The booklet The Wood Effect was written by Clark Johnsen. If you do a search you will find a number of sources that discuss this topic. I had met Clark a number of times at audio shows as he made it a point of coming to our room to hang out. He also always made a point of saying that if your ears were not sensitive to absolute phase in recordings that you should consider yourself very fortunate.

Clark Johnsen has written a lot of pieces about absolute phase and polarity. He was a lot of fun to hang out with at the Las Vegas shows and we often had dinner with him and a few other industry folks, including the late Arthur Loesch, at a local Las Vegas restaurant. Sad that he is no longer with us but this thread has motivated me to seek out some of his work.
