Stax SRM-727II

Driver amplifier for electrostatic headphones from STAX

The SRM-727 II is the transistor-driven sound alternative to the tube-equipped STAX SRM-007t II and plays at the same extremely high quality level. Where the SRM-007t II is very colorful, the SRM-727 II can boast an extremely controlled and tight bass.
The STAX SRM-727 II can be used with two STAX headphones at the same time.

Driver amplifiers for electrostatic headphones from STAX can be operated at the recording output (Tape / Record Out or Fixed Out) or at another output with a fixed level (Pre Out / Fixed Out) of a preamplifier or integrated amplifier. Of course, a CD player or a record player with a separate phono preamplifier can also serve as the signal source. The music signal present at the input of the driver amplifier can be looped through, so you can supply another device with music signals. If a source device is to be connected digitally, a separate D / A converter is required.
