Thanks for the read John. Interesting stuff.
2x6 I'm not sure if you are into the research\reading side of the hobby, but this book may interest you. It is mainly gear quality focused, but delves a little into setup and acoustics. I think it would be a rewarding read for you.
I read it over Christmas break. If you like it there is an uber version called the Complete guide to high end audio.
