STAX/SRM-400S Semiconductor type driver unit

STAX / SRM-400S Semiconductor type driver unit

The new semiconductor driver unit STAX / SRM-400S is the successor model to the SRM-353X. A custom low-noise DUAL FET is installed in the first stage, and a FET is also installed 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 high-end model SRM-700S.
