The MOON 810LP represents an "all out assault" on phono preamplification resulting from 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 MOON 810LP to work with virtually any available phono cartridge. 

The oversized power supply, is housed in an isolated steel enclosure 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. On the actual audio circuit, there are 4 stages of M-LoVo (MOON low voltage DC regulation circuit).

Made In Canada.

Available in Black, Silver or Two-Tone Finishes.

Design Features:

  • 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 – 24 stages in all.
  • The dedicated audio circuit board is mounted on a 5-point gel-based floating suspension, derived from our M-Octave technology, originally developed for our reference 850P Preamplifier.
  • Fully compatible with 820S external power supply.
  • Customized parts include metallized polypropylene film capacitors with very tight tolerances of 1%.
  • Four-layer PCB tracings with dedicated ground and power planes using pure copper for low impedance characteristics.
