Does my Pass amp dislike my Meridian preamp?

Atmasphere - I don't know whether the drivers are ok. I can only say that the distortion I am hearing is coming out of all the drivers. It was on the basis of that that I concluded that the crossover was damaged. But the drivers may very well be damaged as well.

The amp driving the speaker seems ok, as I have run it to a different speaker and do not hear the distortion. I also tried the problematic speaker with a different amp, and the distortion was present. So it seems like it's the speaker that has the problem.

My larger concern is that whatever has been causing the G68 to freeze up and to make "popping" noises through the speakers is also damaging the speakers. The center channel was the first to show it, but I'm afraid that the FR and FL are next.

Atmasphere,
I agree 'almost completely', which is to say--like lightning damage, virtually anything can happen--but, as usual, you're a fountain of really, really good information.
As to the original question...it's obvious from here in Louisville, some several hundred miles from the problem, lol, that the Meridian is the problem.
'Problems' between amps and preamps are like marital problems, they're usually solved by a third party, which is to say a therapist (or nosey neighbor or friend at a bar) or a lover, (a technician who can 'fix the problem' with a few tweaks--define tweaks however you will in this context,lol)

After hearing about my damaged center channel, my Meridian dealer has returned to his theory that the cause of the problem is some kind of "leakage" out of the Pass Labs amp.

I have a multimeter. Are there measurements I can take at the amp's inputs to see if there is some kind of "leakage"?

The only thing I can think of is dc offset...but I believe that the Meridian has an ongoing problem--an easy eval from Louisville, KY. (Don't laugh, Ashly Judd has a clause in her contracts that Kentucky has to be mentioned in her movies, and SHE'S cute! Are you?
Anyway, it's almost assuredly the Preamp/Processor that has the problem and unlikely that the Pass amp is backfeeding the preamp something harmful...

I guess one way to deal with it would be to have the PASS tested by a qualified tech to determine if it is displaying any aberrations. I have one of the best techs in Canada about 10 miles away from me and he has tinkered with various bits of my gear in recent years. When I told him I had bought a c5 year old X-250, his reponse was : "I dont imagine I'll be peeking under the hood of that piece for another 15 years or so'.
