"Excellent, superb, a tour-de-force."
My September 1988 review is reprinted at www.stereophile.com/asweseeit/988awsi/index1.html.
Scroll down the page to the section on Absolute Phase.

From the Stereophile review by JA:"Work by Stanley Lipshitz in the late '70s (footnote 9), using carefully organized double-blind testing, confirmed that a reversal of absolute signal polarity will be subtly audible on music to a 99% confidence limit! (Indeed, it is one of the few things that can be reliably detected with double-blind testing.)"
This statement is just... false. That's not what Lipshitz demonstrated - he showed that absolute phase was audible with 99% confidence, but using test tones (which everyone can hear the difference on) and musical selections (which evidently no one could hear the difference on). Combining data with 100% success with data with 50% success gives a very high confidence that there's an effect if you do enough trials, and that's what happened there.
