Above fifthy five years ago (1959), Stax became the first company in
the world to develop and manufacture Electrostatic Headphone,
"Earspeaker". Today, our experience is making a dramatic
difference that you can enjoy. For
example, Daimler-Benz was so taken with "Stax technology" that they
requested a special earspeaker to test
the acoustic environment in their limousines. This earspeaker became well-known
as the SR-Λ Professional. Now, the SR-Λ Signature is the successor to the SR-Λ Professional. It is constructed of select materials and is
hand assembled to meet the superlative standard of Mr. Naotake Hayashi, the
president and founder of Stax.
Stax is proud to have created a new reference standard for earspeakers
that obtains an even higher level of performance than the SR-Λ Professional. The Signature series SR-Λ uses a transducing diaphragm made of high-polymer that is only
"one" micron thick. The signal cord is made of PC-OCC cable that is
specialy cast from pure copper to preserve phase integrity through large linear
crystalline structure.
The SR-Λ Signature is designed to operate at 580 V
D.C. bias.it can be used with any Stax professional adaptor or direct drive
amplifier. The SRD-7/Mk2 and the SRD-7sb/Mk2 are adaptors that enable the SR-Λ Signature and normal-bias earspeakers to work in
conjunction with any high quality amplifier or receiver. The SRD-7/Professional
is an adapter that enables two SR-Λ Signature
earspeaker (or two other pro-bias earspeakers) simultaneously to work in
conjunction with a high quality amplifier or receiver. The SRD-X/Pro and the
SRD-P are portable adaptors. They allow
the use of the SR-Λ Signature in remote locations. The
SRM-1/Mk2 Pro is a Class-A DC direct drive amplifier for any Stax earspeaker.
The SRM-T1 is a Hybrid FET/vacum tube direct drive amplifier that is
Specifically designed to highlight the SR-Λ Signature . It also will drive any Stax earspeakers.
