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.

Tonnesen, definitely try another amp before giving up on the panels. I've been driving my IIZs hard for 11 years, 9 of those with an Aragon 4004 and have had no panel distortion issues, just a flattening/hardening of the sound when I push the amp too hard. Just this week I've been auditioning amps to upgrade the Aragon and discovered that the 150W VTL couldn't even begin to drive the CLSs-- major distortion in the upper mids at moderate listening levels. Too bad since the VTL otherwise sounded pretty wonderful.
