Geoffkaik...Dunlavy most certainly was not deaf and designed some of the best speakers ever offered to the public. I talked to him on multiple occasions and he felt very strongly that past a certain threshold, high-end cable manufactures were just playing around with differences that were tradeoffs at best. His listening tests almost always ended with very little correlation of cost to discernable performance improvements. In fact, most listeners couldn't even tell their own cable from anyone else's cable in the test group. I suppose I should also mention that when it came to room acoustics and speaker placement (and such), he was very passionate about those topics and wrote a number of 'white papers' which have become something of a standard in the industry. In fact, if you go to one of your local high-end audio shops and talk about these kind of things, it's likely the advice that will be given will be a rehash of Dunlay's empirical findings, without the salesperson even knowing the source.
