MOON by Simaudio



A step up from MOON’s 110LP v2, the 310LP is – refreshed and upgraded in 2017 – is another exceptional phono preamplifier. Still compact, but fully re-designed to both improve audio quality and to integrate an ultra low noise power supply. Fully adjustable for moving coil and moving magnet cartridges.

Improving on already great performance is no easy task. When an audio component works so well, why change it? Thanks to various emerging technologies, several design enhancements became available, opening up a window of opportunity to upgrade the sonics of the original 310LP and reduce the noise floor of its onboard power supply. Consequently, this diminishes the need for an external power supply.

The result is an even quieter phono preamplifier which means you will experience a blacker background and even more life-like musical reproduction. Combine this with all the MOON hallmarks: clean, powerful, fast extended bass an open midrange and airy extended high frequencies, mid-priced phono preamplifier performance has just taken a major leap forward. To further these significant enhancements, the 310LP is housed in a very stylish half width chassis.

Within the confines of this chassis are numerous end-user adjustments for resistance loading, capacitance loading and gain level. Going one step further, you can even choose from two different equalisation curves: RIAA or IEC.

Rounding out this package are balanced outputs that allow you to take full advantage of connectivity to a balanced preamplifier or integrated for a significant improvement in noise floor, dynamics and midrange transparency.




  • Large isolated power supply on a separate circuit with 2 stages of voltage regulation.
  • An extremely short signal path for a faster transient response.
  • Single-ended RCA and Balanced XLR outputs.
  • Can be driven with a compatible external power supply.
  • Power supply voltage regulation includes i²DCf (Independent Inductive DC Filtering). There is one inductor dedicated to each integrated circuit type component (DAC, Op-Amp, etc.) in the audio circuit’s signal path; 2 stages in all
  • Power supply features custom MOON electrolytic capacitors.
  • 4-Layer printed circuit boards with pure copper tracings for a much shorter signal path. This results in greater sonic accuracy and a dramatically 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.
  • Low operating temperature for an ultra-long life expectancy.
