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.

No. 33H specifications

The Mark Levinson No. 33H is a high-end audio amplifier designed to deliver unparalleled sound quality and performance. Renowned in the audiophile community, this amplifier exemplifies the convergence of cutting-edge technology, superior craftsmanship, and obsessive attention to detail. With a power output of 300 watts per channel into 8 ohms, and a remarkable 600 watts into 4 ohms, the No. 33H is engineered to drive even the most demanding loudspeakers with authority and finesse.

One of the standout features of the Mark Levinson No. 33H is its dual-mono architecture. This design isolates the left and right channels to eliminate crosstalk and ensure that each channel operates without interference. This meticulous attention to channel separation results in an expansive soundstage, where each instrument and vocal is rendered with crystal clarity and precision.

The use of proprietary technologies is another defining characteristic of the No. 33H. The amplifier employs a sophisticated linear power supply that utilizes a toroidal transformer to deliver consistent and stable power to the output stage. This not only enhances the amp’s performance but also minimizes noise and distortion, allowing for a more immersive listening experience. Additionally, the No. 33H incorporates advanced Class AB topology, blending the best qualities of both Class A and Class B amplifiers, providing rich, warm sound while maintaining dynamic efficiency.

The No. 33H is also equipped with a unique heat management system. The amplifier features extensive heatsinking and an intelligent thermal monitoring system to ensure optimal performance without overheating. This ensures longevity and reliability in even the most demanding listening scenarios.

Further enhancing its luxury appeal, the Mark Levinson No. 33H is finished in a striking chassis, crafted from high-quality materials that convey elegance and sophistication. An intuitive control interface allows users easy access to various features and settings, making the listening experience both enjoyable and customizable.

With its impeccable build quality, cutting-edge technologies, and commitment to achieving sonic excellence, the Mark Levinson No. 33H stands as a testament to the brand's legacy in high-fidelity audio. Whether in a home theater setup or a dedicated listening room, the No. 33H delivers a performance that is nothing short of extraordinary, making it a worthy investment for any serious audiophile.
