STAX Lambda SR-L500 MK2 Electrostatic Headphones

Spacious, open sound
Open-back over-ear headphones
High comfort and low weight
Frequency response: 7Hz - 41kHz

In the STAX Lambda SR-L500 MK2, the technology derived from the STAX Lambda SR-009/009S (for example, the more sophisticated cable technology) enables an even more spacious, more refined reproduction compared to the STAX Lambda SR-L300. The materials are also of higher quality and the wearing comfort is better accordingly.

All STAX headphones and in-ear monitors are electrostatic drivers operating on the push-pull principle. Due to their operating principle, they require a STAX driver unit to operate.

Design:

Black finish
Synthetic leather ear pads
Comfortable headband adjustment with ten-step click system.

Technology for great sound:

Detachable connection cable made of high-purity oxygen-free copper with added titanium (HiFC™), with extremely low capacitance
Gold-plated plugs
Recommended driver units:
STAX SRM-D10 (for stationary and mobile applications), STAX SRM-353X, STAX SRM-D50, and STAX SRM-006tS

STAX SRM-500T - Tube magic for two

For electrostatic headphones/in-ear monitors
Tube output stage
2x 6FQ7 double triodes
2 headphone outputs
1 unbalanced & 1 balanced input
1 unbalanced output

Tube magic for two - now made even better
The SRM-500T is the new entry into the world of STAX triode tubes. The sound image is punchy and springy in the bass, with a transparent and colorful midrange and treble. The new STAX SRM-500T comes with improved efficiency thanks to a new transformer with separate windings for high and low voltage circuits and new, specially developed components (DUAL-FET) in the input stage, which further enhances the already outstanding sound quality of the SRM-006t. A new, more rigid chassis, which now also includes a lot of non-magnetic aluminum, reduces vibrations and eddy currents and offers the tubes an even better, undisturbed working environment. You can connect your sources via RCA or XLR. Thanks to the RCA output, you can also loop the signal through and power other devices.

The STAX SRM-500T is the best choice for the STAX Lambda series: STAX SR-L300, STAX SR-L500 MK2, STAX SR-L700 MK2.

Simultaneous operation of two STAX headphones is possible on the STAX SRM-500T.
Driver units for STAX electrostatic headphones can be operated via the recording output (Tape/Record Out or Fixed Out) or any other fixed-level output (Pre Out/Fixed Out) of a preamplifier or integrated amplifier. Of course, a CD player or a turntable with a separate phono preamplifier can also serve directly as a signal source. If a purely digital source device without a D/A converter (e.g., a CD transport or a streaming bridge) is to be connected, a separate D/A converter is required.
