STAX SRM-T8000
SRM-T8000 is Stax's latest flagship electrostatic headphone amplifier utilizing hybrid technology. It employs two 6922 in the input stage, driving a Class-A solid-state output stage. The vacuum tubes isolated in a separate section made of vibration-proof damper and shield cover to eliminate vibration and noise. The high-capacity large toroidal transformers and selected high-quality parts allow the highest refinement in sound.
FIRST LARGE-SIZED TOROIDAL TRANSFORMER, CLEAR HIGH-QUALITY SOUND
The SRM-T8000 is the first driver unit by STAX that has a large-sized Toroidal Transformer. This reduces the leakage flux and helps in keeping noise low. It also leads to high-speed reproduction of sound across a wide frequency range. The SRM-T8000 uses a 6922 dual triode tube. These high-quality tubes are mounted on an independent board to eliminate vibration and noise.
STAY CONNECTED, HIGH-GRADE MATERIALS & LIGHTWEIGHT AND BEAUTIFUL
Now you can easily connect your earspeakers with this driver with 4 pairs of input (the fourth one is optional). These can bypass the volume controller letting you use the SRM-T8000 as an exclusive power amplifier. What does combining an aluminium insulator, vibration-proof material and high frictional coefficient lead to? Well, a really high amount of friction power. This, and other high-quality electronic parts, together give you great tone quality and performance. Unlike most driver units that have an iron chassis, the SRM-T8000 has a non-magnetic aluminium chassis. This has made the unit lighter while eliminating a cloudy tone quality. The aluminium also adds to its sleek look.

SR-x9000
The history of X, the gene of Ω
The ideal electrostatic earspeakers. The fixed electrode which reduces air resistance and the effect of reflection. This electrode also has the high sound transparency. This vision was already found in the metal-mesh electrode of SR-X, which was released in 1970. After that, STAX challenged to realize metal-mesh electrodes for SR-Ω in 90’s again. However, the big metal-mesh electrode was difficult to manufacture. So, the mass production was extremely difficult. This is why SR-Ω was produced in small quantities even though this product has high quality sound.
Evolution to “MLER-3”
20 years have passed since SR-Ω was released. In the meantime, the manufacturing technology of metal-mesh was improved. And through the development of SR-009, the know-how of manufacturing multi-layer fixed electrodes evolved. These factors realized the new flagship “SR-X9000”. “MLER-2”, which was installed in SR-009S, evolved into the four-layer “MLER-3”. An etching electrode and a metal-mesh electrode are bonded using the diffused junction (thermocompression bonding). After 2 generations of STAX flagship models, STAX’s manufacturing technology makes a significant contribution to the stable mass production of big round shaped metal-mesh electrodes. For MLER-3, sound transparency evolved more smoothly than conventional multi-layer fixed electrodes. And the rigidity characteristic resistant to vibration also evolved.
Passion for metal-mesh
The round shaped metal-mesh which was installed in SR-X reduced air resistance and the effect of reflection. This increased the sound transparency. So, metal-mesh is the ideal material of fixed electrodes. However, bigger and thinner metal mesh electrodes are poor in rigidity and may make sound unclear. This is the reason why it was too hard to install metal mesh electrodes in STAX products. In 1990s, SR-Ω, in which the metal mesh electrode is installed, was developed. Because the metal mesh electrode was made bigger for this model, it had to be reinforced with an adhesive by hand. This is a very high precision work. So, it was extremely difficult to manufacture metal mesh electrodes for SR-Ω. The stable mass production could not be realized. This is the reason why SR-Ω was sold in very small quantities in spite of its high sound quality.
The diaphragm increases 20% in size compared with the previous flagship model
The diaphragm is made of ultra-thin super engineering plastic film. Due to weight saving close to zero, great transient characteristic is realized. From the base to the high range, the linearity of the sound is improved. The area of the diaphragm increases by 20% compared with SR-009S. This breakthrough realizes the widest sound field ever.
The enclosure which is made of tough machined aluminum eliminates unnecessary vibrations
The enclosure of the sound unit is made of tough machined aluminum. This new design firmly fixes the sound unit and completely eliminates unnecessary vibrations. The sound wave from the unit flows more smoothly. The acoustic characteristic inside the enclosure is improved to realize clearer sound unaffected by sound reflection.
The tilt guard mesh design
The guard mesh which is installed parallel to the sound unit generates the direct reflections which affect a bad influence on the sound. This problem is solved for SR-X9000. The guard mesh has pillars of different heights in front and back. This design changes the height of the gap between the sound unit and the guard mesh. So, the guard mesh cannot be parallel to the sound unit and the reflection angle is completely controlled. The clear sound which is not affected by reflection is realized.
The stainless-steel arc assembly with 9 steps adjusting click system
The arc assembly is made of stainless steel. The arc assembly is more tolerant to torsion and the earspeakers more stably fit your ears. The “I”-shaped stabilizer on the top of the arc assembly eliminates unnecessary vibrations and decreases the return of unnecessary vibrations to the unit. The material of the head pad which directly contacts to the skin is genuine leather. The position can be adjusted by the slider parts with 9 steps click system.
The comfortably fitting ear pads
The material of the ear pads is genuine leather (sheep skin) which has excellent breathability and softness. Genuine leather makes the earspeakers to closely fit your ears for a long time and you can fully enjoy the high-quality bass and vivid sound. This also reduces fatigue and you can comfortably listen to the music for a long time.
STAX original low-capacity wide hybrid cable made of 6NCu ultra-pure annealed copper wire and silver-plated annealed copper wire
The material of the core cable is 6NCu ultra-pure annealed copper wire (φ0.14×3). The material of the around core cable is silver plated annealed co
pper wire (φ0.08×9). STAX original wide parallel 6-strand cable is used.
Replaceable cables
The cable can be replaced. You can change to a higher-class cable in the future and easily maintain the cable when the cable is broken. 2 cables (2.5m and 1.5m) are attached and you can choose according to your listening style. The inlets of the cables are installed tilted to the front (not vertically) based on ergonomics. This design contributes to more suitable fitting to your head.
The storage case made of “paulownia wood”
The storage case is made of “paulownia wood” which has low thermal conductivity and humidity control capacity. This case is the best storage solution.
