Description

Stax introduce the world’s first portable DAC and electrostatic amplifier
Precision machined from solid billets of aluminium, the two-piece case of the SRM-D10 goes through multiple processes to ensure a smooth luxury velvet feel. Fit and finish, like all Stax products is superb and with its striking industrial design, SRM-D10 is a piece you won’t want to hide away. At 141mm wide, 75mm deep and 32mm high, the SRM-D10 is also truly compact
Stax also has a world first
The SRM-D10 uses an Astronautic level high voltage amplifier to provide the drive and high voltage necessary for the electrostatic diaphragm. This high voltage amplifier is based around a chip from a company called Apex. Apex manufacturer the highest quality parts for the aerospace and medical industries. The Apex chip used in the SRM-D10 is the same as that used in the Apache helicopter. This chip together with the new output stage developed for the SRM-D10 is the most advance Stax has ever made for any energiser.
High-resolution playback
On the digital side, the SRM-D10 uses XMOS USB interface support for DSD 5.6MHz signal playback and PCM audio with up to 384KHz sample rate.
State-of- the-heart
On the digital conversion side, Stax chose to use the ESS ES9018 DAC. Renowned for its superb sound quality, the ES9018 is then fed to a TI OPA1642 ultra-low distortion op-amp to ensure the delicate bitstream remains unaltered.


Selected components
Audiophile grade components complete the output stage, ensuring the SRM-D10 drives any Stax Earspeaker to its full potential. On the rear of the SRM-D10, a switch is provided to select either a digital input or the analogue input.
Separate power supply
A separate power supply provides the necessary voltage for re-charging the Lithium-Ion battery in the SRM-D10. During use, the SRM-D10 will give 5 hours use on the analogue input and 4 hours on the digital input.
