9rw, you are right the John Dunlavy knew ALOT about speaker design and some really love his speakers. He also basically said that those that can here differences between speaker cables are hallucinating (other than the impact of guage). That essay he wrote wasn't popular with cable manufacturers. Do you agree with him? You can Google his essay on "differences" between cable. quite interesting.
I, by the way, have heard improvement through Bobby's incremtal improvements. Perfecting the basic design over years is on reason the speaker is so well "sorted out" and for many owners, in some ways, the best speaker ever made. Which is not the same as saying it will be everyone's favourite speaker. But it is a speaker that needs to be taken seriously when looking for the best sound in the home.
