Introduction
Thank you for selecting the MOON 610LP Dual-
Mono Phono Preamplifier as a part of your
music/cinema system. This component has been
designed to offer state-of-the-art high-end
performance in an elegant package, while retaining
all the sonic hallmarks on which Simaudio has made
its reputation. We have spared no effort to ensure
that it is amongst the finest phono preamplifiers
available. We have been building high-performance
audio equipment for over 30 years, and the
know-how gained through our cumulative
experience is an important reason why MOON audio
components are so musically satisfying.
The performance of your 610LP will continue to
improve during the first 500 hours of listening. This
is the result of a “break-in” period required for the
numerous high quality electronic parts used
throughout this phono preamplifier.
Before setting up your new MOON 610LP, we
encourage you to please read this manual
thoroughly to properly acquaint yourself with its
features. We hope you enjoy listening to the
MOON 610LP Phono Preamplifier as much as
the pride we have taken in creating this fine audio
product. We understand the power and emotion of
music and build our products with the goal of
faithfully capturing these elusive qualities.

Your MOON 610LP Phono Preamplifier incorporates many significant design features to achieve its “world
class” level of performance. This is an abbreviated list of the more important features:
The oversized power supply, located within the main
chassis, is housed in an isolated enclosure that is
constructed from satin coated 14-gauge steel to
eliminate all traces of AC artifacts. Power supply featuring
a "pi-type" filter using 40,000uF of capacitance and
dual choke inductance (2x 200mH). The result is a
power supply with a noise floor of -150dB related to 1.0V,
DC - 100kHz.
Power supply voltage regulation includes i 2 DCf
(Independent Inductive DC Filtering); 1 inductor for each
and every chip (i.e. OpAmp, etc.) in the audio circuit’s
signal path – 24 stages in all.
Adjustable impedance loading - 64 available settings
from 12.1Ω to 47kΩ
Adjustable capacitance loading - 16 available settings
from 0pF to 1120pF
Adjustable gain settings - 16 available settings from
40dB to 70dB
Selectable equalization curves for both the RIAA and
the IEC standards
Customized parts include metallized polypropylene
film capacitors with very tight tolerances of 1%
The shortest possible signal path for a faster
transient response and the lowest possible noise
floor.
Four-layer PCB tracings with dedicated ground and
power planes using pure copper for low impedance
characteristics. The advantages include better circuit
layouts resulting in a much shorter signal path and a
vastly improved signal-to-noise ratio
Optional external power supply.
Ultra rigid chassis construction to minimize the effects
of external vibrations.
