The MOON 850P is the most advanced MOON preamplifier to date. Extensive research and development, coupled with recent advancements in electronic parts, have provided us with the foundation to design what may very well be the quietest, most accurate and uncolored preamplifier.

Targeted to the discerning listener who desires uncompromising musical reproduction, the 850P features numerous proprietary technologies such as our new M-Octave Damping damping system that eliminates the sonically degrading effects of microphonics by mounting the main audio circuit on an 8-point floating suspension. The result is a more natural, liquid and lifelike sound. Since listening environments are typically loaded with acoustically induced vibrations that originate from the loudspeakers, we use M-Octave to isolate the MOON 850P from these microphonic-causing vibrations, allowing you to hear more music, exactly the way it was recorded.


A sensation so lifelike, you'll feel as if the music is coming from a live source.

Other in-house technologies include (i) i²DCf power supply voltage regulation, (ii) M-Ray volume control, with a phenomenal 530 steps, allowing for an extremely precise level adjustment, (iii) SimLink and (iv) M-Lock, just to name a few, as well as an RS-232 connection, IR port and 12 Volt triggers for custom-install environments. Finally, a plethora of user selectable cosmetic options are available at the time of purchase.

Design features
  • 2-chassis design with 1 chassis housing the power supply, digital controller circuitry, software processing & the LED display. The other chassis contains ONLY audio circuitry.

  • 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 – 40 stages in all.

  • Gain offset adjustment of ±10dB for each line input.

  • Each line input is fully configurable to be “home theater ready”, whereby the 850P’s volume control is bypassed.
