I had Accoustats...started on fire.....glad I was home to put it out

I'm going to move a tube amp into my second system room where I have some mature Martin Logan CLSs and see how it goes.  I hadn't really tried it before.

@carlsbad If you have CLS 1s you can do this easily. Any later version of the CLS is much lower impedance, so if you want to use a tube amp with them you'll need a set of ZEROs (www/zeroimpedance.com) otherwise you'll have no highs.

Thank you all for your responses.  I would especially like to thank Atmasphere 

for such a great explanation and Charles1dad for his experience with the VAC

70/70 and Acoustats.  

If I wasn't on a budget I would buy the Atmosphere M-60.

All the best

The Sanders Magtech amp is designed to play electrostatics. Not inexpensive, but should be mentioned to make this thread more complete. A friend uses a 200 watt per channel Classe to drive Martin Logan CLS. I use Acoustat Model 3 ( full range) with Hafler DH 500 modified by Musical Concepts. 

Acoustat speakers seem to be very reliable. Perhaps the most reliable stats made. But, every product breaks once in a while. 

Enjoy the stats,
