The only time I have heard High end gear was a visit to AXPONA. In a very large room on the ground floor. Setup of MBL speakers and associated components including mono block amplifiers the size of a small deep freezers. Can't remember all of the different brands represented. Sound was good but not what it would be in a properly sized and treated room. Not the best way to experience what a million dollars could do. That was the price that was quoted.
I know and appreciate the design manufacturing effort that goes into the product. High end gear is nice but I wouldn't spend for the high end even if I had the extra cabbage....
