STAX SRM-D10 Amplifier and SR-L700MK2 Earspeakers System


The first SR-Lambda series was introduced 36 years ago and it has further developed into a new-generation SR-Lambda with its newly designed enclosure – the new SR-L700MK2 advanced-Lambda series Earspeaker.

The SRM-D10 is the world’s first compact electrostatic amp/DAC. Now, you can enjoy the freedom of using all modern Stax electrostatic headphones (PRO bias) anywhere you go. The built-in high-resolution DAC is capable playing up to DSD128 files.
