Actually that was a disclaimer so that you wouldn't jump on me for propogating an audio myth. I just never know which side you're gonna be on apparently.
Also not that well documented, or at least disseminated - there was a huge debate about that on another, rather large board, and nobody could produce any lit or science on the subject from either side, but thanks for the lead, I will see if I can rustle anything up on that. I was actually planning a test of my own to decide for myself as I have 2 drivers that are identical save for the mag material, though it's ceramic and neodymium vs alnico (I figure it'll prove the point anyway, also I have heard people claim that they find neo drivers 'harsh,' which I never have, but this should show by direct comparison). I have been mostly undecided (leaning to a skeptical no) on the subject due to my lack of reliable evidence either way.
