The Mark Levinson No. 33H isn’t just an amplifier—it’s a monument to excessive audiophile indulgence. Weighing in at nearly 175 pounds a piece, these “space saving” monoblocks are less “amps” and more “structural reinforcements.” Your back will hate you for buying them, but your ears? Oh, they’ll love you forever.

Solid-state monoblock power amplifier.
Rated continuous-power outputs: 150W into 8 ohms (21.8dBW), 300W into 4 ohms (21.8dBW), 600W into 2 ohms (21.8dBW), 1200W into 1 ohm (21.8dBW).
Frequency response: 20Hz-20kHz, <0.5%
THD. S/N ratio: better than 80dB (ref. 1W), better than 105dB (ref. full output).
Input impedance: 100k ohms balanced, 50k ohms unbalanced.
Output impedance: <0.05 ohms, 20Hz-20kHz.
Damping factor: greater than 800 at 20Hz.
Input sensitivity: 130mV for 2.83V output, 1.59V for full-rated output.
Voltage gain: 26.8dB.
Typical power consumption: 540W ±5% at idle, 210W ±5% in standby.
Mains voltages: 100V, 120V, 200V, 210V, 220V, 230V, or 240V AC mains operation at 50 or 60Hz, set at factory.
