Using Martin Logan speakers with tube amps??Any experiences??

In. General, how many years lasts an electrostatic panel before it losses their optimal performance??

Depends how humid, if your a smoker, if it’s in a dusty environment, how often your prepared to vacuum them to get dust off them, and I forgot little mini flying bugs (moths) are bad news also (I vacuum them every 2nd time the house gets done)
I got around 20years out of a set of ESL panels before they start to decrease in the HT (ML’s 5kv) on the Mylar diaphragm. (I always turn them off when not listening, they take around 1/2hr to come up to full charge, which is fine as so does the rest of the systems electronics)

But their worth it, the only thing that comes in second was big Apogee’s and Magies with full length ribbons, everything else is also rans in my opinion. The only thing to better them all in the upper mids/highs is a Plasma tweeter, which I use from 10khz up on my ML’s

It’s all about the mass of the diaphragm that has to be moved and respond without delay back an forth without any over/under excursions, especially in the upper mids and highs where it has to move back and forth much faster.

Asking a bit much of the AR which only gives max 50w from the 4ohm tap at already 1% distortion, to do both the ML’s ESL panel and bass as well!!
My guess it would have been a different outcome, to horizontal Bi-Amp’d the Aries with a cheap 100w Class-D on the bass section.

I have a pair of cary cad 805ae monoblock amps, which are pure class A, 50 watts per channel.What do you think?.

I had the same as the Cary 805’s I built, but my 40kg mono’s used an interstage transformer between the 300b driver and the 805 tube, they were even a bit more powerful than the Cary mono’s.
As for driving the ML’s, yes they did drive just the esl panel (SS on the bass) of my ML Monolith’s to a "certain level" nicely with non complex, non wildly swinging dynamic music.
But even with excellent output transformers and lowish output impedance they still were recessed in the highs where all ML’s have their lowest .9ohm impedance. Good stable high current, high biased Class-A/B solid state will do better.
