It's funny as myself being a participant of WBF it usually seems to me that all of the global "big time" systems that exist are known and discussed.If Ked hasn't visited it, it doesn't exist.
THEN on the other side of my existence being in business for 20 years in NYC with literally hundreds of customers and 50+ customers, over the years, with $300K+ systems there are maybe <10 of these customers that are literally on ANY audio forum, more less WBF.
Add the who knows how many audio stores now and over the years on the globe with probably similar statistics and it would seem that we "think" we know about all the big systems that exist, but I think that "thinking" is highly questionable. imho.
