Overview
The VM220 monoblock power amplifier, which represents the capstone of this series, offers performance and features that go well beyond its companion products in the VS series. Its purpose is to provide the differential signal for true balanced operation, a first for this series. With both balanced and single-ended inputs (switch selected), the VM220 will be compatible with every Audio Research preamplifier.
The VM220 has classic tube sound virtues, but with greater extension, air and a robust bass response that goes far beyond anything you have heard from the VS series before.
