STAX SRM-500T Electrostatic Headphone Amplifier
The STAX SRM-500T is a cutting-edge electrostatic headphone amplifier, succeeding the SRM-006tS after 11 years of meticulous development. Integrating advanced technologies and refined craftsmanship, the SRM-500T delivers exceptional audio performance.
Key Features:
- Advanced Circuit Design: Utilizes a custom-made low-noise DUAL FET for the first stage and high-voltage double triode 6FQ7 / 6CG7 for the output stage, enhancing the traditional STAX vacuum tube driver circuit.
- Improved Power Supply: Features a newly designed power transformer with low-voltage winding, improving efficiency, power saving, and sound quality compared to its predecessors.
- Enhanced Chassis: The new, more rigid chassis with a hybrid structure of non-magnetic aluminum minimizes external noise and vibrations.
- Versatile Inputs: Equipped with both RCA and XLR mutual exclusion inputs, alongside a custom concentric dual volume knob and RCA PARALLEL OUT functions.
- Eco-Friendly Components: All electronic components are carefully selected with environmental considerations, enhancing sound quality and performance.
