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
N
433. However, rather than take the less
º
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 N
433 –
º
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.
advanced material Arlon
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 N
433 perfectly augments the
º
400 series of amplifiers.
Accuracy. Reliability. Flexibility. The N

channel world.
