      Thanks for the advice, if I get the chance I will try an active crossover. I think I may be done for a while though; I am very satisfied with these transducers and I think I will just spend time listening to beautiful music.

      Thank you for the clarification. Nice system. If you ever get a chance, experiment using an active crossover. It would make the Soundlabs even more transparent and dynamic if they do not have to handle any of the primary, second or third harmonics of the lower frequencies.

      1. What cross-over do you use to cross the M1’s and JL Audio Sub?
      2. Aren’t your M1’s too close to the walls? I have been told that I need 3′ away from the sidewalls, maybe not???

        Hi ernestov,

        No cross over so to speak,the Conrad Johnson preamp has two outputs, main1 goes to the power amp, main2 goes to the JL Audio sub. The full audio signal is low passed (in the sub) at 80 Hz. I suppose they may be too close, but I set them up this way initially and have not heard anything deleterious (first, early reflection from the wall).I did move them in about 2 or 3 feet from the sidewall but I did not hear any improvement in how they sound. I run the sub with the M1’s,not at a high level. The sub fills in the lowest reaches, 20-40 Hz and supplements 40-80 Hz.

      Do you run your JL Audio Sub with your M1’s?

      Fell in love with electrostatics the first time I heard a pair 20 years ago. I have upgraded most every component (latest system-5 channel, analog) in the last year. Retired a Spectron D class amp for the Premiere 350. Huge improvement in instrument resolution, clarity and resolution, bass much tighter. Retired a Conrad Johnson ET5 preamp (5 channel analog, tube) and got the ET7-SA. Again, a huge improvement in clarity, precision especially in cymbals, triangles, brass…etc. Pulled the trigger and got a well cared-for pair of M1-PX and changed out Anthony Gallo Reference 3.5 speakers.

      Heaven. These transducers are amazing. It’s been a 40 year adventure and I am finally hearing true high fidelity. I have never heard reproduced audio sound like a live performance; a voice or horn or piano sound like it is being generated by a person in the room or a person playing the instrument in the room. What a joy, Thanks Dr. West!!

      I purchased these units from an interesting man; he has created a methodology he calls- Ambiophonics. A rather brilliant man who has researched psychoachoustics, hearing anatomy and physiology, recording methodologies, the equilateral triangle placement of speakers and listener and developed a method to vastly improve the performance of current audio reproduction systems. I am just starting to investigate this man’s work and I have heard a system utilizing his methodologies and it is shocking. There is a website, ambiophonics.org

      At any rate wanted to say hello and introduce myself as another member who has made his amplifier very happy by affording it the right to finally be hooked up to a fine electrostatic!
