Stan Lipshitz on Absolute Polarity:"Indeed, in a double-blind demonstration, the accuracy score was 100% on the summed 200Hz and 400Hz tones over loudspeakers, and over-all, including musical excerpts, the results on the audibility of the polarity inversion of both loudspeakers represented a confidence of more than 99% in the thesis that acoustic polarity reversal is audible." -- JAES, 9/82
"An effort should be made to standardize the polarities of the whole recording chain.... It also serves as a warning to those who conduct A/B comparisons on audio components without taking into account the possible relative polarity reversals which such components can introduce." -- Wireless World, 5/77
"Differences in components can frequently be greatly reduced, or even eliminated, by assuring that acoustic polarity is maintained when switching from Amplifier A to Amplifier B." -- HFN/RR, 1/78
"I believe that failure to maintain polarity is one of the most serious shortcomings of many A/B tests and one of the main causes of audible differences between components compared in this way." -- The Audio Amateur, 3/78
"Polarity must be taken into account when comparing two components." -- TAA, 4/79
