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.

Hello Tonnesen - thank you for your answer and forwarding of Jim Power's e-mail. I will attempt "tightening" of the panels in few days.
I will also test my amplifier - need to borrow something more powerful. I am using VAC Renaissance 70/70 so our problem could be related to not sufficient power supply.
