    Description

    A Mark Levinson Amplifier for the Multi-Channel Age
    The Nº433, Mark Levinson’s first three channel, single-chassis power amplifier, is a significant milestone. It combines multichannel flexibility with the legendary quality and performance of our traditional single- and dual-monaural designs. The Nº433 is [Levinson’s] recognition that today’s home entertainment enthusiasts have a plethora of choices available to them, that a growing number of these choices use multi-channel sound to express artistic vision, and that today’s audiences deserve no less than the most truthful aural windows possible. The Nº433 is ideal for this demanding role.
    The Power of Three
    A three-channel amplifier is inherently flexible. It lets you power all front speakers (Left, Center, and Right) with identical circuitry and use your existing amplifier for the surround channels. Are you adding multichannel capability to an already-exceptional stereo music system? The Nº433 can provide power for a Center and two Surround speakers.
    Flexibility and Quality
    Fitting three separate amplifiers in an enclosure normally devoted to one or two presented significant challenges, including potential interference and heat dissipation issues far beyond those encountered in single- and dual-mono amplifiers.
    In addition, power amplifiers are core components of any high performance entertainment system. Power amplifiers play an inherently difficult role as they need to be authoritative enough to drive a wide variety of demanding speakers, yet transparent in order to preserve sonic neutrality.
    A Multi-Channel Standard
    The Nº433 is no exception to the demanding standards that Mark Levinson amplifiers have defined for more than three decades. Rated at 200 watts per channel into 8 Ohms and 400 watts per channel into 4 Ohms, the Nº433 is convection cooled and utilizes exposed internal heat sinks for each channel.
    With basic design directly traceable to [Levinson’s] Nº432 and Nº431 dual-monaural power amplifiers, the Nº433 boasts three massive 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 [Levinson’s] 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, [their] 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 individually, a practice that stands in sharp contrast to the generic computer-generated layouts used by many other companies. 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 excellence is the array of the ultra-high performance parts that populate [their] 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 physically inert and sonically neutral base.
    For the output sections, [they’ve] chosen bipolar transistors with the best performance characteristics 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 multichannel world.
