Since its founding in 1972, “Mark Levinson” has been recognized by the market as a synonym for high-end audio due to its astounding sound performance and unparalleled luxury of circuit elements and circuit configurations. . Mark Levinson’s sound philosophy is to “reproduce the excitement of live performances by faithfully reproducing the original sound”. We have recently developed the ML-50 monaural power amplifier.
Please enjoy the finest music experience with the monaural power amplifier “ML-50” that embodies the past 50 years and the future of the “Mark Levinson” brand.

【Product details】
In developing this product, the Mark Levinson team looked back on the design and engineering of past monaural power amplifiers that were touted as so-called “signature machines.” All of them are product groups that have had a great influence on subsequent products. The name “ML-50” comes from the “ML-2”, the first power amplifier manufactured from 1977 to 1986. In addition, the large front pannel handle of this product was inspired by the “No20” manufactured from 1986 to 1995 and its upgraded models “No20.5” and “No20.6”. The No.33 (1994-2003) and No.33H (1997-2007) power amplifiers, the brand’s first to bear the “Reference” name, are equipped with anti-vibration isolation feet that provide a solid foundation for the “ML-50.” The concept of the glass front panel and red backlit logo design was taken from the “No53” manufactured from 2008 to 2019. And the “No536” (2015-) power amplifier is the platform for the audio performance of this product.

While using the current top-of-the-line monaural power amplifier “No536” as a platform, the power supply and audio circuitry have been greatly enhanced.
 The noise floor is reduced by increasing the capacity of the high-voltage power supply (voltage gain and pre-driver circuit) capacitors to 13,200uF. Next, we maximized the capacity of the main high-current power supply to 206,800uF and reconfigured the Schottky rectifier for a low-impedance path from the transformer to the filter capacitor for increased dynamic power. Furthermore, distortion is reduced by increasing the bias of the output stage, ensuring an output of up to 20W in the class A area with an 8Ω load, and a record high output of 425W in the class AB area with an 8Ω load. increase. ■Original pure pass circuit design
Following the “Mark Levinson” traditional pure pass circuit design. Low distortion and high transient capability are achieved through the use of carefully selected fully discrete components in a fully balanced circuit configuration for precise electrical transmission from signal entry to exit.

■ Anti-vibration isolation feet
Equipped with anti-vibration isolation feet that dampen vibrations in all four corners of the main chassis. In addition to eliminating unnecessary vibration from the main unit, by lifting the main unit from the installation surface, the left and right external heat sinks enhance convection cooling. Provides better audio performance and stable operating environment.
