Martin Logan CLS panel distortion

Dear Audiophiles,
My original Martin Logan CLS speakers developed harsh distortion at higher spectrum of frequencies (mostly audible at high pitched soprano voices). Distortion disappears at low volumes of sound. Are my panels getting too old (they could be 10 years old, I am a third owner)? Is there a way to clean/tighten them (the panels, not owners ;-)? Your comments and suggestions will be appreciated. Thank you.

If you e-mail Jim at Martin Logan he will send you back an E-mail describing the use of a hair drier passed quickly over the panels in an attempt to tighten them and remove distortion. It would be worth trying since you would have nothing to lose if you had to replace the panels anyway (about $800).
