Scratch that question^^^^^.
Apparently, i am the only one that can hear it, b/c my GF and my friend don't hear it, but on certain electric guitar notes...i can hear the tweeters get fuzzy.
It is easier to hear at lower volumes, but i defnitely hear it, but i guess nobody listens as hard to the music as i do....haha audiophile.:-)
I am guessing this happens from too much power, cuz i have them hooked up to my USA 4300x which is about 75wRMS x 4 at 4 ohms....which is what my mids and highs run at.(75wRMS each side, front and back)
I am running DLS Reference PS6's up front, and was planning on saving for some Iridiums, but i might be getting some MS6's instead, or maybe the UP6's.
