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.

Try to examine tubes in your amplifier. If it's old than upgrade or replacement of passive components should probably take place to bring your amp back to tolal balance.

Golden ears,
they can dip and jump to increadibly high impedance.

The best successfull way to deal with them is to bi-amp using OTL that realy cares less about high impedances and beefy SS on the bottom certainly with active crossover.

All tube stuff is also possible having beefy VTL on the bottom and some 25...30wpc OTL at the top.

I actually heard many of Martin Logans speakers and no setup I realy liked with them and than they have one of the most complexed impedance characteristics on earth.
