ML2.2

Monaural Power Single-Ended Tube Amplifier (18 Watts)

A new generation of single-ended power amplifiers

Chosen by the Design and Engineering Committee to receive the Innovations Award at the International Consumer Electronics Show in Las Vegas as the most innovative product of the year in the “specialty audio” category, the original ML2 was 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. The designer’s unique vision and nuanced grasp of audio electronics has created an amplifier capable of capturing the essence of your favorite music like never before.

Design Elements

The ML2.2 single-ended power amplifier is a proud successor in a line of the ML2 series (the original ML2 and its replacement, ML2.1) and represents a new generation of single-ended power amplifiers with regulated power supply employing a unique high current low impedance power vacuum tube triodes 6C33C in both output stage and power supply.

Implementation of these triodes 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.

The ML2.2 proudly continues this tradition. Whereas both – the ML2 and the ML2.1 – were completed products perfectly capable of functioning to the full of their potential without upgrades or modifications, it became the designer’s drive to expand the limits of this topology and introduce some features of the ML3 Signature into the ML2.1 design.

The sonic result is a most seamless fusion of the ML2.1 and ML3 Signature that leaves the listener totally immersed in the music performance as well as pleasantly surprised at the palpable breathing presence of the music material. The ML2.2 is an amplifier that sonically is much closer to the ML3 Signature while pricewise is closer to the ML2.1. The meticulous build quality, high quality of parts and materials along with innovative topology make the ML2.2 a truly prized possession of any music lover.

Components

The output stage with its high-current voltage regulator section grows out of that in the ML2.1 and implements certain changes that relate specifically to the use of most recently introduced parts of higher quality.

In contrast to the output stage, the input stage has been totally redesigned and is based on that of the ML3 Signature amplifier. This innovative front-end topology was incorporated because of specific characteristics of the output tube. It brought about a dramatic step forward in sound quality while keeping the cost within the price category of the ML2.1.

Single-ended tube amplification has the greatest potential of reproducing music with maximum fidelity to live sound. Because of several inherent limitations of the format, most SE tube amplifiers recreate a beautiful midrange but shortchange the low and upper frequencies. The ML2.2 overcomes these limiting factors to reproduce the thrilling sound of live music.

The ML2.2 along with the ML3 Signature are the only single-ended tube amplifiers that reproduce the entire spectrum in the audio frequency range. A midrange to die for supports a superbly natural and extended bass along with exquisite upper frequencies. The amplifier’s innovative circuitry allows one to hear the original spectral balance and harmonic structure of the recorded material without loosing the smallest of detail and nuance.

Another unmatched feature of the ML2.2 is the breathtaking, transparent, three-dimensional soundstage it throws seemingly without boundaries or limitations. The ML2.2 brings you a very natural and engaging sound.

Advanced technical solutions are used in the design of the ML2.2. Custom-made output transformer of very high quality and unique front-end and output stages, plus the sophisticated power supply, free the ML2.2 to drive most real-world-load speakers yielding effortlessly dynamic sound.
