Moon by Simaudio 861 Stereo Power Amplifier — Two-Tone Finish
Simaudio builds amplifiers in Saint-Laurent, Quebec, and the 861 sits at the upper end of their Evolution line — a dual-mono stereo power amplifier built around fully balanced differential topology, separate power supplies for each channel, and the class of component selection that Simaudio applies only to their reference-tier builds. The two-tone finish — silver faceplate, contrasting chassis — is the aesthetic that defines Moon's high-end range and makes their equipment immediately identifiable in a rack.
The circuit design is Simaudio's highest-development work outside their Statement monoblock program: fully differential balanced signal path from XLR input to output stage, with unbalanced RCA inputs also available. The power supply is oversized and independently regulated per channel — Simaudio's position is that proper power delivery is not a secondary consideration but the foundation the rest of the circuit depends on.
Pre-owned in [condition notes here]. A Moon 861 in good condition is increasingly hard to find — Simaudio builds to a service life measured in decades, and owners tend to hold them.
