About the SRM-700S
The STAX SRM-700S is an all-stage FET configuration DC amplification driver unit designed for electrostatic headphones (earspeakers). It uses a custom low-noise dual FET in the first stage and a J-FET in the second stage, with a large current emitter follower output stage for low noise and high-drive capability. The unit is aimed at accurate, highly detailed reproduction and includes switchable RCA/XLR inputs, RCA parallel output, and a bypassable volume control.
