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 power transistor array with effective heat dissipation through large-sized heat sink. Strictly selected pair-matched special FET. High-definition film capacitor made by German WIMA is used. Level control switch that can bypass the volume of the unit. As with SRM-T8000,a shield case is used for the volume device.

Sep 2, 2020 · The SR-009S electrostatic headphones and SRM-700S headphone driver from Stax are a premium duo, but certainly on the pricier side of things.

Aug 4, 2021 · The STAX SRM-700S is a solid state (FET and JFET)—electrostatic headphone amplifier, which means that the SRM-700S can only be utilized with electrostatic headphones. The SRM-700S is clean and very straight forward, as it simply amplifies the signal which it receives from a source—DAC, CD player, phono-pre, etc.

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. Specifications.

In my first STAX article I take a look and listen to the awe inspiring SRM-700S driver paired with the SR-009 electrostatic ear speaker. Thank you to Audrey and Kay for making this possible.

Feb 20, 2025 · SRM-700S: The SRM-700S, being a solid-state amplifier, delivers a cleaner, more accurate sound. It prides itself on its precision and detail retrieval. The soundstage, while still expansive, offers a more accurate positioning of instruments and vocals.

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.

Oct 17, 2019 · After so many years, Stax finally ran out of the long obsoleted Toshiba JFET. The 700t is more like a change that has to be done eventually. But still for some unknown reasons, they still refused to employ CCS in their tube amps.
