High-Resolution
Audio takes your digital music to another level. By converting analogue music
to digital at a higher rate than CDs – 24-bit/192 kHz, as opposed to the 16-bit/44.1 kHz rate of CDs – High-Resolution Audio is able to deliver better
than CD quality sound, so you can get closer to the original studio recording.
FET
input buffer
The amplifier has
been fitted with a FET input buffer and discrete circuit for the pre-amp. This
reduces the effects of distortion while enhancing the sound quality of
High-Resolution Audio.
Optimum
gain volume control
We’ve combined the electronic volume with a
discrete buffer amp – co-developed with Sony – to enhance the overall sound
quality by reducing the gain error experienced by conventional amps.
Simplified
power amp circuitry
By including fewer
transistors and eliminating the emitter resistor and coil & capacitor
needed in the amp’s final stage circuitry, we’ve reduced the distortion that
affects the quality of your music. This means the amp can deliver a higher
power output, so you can push up the volume and enjoy great, undistorted,
High-Resolution Audio.
Make
a secure connection
Poor component
connections can have a significant impact on overall sound quality. The new
screw-type terminals and deluxe quality shaved pin, 18mm pitch jack ensure a
tight, secure fit between the amp and your components, reducing the chances of
sound degradation.
Smart
BIAS
The built-in smart
BIAS system controls the amp’s BIAS based on the volume position. In doing so,
the amp is able to utilise a field that experiences good transistor linearity
without generating heat, so the sound quality always remains true.
Independent
HP-AMP
To reflect the
growing popularity of premium-quality headphones, this amp includes a
specialised discrete amp with gain optimised to match headphone impedance.
Main features of the
amplifier
This power amplifier
achieves dynamic output by using a single push-pull amplifier.
The power amplifying
stage, which determines sound quality, consists of a single pair of
transistors, successfully eliminating the emitter resistance used by
conventional amplifiers to suppress overheating. The transistor output drives
the speaker directly, reproducing sound with less undesired character.
Frame
beam base chassis (FBB chassis).
A
frame beam base chassis has been developed for the stereo amplifier. By combining a conventional frame beam chassis
with a transformer base, providing high accuracy and stiffness, the frame is more
stabilized, reproducing better sound with less overall distortion.
A
preamplifier constructed of completely discrete stages.
This amplifier
employs a relay for signal switching to eliminate sound loss, and discrete
circuits for entire stages to optimize and upgrade the circuits.
Newly-designed
large speaker terminals.
The terminals of
this amplifier minimize sound quality deterioration. Y-lugs and speaker wires
can be tied securely.
Discrete
amplifier for exclusive use with headphones.
This
amplifier has a discrete amplifier used exclusively to drive headphones.
The impedance can be switched among LOW, MID, or HI to match that of the
headphones
