Moon 641 Integrated Amplifier

Simaudio positions the 641 as the centerpiece of a North Collection system, housing a preamplifier and power amplifier in a single chassis built to showcase the collection's design and current Moon technology.

It runs on Simaudio's MDCA (Moon Distortion-Cancelling Amplifier) topology, built to operate outside the signal path without global feedback, in a dual-mono layout with a 4.3 inch display and a MOONLink port for coordinating with other North Collection components.
