the Mark Levinson power amplifier tradition.
The power supply is the foundation that all of
the audio circuitry is built upon. Both amps
benefit from a massive, dedicated, independ-
ent linear power supply. Our ongoing
listening tests continue to confirm that abun-
dant clean power is essential for high
performance. Precise control of this power
reserve is the task of the amplifier's voltage
gain and output stage circuitry. Mark
Levinson amplifiers have always featured
precision circuitry designed to fully exploit
balanced signals. Rather than adding op-amp
buffers, or simply duplicating circuitry for
both halves of the balanced input signal as
many other amplifiers do, Mark Levinson
amplifiers feature an advanced, inherently
balanced topology for greater efficiency,
performance and sonic benefits. The Nº436
and Nº434 have power ratings of 350 and
125 watts into 8 Ohms, and 700 and 250
watts into 4 Ohms, respectively.
As with all Mark Levinson amplifiers, particu-
lar attention is paid to the layout and circuitry
connections. All circuit boards are laid out by
our engineers rather than by a computer
program. These new amplifiers outperform
their predecessors in part because of the
refinement of circuit layout. Additionally, the
ultra high performance parts that make up
the balanced circuits are able to work to their
full potential because they reside in the most
neutral circuit board material known as Arlon
25. The output stage of these new amplifiers
is similar to our other power amplifiers. The
matched output transistors continue to be the
best performing parts available for this appli-
cation and they are mounted directly to the
exposed internal black anodized aluminum
heat sinks.
The Nº436 and Nº434 set a new standard for
multi-channel and theater audio. Powerful,
elegant, and musical, these remarkable prod-
ucts combine stunning audiophile
performance and system flexibility without
compromise.
