Mark Levinson ML-2 // Solid-State Monoblock Amplifiers / 1466/1704

The Mark Levinson ML-2 monoblock amplifiers are the audio equivalent of that quietly confident guy at the party who doesn’t say much but somehow commands all the attention. Launched in the late '70s, these amps are proof that you don’t need a million watts to make your speakers sit up and behave—you just need 25 watts of pure Class A power, a design that laughs in the face of efficiency, and a heat output that could double as your room's primary heating source.
