Refined Power Amplification
In order to deliver a clear and comfortable audio image, it’s
vital that sounds of different frequencies arrive at the listening
position simultaneously. Power amplification circuits feature
original topology that’s carefully tuned for phase accuracy,
wide-spectrum signal reproduction, and natural transient
response. Fitted with hand-selected audio-grade parts, the
amplifier contributes to lifelike and involving sound quality.
Nuanced Musicality Delivered with Discrete
SpectraModule
™
Discrete SpectraModule boasts a slew rate of over 500 V/µs,
significantly higher than competitive products that use a
standard IC chip. High-voltage performance enables flat
linearity into the megahertz range for full-bandwidth signal
reproduction. This is important not only for natural transients
expressing the nuances in
music with freshness and
vitality, but also for accurate
definition of instruments
ranged around a larger and
more realistic soundstage.
Dedicated MM/MC Phono Circuit Board
The A-9150 makes your records sound better than ever. A
gold-plated phono input supports signals from either MM or
MC cartridges fitted to your choice of turntable. Separate
phono circuit board has dedicated equalizers served by a
top-quality customized head
amp, which operates in
discrete configuration for
MC signals. Together with
analog power amplification,
this high-grade phono input
design expresses the depth
and vitality of music on vinyl.
Customized High-Current Transformer and
Custom Audio-Grade Capacitors
Current has great influence on sound quality. High current is
required for a better grip on the speaker transducers,
improving control and accuracy. A customized high-output
transformer and two huge custom capacitors inside the
A-9150 deliver current through discrete output-stage
transistors that are kept cool by an aluminum heat sink.
Speakers react instantly, with throw-range precisely controlled
for accurate articulation even through dynamic and complex
musical passages.
DIDRC Filter and Hi-Grade DAC for Natural Sound
Distortion in the ultra-high-frequency spectrum can have a
noticeable impact on the character of audible sound. Even
the best D/A converters introduce some noise to the signal,
and that noise is amplified, distorting the sound you hear.
DIDRC Filter completely erases ultra-high-frequency noise.
Performance is optimized for digital music with an undistorted
frequency response extending far above the range of
audibility. Combined with a premium 768 kHz/32-bit DAC,
you can enjoy a greater sense of realism from digital sources,
with none of the unnatural “synthesized” feeling sometimes
produced by digital processing.
Solid Build with High-grade Terminals
A peek under the hood tells you what to expect from the
A-9150. Held in place by a flat chassis that tames resonance,
the digital audio board is isolated from the analog circuitry.
L/R channels are symmetrical to equalize signal path-lengths
and minimize stereo playback errors.
Coaxial digital inputs, phono input,
speaker posts, and RCA line inputs
are gold-plated and of excellent
quality. Finished with an aluminum
front panel and volume control, the
A-9150 presents as a component
built to last.
