SRM-727II (MK2) by STAX Audio is a powerful solid-state Class A headphone amplifier for use with their range of electrostatic earspeakers.

For the first time ever in a STAX driver unit, the SRM-727MK2 uses a semiconductor output drive stage and a non-feedback output stage. This makes it possible to achieve a much more vivid and dynamic sound quality, with frequency response raised from 110kHz to 115kHz.

Description

SRM-727MK2

For the first time ever in a STAX driver unit, the SRM-727MK2 uses a semiconductor output drive stage and non-feedback output stage. A pure balanced DC amplifier configuration is used for the large current emitter follower Class A output stage.

This makes it possible to achieve a much more vivid and dynamic sound quality, with frequency response raised to 115kHz (up from 100kHz).

A high level of sound purity is delivered through the simple two-stage amplification circuit with low-noise FET input stage. A significant increase in dynamic range is evident, especially in the upper frequencies.

This is a brand-new headphone driver unit that opens up new vistas for the sense of mass and textural expression, supported by a virtually unparalleled degree of resolution, a natural sense of openness, and a solid, expressive power section.

SRM-727MK2 also features a newly-designed front panel, with rounded corners in brushed aluminium finish, and a Bypass Mode that enables direct connection to preamplifiers, passive volume controls or integrated amplifiers and receivers with pre-out. This is a direct switch that avoids duplication of volume controls.

Brand

STAX

Founded in 1938, STAX brought the world's first electrostatic headphone to market in 1960 and today continues their long tradition by offering the finest 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 for their products.
