ML2 is the first in a line of LAMM single-ended amplifiers with a regulated power supply that represent a new generation of power amplifiers employing unique high current low impedance power vacuum tube triodes (6C33C) in both the output stage and voltage regulator. Implementation of these triodes has allowed to create an output transformer with a very low turns ratio and, as a consequence, extended (as compared even to the most advanced modern vacuum tube amplifiers) frequency decade factor, as well as dramatically reduced leakage inductance.
Chosen by the Design and Engineering Committee as one of the most innovative products of the year in the “specialty audio” category, the ML2 is a first single-ended amplifier on the market capable of reproducing a full range of audio frequencies and recreating the original spectral balance and harmonic structure of the recorded material with almost 100% accuracy. Another unique aspect of the design enables the ML2 to recreate a three-dimensional soundstage without boundaries and limitations while maintaining the extraordinary transparency of perceived sound.
A custom-designed output transformer, along with a unique output stage and high-current regulated power supply, allow the ML2 to drive most of the real world speakers and yield tremendous sonic stability under most dynamic conditions. Although the ML2s can drive most speakers, their full potential is realized in tandem with high efficiency speakers (94 dB and higher).
Two multi-turn trimming potentiometers accessible through special openings in the amplifier’s chassis, along with two sets of test points, allow the user to adjust and measure the nominal value of plate voltage and plate current of the output tube by using an external voltmeter.
In conceiving and executing an overall design of the ML2, the goal was to utilize the modern technology and processes while recreating a look reminiscent of the long-gone genuine vacuum tube era. Each amplifier is carefully constructed and handcrafted of the finest materials and world class parts, some of which include military graded low noise DALE metal film resistors; ELECTROCUBE and ROEDERSTEIN film capacitors; high frequency switching grade CORNELL DUBILIER and UNITED CHEMI-CON electrolytic capacitors; HAMMOND chokes; gold-plated NEUTRIC XLR connectors; and military graded low noise long life vacuum tubes. Special attention was given to designing the toroidal power transformer, which has no mechanical contact with either the transformer cover or the chassis, and is suspended in a special encapsulant which almost completely absorbs even the residual mechanical vibrations. This plays a significant role in assuring the absolutely unique clarity and micro-resolution during sound reproduction.
The ML2 works on all world AC line voltages without elaborate modification.
