The MOON P 5.3 Preamplifier follows in the footsteps of the legendary, award
winning P-5. Representing a genuine leap forward from earlier MOON series
preamplifiers, the P 5.3 employs numerous advancements from our Evolutions
series. Call it trickle-down technology if you will -“ the audio circuitry is based
on the
MOON P-7 preamplifier. The result is incredible sonic transparency,
a dead-quiet black background and genuine ease-of-use. Offering balanced circuitry, 5 line-level inputs and an optional internal phono section with adjustable
gain, resistance and capacitance, the
MOON P 5.3 pushes the envelope to new
heights with respect to the price-to-performance ratio.
With features such as a large and easily legible display, an IR input for external
control, a 12 Volt trigger output, a user configurable Home-Theater input and a lux-
urious industrial-grade build quality, the
MOON P 5.3 will provide for many years of
listening pleasure and unprecedented reliability as the control center for your
music system. The
MOON W 5.3
Power Amplifier boasts 150 watts per channel into 8 ohms and
300 watts into 4 ohms of continuous power output. It can easily be configured for
mono operation, yielding a robust 500 watts of power. This heir apparent to the
world-reknowned
W-5.3 encompasses our award winning Advanced
Rennaisance amplifier technology. The result is a warm, grain-free sound with
tight, authoritative bass, ultra-fast transients and incredible timbral accuracy. The
MOON W 5.3 will sound effortless at any output level.
A two-channel or multi-channel system built around the
MOON W 5.3 will provide
for many years of high-performance operation and unprecedented reliabilty.
Housed inrugged yet elegant chassis, with a 12 Volt trigger input and balanced
audio circuitry, the
W 5.3 represents the most affordable entry into the universe of MOON high-performance amplification. Simaudio Ltd. has been designing and manufacturing innovative, leading-edge
audio and video products since 1980.
MOON products have been globally
recognized for their world-class performance, garnering numerous accolades
for this outstanding achievement. Our products are engineered and built in Canada,
utilizing advanced, efficient, "green" assembly techniques with strict quality control.
Furthermore, our manufacturing processes are part of our philosophy, whereas the
high quality and long-life of
MOON products are the best way to preserve our
environment, avoiding premature obsolesence. MOON products meet or exceed all
international requirements for safety, performance and durability. At Simaudio, great
music matters. However, great music for a lifetime matters most.

Technical information
The frequency response curve in top figure is virtually flat throughout, and beyond,
the entire audible range as a result of the DC-Coupled circuit employed on
our MOON amplifiers. Conversely, the frequency response curve of a traditional
AC-Coupled amplifier design is far from perfect, as seen in the bottom figure; both low
and high frequencies in the audible range are noticeably diminished.
Deeper, more accurate and articulate bass ...
You will clearly distinguish
between a double-bass and an electric bass in a heart-beat.
The three response curves in figure 3 demonstrate (i) a theoretically perfect transform
er regulation factor of 0% (green), whereby voltage remains stable regardless of the
current draw, (ii) a remarkably low regulation factor of 3% (black), found in
MOON
W 5.3 amplifier, where the voltage drops very slightly as the current draw increases
and (iii) a typical regulation factor of 10% (red), whereby, as the current draw increas-
es, power supply voltage drops significantly, as found in most competing amplifier
designs.
Powerful musical passages are faithfully and
thoroughly reproduced in an effortless manner.
Without the blocking capacitors at the amplifiers input, sound quality is improved as
the phase-shift caused by these capacitors is eliminated. Frequency response in
the bass region approaches 0Hz. As well, by removing all capacitors from the direct
audio signal path, ultimate soundstage focus is attained with less smear or blur.
Apower supply transformer with a tight regulation (low) factor assures that
power into more difficult speaker loads will be delivered closer to the theoretical
ideal. These transformers are significantly more expensive, but are the only way to
assure stability and consequently excellent sound quality under all conditions. Precision matched Bipolar output devices
which offer both high-current and superb
linearity throughout the entire audio
frequency spectrum (8 per channel). A 12 Volt trigger for remote operations.
Pure copper circuit board tracings with
extremely low impedance characteristics.
A custom, oversized proprietary toroidal
transformer design with lower magnetic,
electrical and thermal loss, yielding an
Improved power transfer and lower
regulation factor, resulting in increased
current speed and better dynamics.
- IR input for external control (all discrete codes)
and 12 Volt trigger output.
- An exceptionally short signal path measuring
only 10 inches in length from the rear panel's
input to output connectors, yielding a much
faster transient response.
- Open loop zero feedback circuit topology
using absolutely no capacitors anywhere in
the audio signal path.
- One single-ended audio input, of your choice,
which functions as a pass-through, bypass-
ing the gain stage to accommodate a compo-
nent such as a home-theater processor,
whose own volume control is used instead.
