STAX Authorized Web Dealer!
SPECIAL NOTE: Specifications: 120V, U.S. Version, 1 Year Year Parts & Labor Warranty. NOTE: All units available on Japanese websites are the 100volt for Japan only models. They have no warranty in the USA, are a potential fire hazard and will have significantly shortened lives due to the 20% over voltage by USA 120V power!!!
The new STAX SR-007 II and SRM-727II Combo provide deep powerful sound with a
constantly stable output voltage, ensuring compatibility with all new audio
formats including DVD Audio and SACD!
Powerful Sound with Utmost Delicacy
The rationale is the development of the new SR-007 II Earspeaker was to provide
deep powerful sound previously unobtainable in Earspeakers. STAX engineers
developed a unique new electrode structure. Visible through the outer case, gold
plated on the outer edge this new electrode has less holes than conventional
STAX Earspeakers and thus provides an increases diaphragm vibration area
allowing for rich and powerful sound yet retaining all the delicacy STAX is
Rigid Metal Housing
To maintain clear distortion free sound it is most important that nothing other
than the diaphragm should vibrate. Within the STAX SR-007 II the sound element
encased in a thick insulated resin case firmly fixed to the rigid body. The
results are nothing short of spectacular.
Fully Adjustable Earpads
Utmost comfort for maximum enjoyment of your STAX SR-007 II is provided with
earpads that are fully adjustable to the shape of your head.
Deluxe Carrying Case
The 007 Omega II Headphones include a deluxe ATA Style Padded Flight Case
with Gold STAX faceplate. This rigid case provides the ultimate in protection
what the environment!

Class A, Non-Feedback (Non-NFB)
The SRM-727II features non-feedback (NON-NFB) output stage for the first time
ever in STAX drivers. Large current emitter follower Class A amplification circuit.
This makes it possible to achieve a much more vivid and dynamic sound quality
with frequency response raised to 115kHz. (from 100kHz)
A newly designed front panel with rounded corners in brushed finish. Available
in Silver or Black
Pure Balanced System
The electrostatic method is a playback method which involves the installation
of drive electrodes on either side of a high-polymer film diaphragm with a thickness
of only a few microns into each of which a plus signal and a minus signal are
fed. This means that XLR connection with a pure balance output CD player makes
it possible to listen to the original sound permitted by the balance system without
a conversion circuit.
High Quality Parts, High Quality Sound
Careful selection of parts with high consideration on sound quality, performance,
and the environment. Low noise FET is used at the input stage with a simple two-stage
amplifying circuit. A natural and pure sound quality with high information quantity.
SRM-727II provides a bypass mode that enables "direct" connection to preamplifiers, passive volume controls or integrated amplifiers and receivers with Pre-out. A direct switch that avoids duplication of volume control.
