REINVENTING THE POWER AMPLIFIER – AGAIN The Mark Levinson® ML-2 power amplifier, introduced in 1972, flew directly in the face of conventional wisdom, demonstrating beyond all doubt that a solid-state amplifier could outperform its vacuum-tube counterparts. A 25-watt pure Class A monaural power amplifier, the ML-2 set Mark Levinson engineers on a path – designing and building the world’s best-performing linear power amplifiers – they’ve been traveling ever since.

2MHz, delivering two major sonic advantages. First, it pushes the fundamental switching noise and associated harmonics so far above the limit of human hearing that they have no direct effect on sound quality. (In fact, most audio testing devices can’t even measure such frequencies.) Second, it allows for easier removal of switching noise from the signal with much gentler notch filters, which have no negative effect on the crucial audio band.

This side view shows the four different compartments of the amplifier: the power supply section at the bottom, the middle section with the four amplifiers, the top section with the control circuitry (modulator), and a separate enclosed box (top left) that houses the analog input board.
