Description

A full model change of the middle level vacuum tube output driver unit

STAX introduces a new vacuum tube output driver unit “SRM-500T”, the successor model of “SRM-006tS”. STAX custom-made low noise DUAL FET is installed on First Stage and the vacuum tube”6FQ7/6CG7″ is installed on Output Stage. STAX continued to use the traditional circuit design which is perfect for STAX vacuum tube driver and improved the power efficiency. Finally SRM-500T achieved the sound quality improvement.

In addition to the conventional power transformer for the high voltage circuit, the newly designed power transformer with the winding for the low voltage circuit is installed in SRM-500T. The low voltage winding enables to improve the power efficiency and achieve further power saving and better sound quality than the conventional vacuum tube output driver units such as SRM-006tS.

The new chassis which is more rigid than the conventional model is installed. The chassis has a hybrid structure using a lot of non-magnetic aluminum and further reduces the effect of the environmental noise factors such as vibrations. The inputs are RCA and XLR, the mutual exclusion inputs. The custom made concentric dual volume knob which is common to STAX products and RCA PARALLEL OUT functions are installed same as the conventional driver units. All electric components are strictly selected considering the environment. Also the sound quality and the performance is improved. The complete DC amplifier configuration that the signal circuit includes no coupling condensers is one of the biggest traditional features.

The clear and highly transparent sound, a feature of the vacuum tube circuit and the warm and wide sound texture is maintained and the thickness of the low-mid range is brushed up. This is the new choice for the combination with the advanced lambda series (SR-L300/SR-L500 MK2/SR-L700 MK2).

Why Choose Stax

STAX is one of the most respected and historic names in personal audio, renowned worldwide for its electrostatic headphone technology and uncompromising approach to sonic purity. Manufactured in Japan, STAX products are designed for listeners seeking an exceptionally open, detailed, and transparent presentation that conventional headphone designs often struggle to achieve.

For many enthusiasts, hearing a properly matched STAX system for the first time is a genuinely memorable experience. The speed, delicacy, and effortless clarity of electrostatic headphones create a presentation that feels incredibly immediate and lifelike, revealing fine detail and subtle textures with remarkable ease. Vocals, strings, piano, and acoustic recordings in particular benefit from the spaciousness and realism that STAX systems are capable of delivering.

At HeyNow Hi-Fi, STAX appeals to customers who want to move beyond traditional headphone listening and experience something genuinely unique within high-end personal audio. While electrostatic systems require dedicated energisers and careful system matching, the reward is a level of refinement and transparency that continues to make STAX one of the true reference brands in the headphone world.

Signature Design and Sound

STAX products are built around the company’s long-standing electrostatic driver technology, which uses an ultra-light diaphragm suspended between electrically charged plates to achieve extraordinary speed and precision. This design allows STAX headphones to respond to musical signals with exceptional accuracy and minimal distortion.

Sonically, STAX systems are renowned for their openness, air, and micro-detail retrieval. The presentation feels highly spacious and unconstrained, with outstanding separation and a remarkable ability to reveal subtle nuances within recordings. Unlike some conventional dynamic or planar headphones, STAX products often create a sense of effortlessness and transparency that feels closer to listening to high-end loudspeakers in a well-treated room.

Importantly, despite their extraordinary detail retrieval, STAX systems avoid sounding aggressive or overly sharp when correctly partnered, instead delivering a refined and highly natural presentation that encourages deep listening sessions.

Stax Product Range

The STAX range includes electrostatic headphones, dedicated driver units (energisers), and complete headphone systems designed for both enthusiast and reference-level listening. Models including the SR-L700 MKII, SR-007, and flagship SR-X9000 have become highly regarded amongst serious headphone enthusiasts seeking the highest levels of resolution and realism.

STAX driver units and energisers are carefully matched to their headphones, allowing customers to build complete systems tailored to different performance levels and listening preferences. Whether entering the world of electrostatic headphones for the first time or pursuing a true reference personal audio system, STAX remains one of the most iconic and technically unique brands in high-end headphone listening.
