Your favorite Electrostatic, Panel spkr

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.

We have been selling new and used audio equipment for 40 plus years, We get to see and hear a lot of different speakers. We would not go so far as to suggest what speaker is better for you over other speakers that are on the market, system synergy, room interaction and most of all personal taste are critical when evaluating equipment. What we can tell you is that a large percentage of our customers who listen to jazz and or classical own planers or ESL in one for or another.
 One of the rooms that we do our initial listening and testing in is almost exactly the same size as yours and through experience we can tell you that if you put to large of a speaker in a room that size you will quickly overload the room. Right now we are burning in a new 2 channel amp ( 400 watts x2 @8 ohm) for a customer and it is hooked up to a pair of medium size planer speakers with 2 small subwoofers, some of our customers are impressed by the sound others do not like it at all, only you can decide for yourself which camp you are in.
