The Nº 431, 432, and 433 multi-channel power amplifiers incorporate the same attention to technical design and sonic detail as other Mark Levinson products. They also represent extraordinary value. The two-channel Nº 431 produces 200 watts continuous power per channel into 8 ohms and doubles that into 4 ohms. The more powerful Nº 432 delivers 400 or 800 watts per channel into 8 and 4 ohms respectively. The triple monaural Nº 433 outputs 200/400 watts continuous into 8 and 4 ohms from each of its three channels. Choose according to your needs. All deliver the same outstanding Levinson quality.
The physical and sonic properties of the Nº432 and Nº431 are built upon the Mark Levinson power amplifier tradition. The power supply is the foundation that all of the audio circuitry is built upon. Each channel benefits from a massive, dedicated, independent linear power supply. Our listening tests continue to confirm that abundant clean power is essential for high performance. Precise control of this power reserve is the task of the power amplifier’s voltage gain and output stage circuitry. Mark Levinson power amplifiers have always featured precision circuitry designed to fully exploit balanced signals. Rather than simply duplicate circuitry for both halves of the balanced input signal as many power amplifiers do, our power amplifiers have featured an advanced topology for greater efficiency, performance and sonic benefits. The Nº432 and Nº431 continue this practice. Though similar to the Voltage Gain circuit in the 300 series power amplifiers that they replace, this new generation of power amplifiers features a more elegant topology closely related to the Nº436 and Nº434 mono power amplifiers. As with all Mark Levinson power amplifiers, particular attention is paid to the layout of circuitry and precise location and routing of connections. All circuit board layout is performed by our engineers rather than by a computer program. These new power amplifiers outperform their predecessors in part because of the refinement of circuit layout. Additionally, the ultra-high performance parts that make up our balanced circuits are able to work to their full potential because they reside in the most neutral circuit board material we know of: Arlon®. The matched output transistors continue to be the best performing parts available for this application and they are mounted directly to the exposed internal black anodized aluminum heat sinks.
