STAX Lambda SR-L500 MK2 Electrostatic Headphones
- Spacious, open sound
- Open-back, over-ear headphones
- High wearing comfort and light weight
- Frequency response: 7Hz – 41kHz
With the STAX Lambda SR-L500 MK2, technology derived from the STAX Lambda SR-009/009S (for example, the more sophisticated cable technology) enables an even more spacious and refined reproduction compared to the STAX Lambda SR-L300. The materials are also of higher quality, and the wearing comfort is correspondingly better.
All STAX headphones and in-ear monitors are electrostats operating on the push-pull principle. Due to their operating principle, they require a STAX driver amplifier for operation.
Design:
- Black surfaces
- Ear pads covered with synthetic leather
- Comfortable headband adjustment with ten detents.
Technology for good sound:
- Detachable connecting cable made of oxygen-free high-purity copper with titanium admixture (HiFC™), with extremely low capacitance
- Gold-plated connectors
- Recommended driver amplifiers:
- 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 dual triodes
- 2 headphone outputs
- 1 unbalanced & 1 balanced input
- 1 unbalanced output
Tube magic for two – now even better
The SRM-500T is the new entry into the world of STAX triode tubes. The sound is powerful and elastic in the bass, transparent and colorful in the mid- and high-range. The new STAX SRM-500T comes with improved efficiency thanks to a new transformer with separate windings for the high and low voltage circuits and new, specially developed components (DUAL-FET) in the input stage, which further improves the already outstanding sound quality of the SRM-006t. A new, stiffer housing, which now also includes a lot of non-magnetic aluminum, reduces vibrations and eddy currents and now offers the tubes an even better, undisturbed working environment. You can connect your sources via RCA/Cinch or XLR. Thanks to the RCA/Cinch output, you can also loop through the signal and supply 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.
The STAX SRM-500T allows the simultaneous operation of two STAX headphones.
Driver amplifiers for STAX electrostatic headphones can be operated at the recording output (Tape/Record Out or Fixed Out) or at another 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 drive or a streaming bridge) is to be connected, a separate D/A converter is necessary.
Technology for good sound
- Tube output stage with two 6FQ7 (6CG7) dual triodes without negative feedback
- Signal-symmetrical circuit design. Volume/balance control via quadruple potentiometer
- Two switchable inputs on the rear. 1x balanced (3-pin XLR sockets), 1x unbalanced (RCA/Cinch sockets)
- One unbalanced output (RCA/Cinch sockets)
- 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 pinouts.
Our assessment: With powerful presence in the bass range and transparent, colorful reproduction in the mids and highs, this set offers a dynamic entry into the unique sound universe of Stax.
