MOON 810LP Phono Preamplifier The MOON 810LP Phono Preamplifier is a true reference-grade, dual-mono phono stage built for listeners who want uncompromising analog realism and the flexibility to dial in virtually any cartridge. Its fully balanced differential topology, ultra-low-noise regulation, and meticulously optimized signal path deliver an inky-black background, precise imaging, and effortless dynamics—so your records sound bigger, cleaner, and more lifelike. For cartridge matching, the 810LP provides extensive DIP-switch tuning with 64 impedance settings (12.1Ω–47kΩ), 16 capacitance settings (0pF–1120pF), and 16 gain settings (40dB–70dB), plus selectable RIAA or IEC equalization for system and record optimization. A 5-point gel-based floating suspension helps minimize microphonics and vibration effects, while premium parts and a four-layer PCB preserve nuance and timing. It also supports use with the MOON 820S external power supply for those who want to push performance even further. The Moon 810LP is part of ListenUp's MOON Phono Preamplifier Collection.

The 810LP is designed to work with both moving magnet (MM) and moving coil (MC) cartridges, with broad gain and loading adjustability to match low, medium, and high output designs. How do I match the 810LP to my cartridge? Cartridge matching is done via bottom-panel DIP switches, giving you 64 impedance settings (12.1Ω–47kΩ), 16 capacitance settings (0pF–1120pF), and 16 gain settings (40dB–70dB). What’s the benefit of selectable RIAA vs IEC equalization? RIAA is the standard playback curve, while IEC adds subsonic filtering behavior (below 20Hz) that can help reduce infrasonic bass energy from warped records or sensitive speaker setups. Does the 810LP offer balanced connections? Yes. It provides both balanced XLR and single-ended RCA inputs and outputs, making it easy to integrate into fully balanced or traditional systems. How quiet is the MOON 810LP? It’s engineered for extremely low noise, with signal-to-noise performance reaching 115dBr at 40dB gain and maintaining strong noise performance even at higher gain settings. Can I leave the 810LP powered on all the time? It’s commonly recommended to leave it powered for optimal performance; after power cycling, it may require some playing time to return to peak performance. Is there a recommended starting point for MM vs MC cartridges? For many MM cartridges, typical starting points are higher impedance (often near 47kΩ) and moderate gain, while MC cartridges often benefit from lower impedance loading and higher gain—fine tuning by ear is encouraged. Can the 810LP be upgraded later for even higher performance? Yes. It is compatible with the MOON 820S external power supply, which can be added to further enhance system performance.
