In answer to the original question: Sanders and Janszen are two firms making electrostatic speakers, neither is a big name, and each makes excellent products.
What are some smaller names that compete with the big names in Audio?
I have speakers that are the Gato FM6 that I truly enjoy. I started with High fidelity ct1 products 6 years ago and at the time it was not a big name. What products have others tried that they are happy with. Both have been a blessing. I also didn't want my system to be duplicated by 39 different people. I really enjoy products made by companies doing their best to win you over with performance and not just a name. What do others think?
