The  MOON LP 5.3 represents a significant step forward in phono 

preamplifier design. Particular attention has been paid to noise levels

and dynamic range, making the LP 5.3 one of the quietest phono pream-

plifiers ever, on par and even superior to many models at significantly

higher price points. Sonically, it portrays all

the Simaudio hallmarks: clean, powerful,

fast and extended bass combined with an

open midrange and airy extended high 

frequencies. One of the strengths of the 

LP 5.3 is its extensive flexibility with

respect to end-user adjustments. The balanced outputs allows you to

take full advantage of connectivity to a balanced preamplifier or inte-

grated amplifier for a significant improvement in noise floor, dynamics

and midrange transparency. Unlike most of the competition, which

either uses mass-manufacturing tech-

niques or a circuit mounted in a basic 

folded metal box, the LP 5.3 is housed in a

custom-made, sturdy chassis with a 3/8”

brushed and anodized front panel.

End-user adjustments for capacitance loading, resistance loading and gain level to extract exceptional performance from virtually all high quality

phono cartridges • End-user adjustments to alternate between the RIAA and IEC equalization curves • Isolated and shielded power supply on a 

separate circuit board based around an ultra-low noise toroidal transformer • An extremely short signal path for a faster transient response

• Single-ended RCA and balanced XLR output connectors • Optional external power supply • Power supply voltage regulation includes i

DCf

(Independent Inductive DC Filtering) derived from the Evolution Series for increased dynamic range • Four-layer PCB tracings with dedicated ground

and power planes using pure copper for low impedance characteristics. The advantages are better circuit layouts resulting in much shorter signal

paths and a vastly improved signal-to-noise ratio • Rigid chassis construction to minimize the effects of external vibrations • A symmetrical circuit

design with accurate matching of the very finest high quality electronic components • Designed to be powered up at all times for optimal performance

• Low operating temperature for a longer than normal life expectancy.
