STAX / SRM400S

The new solid-state driver unit STAX/SRM-400S is the successor to the SRM-353X. It is equipped with a custom low-noise DUAL FET in the first stage and an FET in the final stage (amplification stage). It inherits the design and manufacturing know-how of the voltage amplification stage all-FET amplifier adopted in the higher-end model SRM-700S.
