$2500 speaker threshold

Hello everyone,

Recently I was reading the latest edition of Robert Harley's The Complete Guide to High End Audio. In an early chapter he refers to a "significant" disparity in quality between speakers selling for just under $2500 & selling selling for just over $2500. I'd never heard of this before.

I realize that quality is supposed to improve with price, but Harley was clear in stating that the $2500 threshold marked a larger gap in quality than would be seen in other price-point differences. Unfortunately he didn't elaborate on just what made the >2500s better than the <$2500s.

Anyone know what that might be about?
