articles about this before.It may have been done more in Europe,or some other country overseas. But,from what I remember,some speaker companies put on a demonstration in large auditoriums with great results. Reviewers from magazines may be where I read about it.I get more enjoyment at home myself.When I've gone to listen to a live orchestra,I always seem to get the seats where all the ladies with the fur sit around me.This fur adsorbs all the highs.It makes those live concerts sound lifeless at times.I even tried clothes that have less absorption characteristics,but we can't be seated alone. When they do a good job of recording,their mikes capture a lot of what we miss out on.If we could hear them in an empty auditorium,the outcome would be better for a live performance,at least in my experience.They do sound fantastic when they're getting ready,before the auditorium fills up,but then there is a lot of reflections.There are places with small jazz groups that don't have this problem with the large close crowd,and I can say my system at home gives a fantastic illusion of,you are there. I have no idea on what kind of percentage to put on recorded music, but when they do it right,I would have to say that its fairly high.
