About the No. 336

The Mark Levinson No. 336, introduced in 1998, is a dual monaural stereo power amplifier designed to combine massive power with the finesse of smaller amplifiers. It delivers 350 watts per channel into 8 ohms with a frequency response of 20Hz to 20kHz and total harmonic distortion of 0.5%. The amplifier features two large, independent power supplies—one for each channel—each with a high capacity, low noise toroidal transformer rated at 2450 VA and four 50,000 µF capacitors. It uses heavy oxygen-free copper bus bars for efficient power distribution and a truly balanced input topology that eliminates the need for an input buffer stage. The amplifier is quasi-class A biased, with all voltage gain stages operating in full class A for linearity and low distortion. It is stable down to 1 ohm speaker load and has a signal-to-noise ratio of 80 dB. The unit weighs 68.2 kg and measures 446 x 229 x 478.3 mm. Extensive protection circuitry safeguards the amplifier and connected speakers. The No. 336 is highly regarded for its solid, deep bass and realistic musical body, making it a favorite among audiophiles for driving demanding speakers.
