Also something no one has brought up: the leading High-end companies do not just give their gear to any old dealer. They usually undergo some sort of credit check and many manufacturers will actually visit a dealer to see and hear how their gear sounds!
Not a guarantee of anything though. I went to Dallas when the CLX was there at a dealer in the Truth in Sound Tour to hear it and it was awful. Most of the space was awful and I couldn't see how anyone could get a fair assessment and they had all the name brands.
Later hearing the CLX at other opportunities in a well treated room it was much much better.
