Lots of pretty words!
I have heard a number of different speakers in the 100K - 500K range at Audio Shows. The electronics and source components were at lest that much again. Sounded great! Did they sound better than systems at less than a tenth the cost? Not convinced. Would be interesting to take a 50K system which had been fully tweaked, and match it up to a
million $$$ plus system and do a true double blindfold audition. Probably will never happen, but in that scenario I wouldn't put my money on the 'high priced spread'.
