Your favorite Electrostatic, Panel spkr

jperel9, all you have to do is remove any grill cloth, take a heat gun and wave it over the diaphragm at a distance of 6 inches. You will actually see the mylar tighten up! But BIG WARNING do not stop waving and leave the gun pointed at one spot. You will melt the Mylar. Mylar does not get old. It has a half life of 50,000 years. You can heat it over and over again.
The loosening is happening because Audiostatic did not adequately pre stretch the mylar. All ESLs loosen a bit (break in) but usually not enough to cause trouble if the mylar was stretched tight to begin with.

 I currently own Martin Logan Summit X electrostatic hybrids. I love them. The sound is incredibly full and lifelike. I am powering them with concert fidelity 200 W monobloc amplifiers. 

It has been some time since I've owned panel speakers, but, I still like many of them.  I've had Magnapan II, Acoustat 1+1 with a subwoofer, and Martin Logan Quest.  I have heard, and liked, models from Sanders Sound, SoundLabs, Quad, Magnapan, and a number of brands I cannot recall. 

I now own a horn-based system, but, if I were to set up another system, I would certainly consider something like the very old Quad 57 or double stacked Quad 57 (I like them more than the later Quad models).

Love the Quad ESL 57s, but own original Martin Logan CLS - they need care in set up and good stands to get them up off the floor but offer a bigger share of magic than any of their other models I have listened to (haven't heard the CLX bit would like to). Their hybrid systems have never captured my admiration.

I keep four systems and the other three are conventional speakers but the CLS will always have a place in my gear.

I have a pair of XStatic EC/X full range electrostatic speakers paired with Klipsch 112SW subs (the subs are OK, but the weak link here).   These are all powered by my PrimaLuna HP integrated tube amp.  Sources are all high-res digital.    At 34W in triode mode the amps play these louder and more accurately than my wife will tolerate...   Still the best sound I’ve heard in a system under $30k.

Before this I’ve owned MArtin Logan, Acoustat 2+2, and Magnepan, etc.   once you hear a full range, no crossover speaker it’s hard to go back.
