Mark Levinson N433 manual Levinson Difference, Summary

and totally independent linear power supplies, each consisting of a low-noise toroidal power transformer and a bank of low-loss capacitors to insure copious energy storage. Control of this power reserve is the task of the power amplifier’s voltage gain and output stage circuitry, an area in which Mark Levinson amplifiers have always excelled.

Balanced circuitry, another facet of our design expertise, is readily apparent in the Nº433. However, rather than take the less costly route of simply duplicating circuitry for both halves of the balanced input signal, our approach features an elegant new topology for greater efficiency, higher performance, and total sonic neutrality.

The Levinson Difference

All Mark Levinson power amplifiers benefit from extraordinary attention to circuit layout, signal routing, and connector placement. Engineers intimately familiar with each circuit’s operation design circuit boards indi- vidually, a practice that stands in sharp contrast to the generic computer-generated layouts used by many other compa-

nies. It is human insight and disciplined intuition that distinguishes the Nº433 – and all 400-series amplifiers

–and allows it to outperform its predecessors.

Another factor in Mark Levinson excel- lence is the array of the ultra-high performance parts that populate our balanced circuits. Even the circuit board itself is of prime importance as it allows these parts to perform ideally under a wide range of

temperatures and humidity. Here, the advanced material Arlon® provides a physical- ly inert and sonically neutral base.

For the output sections, we’ve chosen bipolar transistors with the best performance charac- teristics and mounted them directly on the exposed internal black-anodized aluminum heat sinks for maximum heat dissipation.

In Summary

With its flexible triple-monaural design and unique combination of brute force and finesse, the Nº433 perfectly augments the 400 series of amplifiers.

Accuracy. Reliability. Flexibility. The Nº433 places Mark Levinson firmly in the multi- channel world.
