  • The Best Amp/DAC

    The STAX SRM-D50 is a desktop amplifier/DAC for STAX electrostatic headphones. It has an ESS ES9018 DAC chip. This coupled with a TI OPA1642 ultra-low distortion op amp gives you a bit-correct signal representation.


    High-Quality Sound

    The SRM-D50 supports high-resolution audio up to PCM 32/384KHz or DSD 5.6. The R core power transformer offers less leakage flux.


    Durable & Compact

    The SRM-D50 has been designed to be super-durable. The non-magnetic aluminium chassis is 4mm thick so that it is more robust. At the same time, it is also quite compact to easily fit on a table.


    Connect Easily

    The chassis contains one 5-pin output for your STAX Earspeaker and a VU meter. It also consists of various kinds of digital inputs like optical, USB and coaxial so that you can use your favourite source along with the SRM-D50.
