Moon 461 Power Amplifier

The 461 is the most powerful model in the Compass Collection, an analog power amplifier Simaudio built for accuracy, control, and flexible system configurations.

It adapts the MDCA architecture Simaudio pioneered in the North Collection down to a dual-mono layout with two separate MOON Hybrid Power supply modules, one per channel, to keep crosstalk low.
