BTW... all CLS 1's,later serial # CLS II's and all CLS IIa's "power down" if no signal is received after 20 minutes. So the "air filter" theory goes out the window.
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.
