310LP Phono Preamplifier

the abso!lute sound's 2023 Editor's Choice Winner

for Best Phonostages between $2,000-$3,000 

  • Balanced circuitry
  • Internal settings for: loading, capacitance and equalization curve
  • Up to 72dB of gain
  • Both single-ended (RCA) and balanced (XLR) outputs
  • 7.5" (19 cm) wide

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.
  • A symmetrical circuit design with accurate matching of the very finest high quality electronic components.

The following accessories should be included inside the box with your phono preamplifier:

  • AC power cable
  • Owner’s manual
  • Warranty and product registration information (USA and Canada only)

Best Phonostages $2000 - $3000
LOW NOISE FLOOR
Experience a blacker background and even more lifelike 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 MOON 310LP is housed in a very stylish half width chassis.
ULTRA FLEXIBLE
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 chose from two different equalization curves; either the RIAA curve or the IEC curve.
BALANCED OUTPUT
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.

Expert Insight

Design that stands the test of time. The 310LP is a top performer with “quiet operation” and a “neutral signature.
