I guess this is what old men do to still show themselves relevant (no fault of the OP, the topic was legitimate). The proof on this forum is staggering. Topics that have been covered and documented in the 70's make their way back into discussion as if it is something new.
I don't know about other readers here, but I recall learning about the color of frequencies two fold back in my photography and music theory classes. I question if some of these guys ever went to school, or even now with so many of them being Wiki-fied grads how they can turn these threads into two sided spin cycles for the sake of the spin only. I highly doubt anyone from outside these pages are interested in the intellect of the Agon aged. It is good entertainment on a lazy afternoon to cure boredom as Glupson would say, but really only a sign that these guys aren't listening to music as their main hobby.
Agon forum lifers, an interesting bunch of folks indeed.
