Mark Levinson is showing the No433 power amplifier. Based on the No432 and No431 power amplifiers, the No433 is a triple-mono 200-watt power amplifier with all of the authority and finesse that distinguish Mark Levinson products. Featuring a compact chassis and remarkable bottom-end heft and weight, the No433 takes command of the music with astounding confidence, dynamics and ease. Like all 400 series power amplifiers, the No433 doubles its rated 8-ohm power at 4 ohms. Combine that with massive independent power supplies for each channel, and the No433 is an appropriate companion for virtually any loudspeaker. The No433 is entirely convection cooled, and therefore does not require fans. The new amplifier features individual heat sinks for each channel to maintain a safe operating temperature while delivering continuous output power. In addition, a balanced voltage-gain circuit allows the No433 to generate more precise signals with lower noise. The balanced circuit includes ultra-high performance parts that allow this advanced design to reach its full potential. The 400 series power amplifiers represent significant advancements compared to their predecessors. They are better sounding, more powerful, physically smaller, rack mountable, and the best value to date in Mark Levinson amplifiers, as well as the first series to feature an amplifier with three channels. The multi-mono 400 series power amplifiers effectively replace the popular 300 series as the entry level Mark Levinson power amplifiers. The triple-mono No433 is currently available.
