STAX SRM-007tII Amplifier
The new SRM-007tII is flagship model of a driver unit intended exclusively for earspeakers characterized by their wide range, high dynamic range and outstanding operating features with full allowance made for SACD and other new-generation high-density formats. The ultra-light polymer film, only a few microns thick, realizes unprecedented response and a high degree of resolution
IMPROVED FREQUENCY RESPONSE
Newly improved circuit raises the frequency response to 100kHz (from 70kHz) to accommodate newer generation audio formats such as SACD and DVD-A.
PURE BALANCE AMPLIFIER
The electrostatic transducer is driven by electrodes set on both sides of the diaphragm which carry the push-pull signals. This is thus virtually the only replay system that enables the listener to enjoy replay unique to balance transmission without the need to pass through a transformer or inversion amplifier.
HEATER POWER SUPPLY
Adopting a rectifier circuits combining low-noise, low-loss Schottky barrier diodes and large electrolytic capacitors. Low-ripple DC power source improves the SN ratio.
A simple two-stage amplifier configuration using high-voltage dual triode tube 6FQ7(6CG7) delivers straightforward properties that are transparent and clear sound quality.
Employs Hand pick low noise FET and 6 acoustic high sound quality relays. Simultaneous switching system adopted from SRM-T2 , input source is isolated of direct current and no interference between different devices.
HIGH QUALITY VOLUME CONTROL
High sound quality quadruple volume unit which makes XLR inputs as well as any analog line level inputs possible
