About the SRM-700T
The SRM-700T is a hybrid electrostatic headphone driver unit for STAX earspeakers, combining a precise solid-state FET input stage with a musical vacuum-tube output stage using 6SN7 tubes to deliver warm, spacious high-end performance. Inspired by the flagship SRM-T8000, it uses a custom-made low-noise dual FET in the first stage and a high slew-rate 6SN7 vacuum tube in the second stage for low distortion and excellent transient response. The amplifier provides RCA and XLR analog inputs (typically switchable), plus an RCA parallel output for forwarding the input signal to another component. It is designed exclusively for electrostatic headphones/earspeakers with PRO-bias 5-pin connectors and offers high output voltage and wide bandwidth for demanding electrostatic loads. The chassis uses non-magnetic aluminum construction, often with large vibration-resistant feet/insulators, and is available in at least silver and black finishes, depending on market.
