Simaudio 810LP Moon Phono Preamplifier

The ultimate phono preamplifier
Over time the soundstage got even deeper and incredibly wide, with the unerring ability to clearly place and delineate individual musicians within a fully fleshed-out acoustic.

Suspension which eliminate microphonics for absolute best analog sound
In terms of black backgrounds, top-to-bottom transient response, image definition, dynamic contrasts at both ends of the scale, and rhythm n pacing, the MOON 810LP was worth its considerable price. It was a model of rhythmic and spatial organization. 
Michael Fremer, Stereophile
