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 counter- parts. 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. But technology continues to advance, often relentlessly, and Mark Levinson products advance with it.
The No53 Reference monaural power amplifier is a landmark, the first-ever switch- ing power amplifier from the Mark Levinson brand, and the first Mark Levinson power amplifier to earn the Reference designation since the No33 in 1994.
Switching power amplifiers are not new, and although they offer several advantages over linear designs – more power, increased efficiency, compact dimensions, lower weight and less heat dissipation – they’ve been generally maligned by audiophiles for inferior sound quality. The audiophiles are right – there are significant technical limitations inherent in conventional switch- ing designs. But Mark Levinson engineers have successfully overcome the limitations with the No53.
