Moon 850P Preamplifier

MOON 850P PREAMPLIFIER – THE ULTIMATE ANALOG HEART

The culmination of decades of experience in analog technology, the MOON 850P represents the brand's most advanced preamplifier to date. It is designed to be completely transparent - a component that disappears from the signal path, leaving the music in its purest form. Many reviewers have called it among the most musically revealing products ever.

HIGHLIGHTS

• Two-chassis design with full separation of power supply and audio circuitry
• i²DCf (Independent Inductive DC Filtering) with 40 independent stages
• Signal-to-noise ratio of a whopping 130 dB at full output
• Frequency response from 5 Hz to 100 kHz (±0.1 dB)
• Ultra-low distortion: 0.0005% THD and 0.0001% intermodulation
• 9 dB gain with ±10 dB adjustment per input
• 8 inputs (3 XLR, 5 RCA) and 4 outputs (2 XLR, 2 RCA)

TWO-CHASSIS CONSTRUCTION

The MOON 850P utilizes a sophisticated two-box design, where the power supply, digital control and display are isolated in one chassis, while all audio circuitry is housed exclusively in the other. This separation minimizes electrical interference and provides a signal path of extreme precision and purity.

Each integrated circuit in the signal path gets its own dedicated inductor via i²DCf technology, resulting in 40 independent filtering stages. This advanced approach reduces noise to unheard-of levels, ensuring that music is reproduced with natural warmth and remarkable detail.

SOUND AND PERFORMANCE

The 850P is designed to deliver an undistorted reproduction of the full spectrum of music. With a frequency response of 5 Hz to 100 kHz and a signal-to-noise ratio of 130 dB, music is presented in a calm, black background, where even the smallest details stand out clearly. Distortion is practically inaudible – measured at just 0.0005% THD – making the 850P a true reference in the high-end class.

Gain can be adjusted individually for each input by ±10 dB, allowing the preamplifier to be perfectly matched to different sources. All inputs can also be configured as “home theater ready”, bypassing the 850P’s volume control for full integration into a surround system.

DESIGN AND PRACTICE

Each of the two cabinets is made of solid aluminum and measures 47.6 cm wide, 10.2 cm high and 41.9 cm deep. The total weight of 67 kg is testament to the uncompromising construction.

The rear panel offers three balanced XLR inputs, five RCA inputs, and dual outputs in both balanced and unbalanced forms (fixed and variable). With an output impedance of just 50 ohms, the 850P ensures perfect compatibility with even the most demanding power amplifiers.

The MOON 850P Preamplifier is an uncompromising reference preamplifier, created for audiophiles who desire the most transparent and musical reproduction possible. With its unique construction, advanced power filtering and superior component selection, it delivers an audio experience that is among the absolute best in the world.
