EXPERIENCE HI-RES AUDIO WITH THE ALL-NEW STAX - SRM-D50
The STAX SRM-D50 is a desktop amplifier/DAC for STAX electrostatic headphones. It has an ESS ES9018 DAC chip.

The R-core power transformer offers less leakage flux.





DURABLE & COMPACT WITH EASY OPERABILITY
The SRM-D50 has been designed to be super-durable. The non-magnetic aluminium chassis is 4mm thick making it more robust. At the same time, it is also compact to easily fit on a table.
