stages. The result is the purest possible power for these sensitive stages.

“Double” Balanced Voltage Gain Stages: The 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: A total of 40 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 : This system refer- 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: Extensive listening 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.

Comprehensive Protection Circuitry:

other Mark Levinson amplifiers, will shut them- selves down if they sense any of a number of fault conditions which could cause damage to either themselves or to the loudspeakers.

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.
