    The STAX SRM-007 TII is an electrostatic balanced amplifier with balanced inputs, balanced, outputs, and balanced sound conversion.  It achieves a higher grade of reproducibility for SACD and other new-generation audio format while making use of a simple two-stage amplification structure based on rigorously selected low-noise FET. The output stage is designed to lower impedance by using a rigorously selected high voltage dual triode (6FQ7 type) in parallel connection, which results in an improvement in dynamic range especially in the high frequency. The SRM-007 TII is equipped with one XLR (balance) input system and two RCA (imbalance) input systems. Finally, the heater power source for the vacuum tube makes use of a power circuit of the DC ignition type using an electrolytic condenser and a high-speed Schottky barrier diode, bringing about further improvements in the SN ratio.
