In 1959 STAX developed the world’s first electrostatic headphone. Today STAX continues their tradition by offering the finest headphones for both professional and audiophile applications. STAX prefers to all its headphones “EARSPEAKERS”; such Ultra-High Fidelity devices for reproducing music can only be compared with the best cost-no-object loudspeakers, not other headphones. The term ”EARSPEAKER” is therefore more descriptive of STAX’s contribution to today’s most advanced level of sonic transduction.
The Stax SRM-727 II Energiser is Stax's flagship solid-state amplifier for use with its range of electrostatic Earspeakers. It is a direct-coupled FET class A design. It can be used to power one or two sets of Earspeakers.
Only available with silver faceplate.
The SRM-727 II is also available as part of the SR-727 II Omega Reference System.
Please note: like all Stax Energisers, the SRM-727 II must be used with a Stax Earspeaker.Due to the DIN design output it cannot be used with standard headphones.
