Frank - I see that I have missed quite a few posts on here today! This is a very busy season for me, as you can imagine. Anyway, Albert and Aplhifi have certainly gone much farther than I ever could towards answering the question you last put to me - all I can say is "yeah, what they said!" :) Seriously, though, one of the reasons I love this site is that I can read such posts by Albert or Atmasphere, who are both excellent at describing the technical reasons in layman's terms for things that I know I can hear, but don't have the technical knowledge to explain to someone else why I am hearing it. I realize that's a terrible sentence I just wrote, but it's late, and there is a reason I am a musician, not a writer, LOL!
