The STAX SR-007 Omega II Mk2 Open-Back Headphones and SRM-007T II Amp Combo provides deep powerful sound, significantly improved dynamics and transparency!
NEW & Improved for 2008!
The STAX SR-007 Omega II Mk2 Open-Back Headphones now feature Sheep-Skin Earpads and a Real-Leather Headband for added comfort! The Earpads have a new contoured shape for better sound. The SR-007 Omega II Mk2 Open-Back Headphones also feature improved wiring for a better, more solid connection!
Powerful Sound with Utmost Delicacy
The rationale in the development of the new Omega SR-007 Mk2 Headphone 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 Omega SR-007 Mk2 Headphones the sound
element is 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 Omega SR-007 Mk2 Headphones are provided with earpads that are fully adjustable to the shape of your head.
Deluxe Carrying Case
The Omega SR-007 Mk2 Headphones include a deluxe ATA Style Padded Flight Case
with Gold STAX faceplate. This rigid case provides the ultimate in protection
what the environment!

Parallel Dual Triode Vacuum Tube
The SRM-007T II uses the widely respected STAX original output stage using high
voltage 6FQ7/6CG7 output tubes in parallel. The low impedance of this output
stage is most effective for driving STAX Earspeakers.
Non Inductive Wirewould Load Resistor
Because of the detrimental effect on sound quality by the load resistor STAX
have adopted a non-inductive Dale wirewound resistor. Favored by audiophiles the
Dale resistor along with the parallel 6FQ7/6CG7 provides significantly improved
dynamics and transparency.
Balanced Circuit with First Stage Low Noise Dual FET
The SRM-007T II features pure balanced circuit with no transformer or inverting
amplifier in the signal path. A high quality 4 - Gang Volume control is used for
the XLR balanced input to minimize sonic degradation.
Hybrid DC Amplifier Configuration
By eliminating undesirable coupling capacitors throughout the circuit through
the use of a hybrid DC configuration with transistor and valve, STAX have
achieved pure uncolored sound.
New and Improved for 2006!
The operational principle of the electrostatic condenser type is based on a
system whereby plus and minus output signals are input by push-pull into two
electrodes sandwiching a diaphragm with a high level of accuracy and
equidistantly, resulting in the vibration of an ultra-thin membrane through the
repulsive force and suction force of static electricity, which is then converted
into sound. The balance method, which is considered to be the ideal for
amplification, is thus extended to speakers. The electrostatic system entails
input by balance, output by balance, and sound conversion by balance, and, in
realizing all these features, constitutes the perfect balance system. It is the
only system that makes it possible to listen to sound in the ideal manner
permitted by the balance system.
The new SRM-007tII is our flagship model of a driver unit intended exclusively
for earspeakers characterized by their wide range, high dynamic range and
outstanding operating features with full allowance made for SACD and other
new-generation high-density formats. The ultra-light polymer film, only a few
microns thick, realizes unprecedented response and a high degree of resolution.
Since it is driven on all sides, there is almost no partitioned vibration and
there is no phrase distortion. Nor is there any imbalance in the sound quality
of the unit or distortion caused b7y the network. Electromagnetic distortion
also does not occur.
It opens up the world of high sound quality that is the mark of headphone
listening, a world characterized by the absence of need for large output, the
high degree of freedom permitted by the use of high sound quality elements for
use with small signals, and the even balance between left and right unaffected
by acoustic conditions in the listening room.
Improved circuit, higher grade of reproducibility for SACD and other
new-generation audio formats
Pure balance amplifier in which the XLR balance input does not have to pass
through a transformer, an inversion amplifier, etc.
Simple two-stage amplification structure based on hand selected low-noise FET.
Load resistance consists of non-inductive coil resistance manufactured by Dale,
thus delivering straightforward properties that take advantage of the features
of vacuum tubes and outstanding sound quality with a high level of clarity
Output stage is designed to lower impedance by using a hand selected high
voltage dual triode (6FQ7 type) in parallel connection, which resulted in an
improvement in dynamic range especially in the high frequency
The heater power source for the vacuum tube uses a power circuit of the DC
ignition type using an electrolytic condenser and a high-speed Schottky barrier
diode, further improving the SN ratio
Large capacity power transformer and condenser
Equipped with one XLR (balanced) input and two RCA (unbalanced) input systems,
total of three input systems
RCA inputs, switching with earth side ensures that there is almost no
interference between devices
High sound quality quadruple volume unit which connects with XLR input as well
as any line level analog voice inputs
The RCA terminal "Input 1" is equipped with parallel output terminals and
enables input throughout. Connection with other pre-amplifiers and recording
decks, etc., are possible
