STAX SRM-700T Vacuum Tube Type High-End Electrostatic Driver

Description

SRM-700T

Released October 2020, the newly designed SRM-700T is a hybrid electrostatic headphone driver from STAX Audio. Inspired by their flagship model SRM-T8000, the 700T uses solid-state FET as a driver stage and vacuum tube as the output stage.

The first stage is a custom-made low-noise dual FET while the second stage is a clear, high slew-rate vacuum tube 6SN7. The tube output offers warm and spacious music reproduction.

Together, this hybrid design delivers a wonderfully precise, detailed sound with overtones of tube warmth. A great combination.

Perfect for STAX electrostatic earspeakers, allowing the precise detail of your music to shine through.

Update, March 2022: The STAX SRM-700T is now also available in Black finish. We are awaiting images of this new casing.

Brand

STAX

Founded in 1938, STAX brought the world's first electrostatic headphone to market in 1960. Today they continue their long tradition by offering the finest audio products for both professional and audiophile applications.

All STAX headphones are referred to as "earspeakers" - the company states that such ultra-high fidelity devices can only be compared with the best cost-no-object loudspeakers, not other headphones. Their unique amplifiers, earspeakers and drivers are highly sought-after products, and extremely well considered by aficionados in the audio industry.

Unilet Sound & Vision are one of the oldest STAX dealers in the UK, and one of the very few official outlets stocking their products. Do get in touch with us if you would like to audition the range, or need advice or assistance with choosing the right system for your needs.
