Providing the necessary juice for the earspeakers, the Class-A electrostatic amplifier, the SRM-006tS, was engineered to eliminate every possible source of distortion. Relays are close to the input for a short signal path, high-voltage dual vacuum tubes boost the output stage, two-stage amplification with low noise FET expands the input stage, and the mutual interference between the amplifier and earspeakers has been eliminated by alternating signals. For impeccable sound quality and aesthetics straight from the future, give in to your inner audiophile and pick up the Stax SRS-4170.
