Making good even better
It is an old Japanese tradition to always strive for absolute perfection. Perfection, as impressively expressed, for example, in the Japanese tea ceremony. The STAX SRM-T8000 is the counterpart to this when it comes to headphone driver amplifiers for electrostatics.
Not only does it draw on decades of experience and the unconditional will to perfection of the STAX developers, but it also offers an incredible range of functions: For example, two STAX headphones can be operated simultaneously with the STAX SRM-T8000. Like all STAX driver amplifiers for electrostatic headphones, the STAX SRM-T8000 is connected to the tape/record out of preamplifiers and integrated amplifiers or to the pre out of a preamplifier. The source device to be played is then selected using the input selection of the preamplifier or integrated amplifier - however, a CD player or a turntable with a separate phono preamplifier can also serve directly as a signal source. In total, up to three source devices can be connected directly, one of them even symmetrically via XLR. The selection of the source device to be listened to is then made on the SRM-T8000 itself. The music signal present at the input of the driver amplifier can be looped through to connect another device. If a source device is to be connected digitally, a separate D/A converter is necessary.
Technology for excellent sound
- Tube input stage with two E88CC (6922) double triodes, mounted on a sub-chassis for mechanical decoupling.
- Class A output stage without negative feedback
- Signal-balanced circuit design.
- Volume/balance control via an electrically shielded, encapsulated quadruple potentiometer with mute and bypass.
- Four front-selectable inputs: 1x balanced (3-pin XLR jacks), 2x unbalanced (RCA/Cinch jacks) and 1x optional input module.
- One unbalanced output (RCA/Cinch jacks).
- Two headphone outputs.
Note on the operating voltage (polarization voltage) of STAX headphones
Many early STAX headphones are designed for an operating voltage of 230V/DC. PRO series headphones - which include all current models - require a higher operating voltage of 580V/DC.
In the past, driver amplifiers were offered that also provided both operating voltages. Current devices only have connections for the higher operating voltage of 580V/DC.
To avoid confusion, the connection sockets for the different operating voltages have different pin assignments.
