The SRM-700S is an electrostatic headphone driver utilizing a fully discrete dual FET. The output of the J-FET and the large current emitter follower circuit are low noise. Accurate music reproduction is realized without missing any fine details.
New semiconductor driver with J-FET in the amplification stage. All semiconductor driver unit that has adopted custom-made low-noise dual FET at the first stage, and for the first time in STAX driver unit history J-FET has been employed at the second stage. The output of J-FET excellent in low-noise amplification as well as large current emitter follower circuit brings out the full performance of earspeakers. Even the music source with much high-frequency ingredients can easily be driven. The driver unit pursues an exact reproduction of musical details.

STAX produce exclusively electrostatic headphones, or “earspeakers” as they call them, in Japan, since 1938. STAX chose the electrostatic technology for its ability to produce transparent sound, and low weight for comfort/ergonomics, both due to the driver design not employing fixed magnets and moving coils, as opposed to other common headphone driver designs. The minimal weight of the driver ensures a very quick response to the signal, creating a more faithful sound reproduction.
n, and powers my headphones in a manner that allows every single instrument to be distinguished from those around it, and allows one to recognize individual singers from each other even when multiple singers are singing background parts. The combined effect from these headphones and this amp is nothing short of amazing.
As in my review of the Stax SR-007A headphones, I would also like to mention the excellent service and honest advice advice I received from Headamp. I called with the intention of stating my decision as to what to order, and asking if the items were in stock. Justin noted that while my chosen amp would “drive” the chosen headphones, a different amp would do a better job, and explained why. I am very glad that I followed his advice. He kept me from making a significant “electrostatic rookie” mistake.
What’s more, every time that I called Headamp, the telephone was answered on the first ring, and each time I have written, I get a response in 12 hours or sooner (and can communicate instantly via chat also). In this world of wading through five-minute menus only to be put on hold for an hour, this is quite refreshing. To me, this shows that the folks at Headamp are very serious about customer service. Thank you Headamp for a thoroughly enjoyable decision and purchase experience, and thank you Stax for making such excellent products. Read LessRead less about I bought this amp with the Stax
