MOON 850P Dual Chassis Reference Balanced Preamplifier


MOON 850P Dual Chassis Reference Balanced Preamplifier

The MOON 850P Preamplifier 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 transparent, quietest, most accurate and uncoloured preamplifier.

the ultimate analog preamplifier

“It’s the most transparent preamp – or audio component of any sort – that I’ve heard.” – Brian Damkroger, Stereophile

Moon's most advanced preamplifier to date

“This is a rare component in the way it disappears, revealing nothing but the music carried through it. I’ve yet to hear one that reveals more music.”
– Jeff Dorgay, TONEAudio

product 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.
