T8000 Energizer

The SRM-T8000 is an exclusive driver unit (power amplifier) with 4-input selector developed in order to ideally drive STAX electrostatic earspeakers

2 Years


The unit incorporates a high-quality double-axis 4-gang volume controller along with XLR connectors that can connect to all kinds of analogue line-level output terminals.

The hybrid amplifier configuration with strictly selected low-noise 6922 dual triode tube for the first stage and high-current emitter-follower at output stage brings out the maximum performance of earspeakers. Its natural un-coloured sound has been realized by eliminating the coupling capacitor that affects sound.

The balanced amplifier configuration with low-noise dual triode tube eliminated transformer or inverting amplifier after the XLR balanced input terminal.

Non-magnetic chassis construction is employed, and only the carefully selected electronic components free from aged deterioration are used taking both their sonic quality and performance into consideration.

The SRM-T8000 is equipped with “direct mode” function, enabling it to connect to preamplifier output terminal or to use your favourite Also, two RCA inputs and XLR balanced input can bypass the incorporated volume controller (Line 4 input does not have this function).

Optional extension slot (LINE4) is provided for future use. Refer to the instruction manual of this optional card.

The foot rubber of the SRM-T8000 features fire-resistant ultra-hard high- grip type and vibration-proof properties. So the unit hardly slides when placed on a table etc. Please lift it up when you move it.

Please note that this device can only drive STAX’s electrostatic earspeakers
