STAX is excited to present their newest solid state amp, the STAX SRM-400S Electrostatic Headphone Amplifier, as the successor to the SRM-353X. The 400S features custom-made low noise dual FETs installed on the first stage and additional FETs in the last stage. SRM-400S follows the design and the manufacturing method of the high end model SRM-700S, in which high quality FETs are installed in all stages of the amplifier.
HeadAmp is accepting pre-orders for the SRM-400S, which is expected to begin shipping in mid/late May 2021.
