MOON at Pearl Audio
MOON amplifiers
Every MOON amplifier is engineered and built in Simaudio's own factory in Boucherville, Québec. We spent two days there in October 2026 listening to each of them in turn, and heard a clear step at every level.
Integrated amplifiers
A preamplifier and power amplifier in one chassis. The 250i v2 is the way in, with a phono input for a turntable. The 371 adds MiND 2 streaming, so loudspeakers are all it needs. The 641 brings the North Collection's amplifier design to a single box.
Preamplifiers
The 850P is MOON's two-chassis analog reference preamplifier, with a volume control built from an array of precision resistors. For a preamplifier with streaming built in, see the 491, 791 and 891 under Digital.
Power amplifiers
MOON's power amplifiers use a circuit Simaudio calls MDCA, which measures the error of the output transistors and cancels it without global feedback. The 461, 761 and 861 give 150, 200 and 300 watts per channel, and each can be switched to mono so that a second one makes a pair of monoblocks. At the factory we saw finished amplifiers run overnight under test before they are packed.
