Revision 12 January 2018
Discontinued Product

New diaphragm material which raises the resolution of sound.

The thin film of super engineering plastics has been adopted for the diaphragm as a new material. Since an electrostatic type headphone can drive the whole diaphragm surface uniformly, the design concept that gives priority to the exact response to signals over rigidity was possible in its development. After having repeated the trial production and the audition of many diaphragms of different kind and thickness, we adopted the super engineering plastics to obtain high-grade sound suitable for the highest peak model of Λ (lambda) series featuring high-definition tone quality throughout the entire range from rich low-frequencies to delicate high frequencies, and further to secure the high stability against environmental changes of temperature, humidity, etc.

(NEW)The first SR-Λ (Lambda) series was introduced 30 years ago, and now the SR-307 and SR-407 have adopted the same sounding body (sound element) as that of the top model SR-507. The conventional sound element has employed simplest structure so that as wide film diaphragm area as possible can be effectively used in comparison with its external size. Taking advantage of the conventional feature, the new sound element has been packaged in a tough resin case. Thus the new sound element has realized cleaner sound and better reliability. Also a new thin-film material (super engineering plastics) almost free from stretch through temperature or humidity has been adopted, enabling both the rich, deep low frequency and the delicate high-frequency sound.

The SR-003 is a 5-pin PRO bias type in-the-ear earspeaker, and can be used by connecting to a driver unit having 5-pin PRO bias output socket. Also, the inner type structure of the SR-003 enables you to enjoy excellent electrostatic sound readily without covering your ears. The SR-003 connects to STAX driver units or adapters equipped with 5-pin type PRO bias output.
Discontinued Product
The SRS-4170 is a high-quality combination system of the earspeaker SR-407 (Signature) employing the same sound element as the new Λ series SR-507 and the SRM-006tS driver unit with the vacuum tube output stage.

Body color:
SR-407 : Brown

Discontinued Product

The SRS-3170 is a standard combination system of the SR-307 with the sound element featuring the same new material "super engineering plastics" diaphragm as upper models and the SRM-323S solid-state DC amplifier with all-stage direct-coupled balance output circuit configuration.

Body color:
SR-307 : Gray

Discontinued Product

The basic system is a high cost-performance combination of SR-207 and SRM-252S compact-size driver unit still keeping the high-quality sound and high performance of the electrostatic earspeaker.

Body color:
SR-207 : Black
