The MOON LP3 was simple solution for those wishing to indulge in high quality analog playback. Based on its big brother, the MOON LP5.3, the LP3 represented a significant step forward in affordable phono preamplifier design. Great detail was paid to noise levels and dynamic range, making it one of the quietest phono preamplifiers at its price point. Sonically, it portrayed 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 MOON LP3 was its flexibility with respect to end-user adjustments for resistance and capacitance loading as well as gain; changing your cartridge would not force you to change your phono preamplifier. As well, the LP3 was housed in an ultra-compact, rigid all-aluminum chassis with a brushed and anodized front panel.

Technical aspects

End-user adjustable impedance loading (100 and 47k ohms)
End-user adjustable capacitance loading (0pF and 100pF)
End-user adjustable gain for moving magnet (40dB) & moving coil cartridges (60dB)
Two-layer PCB tracings 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
Inductive DC Filtering for a significantly lower noise floor
Accurate matching of military-grade components with ultra-tight tolerances using surface-mount
technology for extremely short signal paths
 Compact, rigid all-aluminum chassis with gold-plated RCA connectors.
