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.
The newly designed SRM-700T is a hybrid electrostatic headphone driver. Inspired by the flagship model SRM-T8000, the 700T uses solid-state FET as a driver stage and vacuum tube as the output stage.
