Thank you very much for purchasing STAX high-end earspeaker SR-009S.
The SR-009S is the further refined model based on the fixed electrode developed for SR-009 series.
INTRODUTION
FEATURES
Sound element with new fixed electrodes;
If the fixed electrode becomes infinitely thinner, the air resistance will be decreased and the permeability of sound
waves will be improved. On the other hand, thinner electrodes are poor in rigidity and suffer from vibrations of their
own and the sound becomes muddy. The SR-009S evolved further the electrode established in the SR-009 as the
integration of present technology. The edges of electrode hole were smoothened through after-etching processing to
reduce air resistance, and the permeability of sound has been much more improved. Moreover, gold plating pro-
cessing with large specific gravity further decreased the electrode vibration. Finally, the sound clarity has been
achieved by reducing the resistance of electrode itself.
Sound element with new diaphragm material;
The ultra-thin film diaphragm made of super engineering plastics has been employed for the SR-009S to improve
the compliance characteristics of sound over the entire frequency region from low to high.
You can now enjoy the good-sounding tone with good bass response.
Genuine leather ear pad;
The adoption of the Genuine leather (sheep skin) mainly aims at the good breathability of Genuine leather as well as
the improvement of wearing comfort on the head due to its pliability, but it also greatly contributes to the improve-
ment in the "freshness of sound" and "grace of sound." (The wrinkle or gloss condition of Genuine leather, unlike
artificial leather, differs from each other depending on the used part. For this reason, please feel easy even if the
surface of right and left ear pad looks a little differently.)
Wide, low-capacity 6N hybrid cable;
6N Cu high-purity annealed copper wires (φ0.14x3) of high general evaluation are employed for the center cable, and
six silver-plated annealed copper wires (φ0.08x9) are arranged at its perimeter.
The whole structure of the cable features the conventional wide parallel type to reduce the capacitance between
each line. This further improved the "freshness of sound".
New style arc assembly;
The new style arc assembly (head band) features the slider portion equipped with 10-step click mechanism for
height adjustment of the head pad. This enabled the optimal wear comfort for almost all people. Moreover, the ad-
justed optimal position is maintained making it unnecessary to re-adjust it when you use your earspeaker next time.
The new mechanism softens the side pressure to the ear and enables you to enjoy long hours of comfortable listen-
ing to music. Also the adopted dual arc spring system Genuineized both the rigidity and flexibility at the same time.
Enclosure;
Tough solid aluminum chassis employed secures firmly the sound element, contributing to improve the clearness of
sound. Furthermore, the case thickness has been reduced to the limit, making the flow of condensation-and-
rarefaction air wave from the sound element more smooth.
Intensity has been increased by giving roundness to the "guard mesh" of sound element, which lowered the influ-
ence of reflection and improved the resolution of sound.
