STAX SRM-T8000 HEADPHONE AMPLIFIER
Stax has announced a new hybrid headphone amplifier which uses a 6922 twin-triode in the pre-amplifier section and solid-state Class-A circuitry in the power output stage. The Stax SRM-T8000 has the twin triodes mounted on a separate PCB that’s vibrationally isolated and shielded from the chassis to prevent external vibrations and noise from affecting the performance of the valve through microphonics.
The SRM-T8000 uses a large, high-current toroidal transformer in its power supply and has a bypass function that removes the volume control from the circuit, so you can instead adjust volume using an external device. It also has a pass-through input (input 1 of the two line-level unbalanced RCA inputs) so you can route a signal through to other components. In addition to the two unbalanced inputs, there’s a balanced input, via XLR.
Stax rates the frequency response of the SRM-T8000 as 1Hz to 115kHz, with THD of less than 0.01%. With a sensitivity of 100mV it provides gain of 60dB. It measures 320×103×395mm (WHD) and weighs 7.3kg. For more information, contact Audio Marketing on (02) 9882 3877 or at www.audiomarketing.com.au
