stages. The result is the purest possible power for
these sensitive stages.
"Double" Balanced Voltage Gain Stages:
incoming signal from the preamplifier is received
using a special topology that eliminates the
customary feedback point on the inverting side of
the first stage differential amplifier, providing for a
truly balanced impedance at this critical juncture.
Fully Balanced Output Stage:
output devices (in two sets of ten complementary
pairs) are used in a bridged configuration. Thus
the output terminals do not reference ground at
all, and the Nº33H achieves near-perfect symme-
try in output currents resulting in effortless
precision and power.
Adaptive Biasing System :
ences both the instantaneous voltage and current
required by the load and determines the optimal
bias at each and every moment. This sophistica-
tion makes it impossible to reverse-bias the
outputs of any of the current Mark Levinson
amplifiers. This greatly reduces junction switch-
off transients and allows the amplifiers to achieve
the effortless, fatigue-free performance that Mark
Levinson amplifiers are known for.
Exhaustive Listening Tests:
tests were conducted to evaluate every critical
component in the signal path. Hundreds of hours
were invested at every stage of the design to
ensure that we squeezed every last drop
of performance from the design of the
Nº33H.

The Sound
The clarity and dynamics of the Nº33H Monaural
Power Amplifier are quite stunning, particularly
to those intimately familiar with the finest elec-
tronics. Additionally, the subjective noise floor
seems to drop significantly, revealing myriad
details in the music and a sense of soundstaging
and imaging that is without peer. The Nº33H
provides all the power and authority of a large
amplifier design, while retaining the finesse of a
smaller audiophile power amp.
Summary
The Nº33H Monaural Power Amplifier is the
absolute reference for audiophile listening. It
delivers effortless power in an elegant design that
conveys the entire musical experience. From the
subtlest nuance to the boldest crescendo, the
Nº33H will remind you why you fell in love with
music in the first place.
