How do you deal with absolute polarity?

Among many interesting and surprising things in George Louis’ web site regarding absolute polarity

http://www.absolutepolarity.com

are some letters he received from certain audiophile electronics manufacturers in answer to questions regarding their products and absolute polarity. Here’s one such response (name of manufacturer withheld):

Dear George:

"From my research and development department, they advise. It is a source so as long as both left and right are inverted, then there isn’t an issue. We did this to get better S/N ration performance. Inverting amps are always quieter than non-inverting designs.
Audibly, you can’t tell one from the other, you can only see it on a scope. That is the only way to know one from the other. So why they even check for this, I have no idea because it doesn’t mean anything. The signal is AC which means it swings both positive and negative."

The number is actually 92%, the number stated by George Louis, polarity pundit, whose web site contains a great many audiophile CDs and their polarities. His results are drawn from listening tests. Now, I am not vouching for either his hearing, his results or his numbers but I have to say he certainly makes a very good case. You would have to read his complete explanation for how he arrives at the magic number of 92%. Since there is no Standard for absolute polarity one imagines anything is possible. I have heard estimates for percent of CDs being in reverse polarity ranging from 10% to 50% to 92%.

If your system is determined to be in correct absolute polarity and you don't have a polarity switch, one strategy is to reverse the leads at the speakers so that the system is now in reverse absolute polarity.  Since at least 50% of CDs are in reverse polarity, most notably the audiophile CDs, and perhaps as many as 90% are in reverse polarity, then you will be listening to the majority of your CDs in correct polarity.

The out of phase track on the XLO Test CD will provide proof that the system is either in correct absolute polarity or reverse polarity. When the system is in correct absolute polarity discs that are OOP will sound more diffuse (less focused) and lack bass response, relatively speaking. According to the Polarity Pundant about 90% of audiophile discs are in reverse polarity. 

Here's the whole story,
