Introduction
The limited edition driver
unit was launched to enjoy STAX ear speakers in the finest way
possible.
The exceptional performance of the SRM-600 Limited opens up
a new dimension of music
reproduction, where nothing else comes even close! The output
stage of the SRM-600 Limited has
adopted a high-power dual triode “ECC99” from Slovakia
JJ Electronic. This triode is renowned for its high-grade vacuum
tube technology and manufacturing. The detail and dynamics that
the addition of this triode brings, further enhances the
quality and performance of the SRM-600 Limited, which is more
than a little special.
The newest hybrid type driver unit with FET input and dual triode
output, adopting a pure
Class-A balanced amplification circuit
Output stage employing “ECC99” high-power dual triode.
The vacuum tube from JJ Electronic (one of the best and most-advanced
devices available today)
is manufactured with the assembly accuracy of ±0.02mm
or less and up to 5,000 hours
of lifetime test. Essentially, the “ECC99” is a
high-power dual triode developed for the
driver stage of a power amplifi er as well as for the output
stage of a preamplifi er. In this
new driver unit the tube is used for the output stage featuring
a pure class-A, balanced amplifi cation circuit. Taking advantage
of a dual triode enclosing two triodes inside, the HOT and COLD
signals can be amplified and output through each triode. With
its high linearity and ample power bandwidth, the SRM-600 Limited
faithfully reproduces music
signals that quickly change dynamically. Input stage with pair-matched
low noise FET
Low-noise, high-impedance discrete FET’s have been employed
for the input stage.
These devices are strictly selected by STAX so that the HOT
and COLD parts of the balanced signals
are amplifi ed in mirror image. They are used in a pair-matched
hybrid confi guration, which also heat balance into consideration.
This enables the XLR balanced input to perform a purely balanced
transmission and amplifi cation straight from input to output.
Moreover, the RCA input also keeps its sound purity in such
way a way that the GND side is simply connected to the COLD
side without using an inverting amplifi er, and a high-quality
audiograde relay serves as the three-line input selector.
Power
supply with large-sized power transformer and low ripple circuit
The
power supply section supporting the pure balanced transmission/amplification
circuit
has adopted a large-sized power transformer with the biggest
capacity among STAX
driver units. This ensures an adequately wide dynamic range
as well as the stable operation
even when mains voltage fluctuates. Simultaneously, low-noise,
low-loss short key
barrier diodes as well as capacitors with large capacitance
are incorporated in the
rectifi cation circuit to drastically eliminate ripples distorting
sound. Moreover, the heater power supply circuit
for the “ECC99” high-power dual triode features
a righ-and-left channel independent construction, which greatly
improves both
the S/N ratio and the channel separation
Strictly
selected components such as high soundquality 4-gang volume
controller
The
high sound quality 4-gang volume controller with double-axis
structure ideally
adjusts the input level of HOT and COLD signal on both right
and left channels. Furthermore,
non-magnetic audio-grade carbon film resistors are used for
the load resistance.
3
pairs of input terminals - one for XLR and two for RCA
One
stereo XLR input is for connecting directly to the XLR balanced
output of a high-class CD/
SACD player. Also, two pairs of RCA inputs enable the unit to
switch between connected source
equipment. Additionally, one of the two RCA inputs has a bypassing
output option that for
example, allows you to connect to an integrated amplifier offering
even more fl exibility.
Finish
Graced with a very sophisticated black aluminium front panel
(with hairline finish),
the SRM-600 Limited looks every bit as wonderful as it sounds!
One of the best just got better
The limited six hundred-piece (worldwide) release of the Stax
SRM-600 Limited
means only a lucky few will own and enjoy what will quickly
become a collectors item for many a generation to come.
