Exquisitely Engineered SRM-400S New DC Amplifier With FET Installed In All Stages

STAX introduces a new semiconductor driver unit SRM-400S, the successor model of SRM-353X. The solid-state amplifier, SRM-400S, exhibits remarkable versatility and excellence. Your appreciation will grow as you progress with your listening session. STAX introduces a new semiconductor driver unit SRM-400S embedded with STAX custom-made low noise DUAL FET installed on First Stage with a FET also installed on Last Stage. The characteristics of right FET and left FET are measured strictly. SRM-400S is an amplifier with FET installed in all stages. In addition to the conventional power transformer for the high voltage circuit, the newly designed power transformer with the winding for the low voltage circuit is installed in SRM-400S. The low voltage winding improves the power efficiency and achieves further power saving and better sound quality than the conventional driver units. The complete DC amplifier configuration of the signal circuit includes no coupling condensers.

Experience Hi-Fidelity And Distortion Free Audio With The STAX SRM-400S

SRM-400S amplifies the analog signal from the input with as little fuss and distortion as possible. SRM-400S is a promising new model with a renewed driver unit lineup with each range well harmonised from the low to high. SRM-400S does justice across the frequency spectrum with greater precision. It is a rock-solid performer that deserves the attention of anyone who’s looking for an electrostatic headphone amplifier capable of driving high-end earspeakers. Its sound is undistorted, sparkly, and exciting. SRM-400S has an impressively wide soundstage delivering full-range sound.

Visual Glory With A Solid Built Chassis, Dual-Volume Knob Along With RCA & XLR Outputs

Experience full visual glory with the all-new chassis that is more rigid than the conventional models. The chassis has a hybrid structure using a lot of non-magnetic aluminium and further reduces the effect of the environmental noise factors such as vibrations. SRM-400S is embedded with a custom-made concentric dual volume knob and RCA parallel out functions. As for the aesthetics, you will find the understated elegance and simplicity of SRM-400S extremely attractive. The front and the back conform to the familiar STAX design architecture.
