Technical and scientific discussion of amps, cables and other topics.

"It's not up to me to prove reviewers can't hear the huge differences." LOL! You made the assertion...

...that they couldn't. Now it's up to *me*, to prove they can? Again, LOL!

"Wine experts comply with these requirements all the time." Very rarely, actually -- only in contests (of which there are few) and in the examination for MW (of whom there are few). Suggest you stick to your own expertise.

Clark: "But numerous DBTs (or better) have proven polarity's undeniable audibility -- why don't you believe the DBTs?"

EBM: "Now you're changing the subject."

Guy, you're the one brought it up! Geez Luiz. You only wanted me to do all over again, what has already been firmly established.

And on it goes:

"The signal has to have a fair amount of asymmetry." Yep. Not like test tones, rather like, oh, musical instruments!

"On most material and systems, most of the time, there was no evidence of audibility." A total mischaracterization! My own tests established a 99% confidence on musical examples alone, and John Atkinson's got IIRC 95%; both were published. And Stan Lipshitz reported 95% as well, on tests involving both tone bursts and music, not to mention that he was a fierce partisan of absolute polarity, as was Prof. Richard Heyser.

"None of those tests prove anything like what you claim in 'The Wood Effect'." I made few claims of my own in that book; it was a compendium of, and analysis of, other people's claims and tests. Interestingly, of the some eighty quotations I found in the literature pre-1988, only one disacknowledged polarity, and he was Sam Burwen, a stalwart BAS member!

"I notice you didn't accept my invitation, though, and didn't address the stamped-vs-CD-R issue at all." The invitation was for an experiment fraught with error, as was the one in the M&M paper, so no, thank you. I wasn't aware that you were also proposing some "stamped-vs-CD-R" sort of thing as well, and upon review I don't seem to see it.
