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. A STAX First 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.
