MOON 310LP Balanced Phono Preamplifier

The MOON 310LP lets you experience a blacker background and even more lifelike musical reproduction than ever before. Combine this with all the MOON hallmarks: clean, powerful, fast extended bass, an open midrange and airy extended high frequencies: MOON’s mid-priced phono preamplifier performance is a major leap forward like nothing else in this price range. The MOON 310LP is housed in a very stylish half-width chassis which both visually enhances the unit and makes it easy to physically sit within your system. As you would expect from MOON the 310LP has a fully balanced output stage via XLR sockets.

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 (i) upgrade from the sonics of the original (flat facia) 310LP and (ii) reduce the noise floor of its onboard power supply. Consequently, this diminishes the need for an external power supply.

Design Features

  • Large isolated power supply on a separate circuit board using a toroidal transformer with 2 stages of voltage regulation.
  • Single-ended RCA and Balanced XLR output connectors.
  • Can be driven with a compatible external power supply.
  • Power supply voltage regulation includes i 2 DCf (Independent Inductive DC Filtering); 1 inductor for each and every IC 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 dramatically improved signal-to-noise ratio.
  • Symmetrical circuit design with accurate matching of the very finest quality electronic components.
