MOON Evolution Series 810LP Phono Preamplifier

  • M-Octave Damping technology
  • 4 stages of the newly developed M-LoVo (MOON Low Voltage) DC regulation circuit
  • Adjustable impedance loading - 64 available settings from 12.1ohms to 47kohms
  • Adjustable capacitance loading - 16 available settings from 0pF to 1120pF
  • Adjustable gain settings - 16 available settings from 40dB to 70dB

The MOON 810LP is the company's first Evolution Series phono preamplifier. The dual-mono fully balanced differential design features a combination of customized parts in an ultra-refined audio circuit which is mounted on a floating suspension and fed by a unique power supply. Its highly configurable nature selectable gain, impedance loading, capacitance loading and equalization curves - is accomplished using DIP switches located on the bottom panel. These switches are located directly in line with the circuit at optimal locations to yield the shortest possible signal path. These adjustments, in conjunction with an excellent overload margin, allow the 810LP to work with virtually any available phono cartridge.

The oversized power supply, located within the main chassis, is housed in an isolated enclosure that is constructed from satin-coated 14-gauge steel to eliminate all traces of AC artifacts. Within this enclosure is a high quality toroidal transformer, a "pi-type" filter to reduce AC transmission noise and multiple stages of voltage regulation. Finally, on the actual audio circuit, there are 4 stages of M-LoVo an all new proprietary MOON low voltage DC regulation circuit. Combining all of these factors, the MOON 810LP's power supply exceeds the performance of a battery power supply with respect to both audio signal-to-noise ratio and voltage regulation.

"For many years Simaudio has had a strong desire to offer the very finest phono preamplifier, based on available technologies. We envisioned a design with absolutely no restrictions; the ultimate goal being to transport all of the emotion from the artist, sound engineer and producer in the recording studio to your living room. With the MOON 810LP we have accomplished this and much more. Listen and feel for yourself how the power, the emotion and the soul of the music will reach you in ways like never before."

    -- Jean Poulin, CEO Simaudio Ltd.

Significant design features:

  • The dedicated audio circuit board is mounted on a 5-point gel-based floating suspension which is derived from M-Octave Damping technology, originally developed for the reference MOON 850P Preamplifier
  • 4 stages of the newly developed M-LoVo (MOON Low Voltage) DC regulation circuit, a highly sophisticated circuit made up of a clever combination of IC’s and discrete parts that is virtually free of noise, yielding an exceptionally fast, precise, and stable DC voltage. The result is a power supply with a noise floor of -150dB related to 1.0V, DC - 100kHz
  • Adjustable impedance loading - 64 available settings from 12.1 Ohms to 47k Ohms
  • Adjustable capacitance loading - 16 available settings from 0pF to 1120pF
  • Adjustable gain settings - 16 available settings from 40dB to 70dB
  • Selectable equalization curves for both the RIAA and the IEC standards
  • Power supply voltage regulation includes i-DCf (Independent Inductive DC Filtering); there is one inductor dedicated to each integrated circuit type component (DAC, Op-Amp, etc.) in the audio circuit's signal path - 24 stages in all
  • Customized parts include metallized polypropylene film capacitors with very tight tolerances of 1%
  • 4-Layer PCB's with pure copper tracings for a much shorter signal path; This results in greater sonic accuracy and a dramatically improved signal-to-noise ratio
  • Power supply featuring a "pi-type" filter comprised of 40,000uF of capacitance and dual choke inductance (2x 200mH)
  • 12 Volt trigger input and output for remote operation
  • Ultra rigid chassis construction to minimize the effects of external vibrations
  • Accurate matching of the very finest quality electronic components in a symmetrical circuit design
