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. 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 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.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.

The ML3 is a single-ended (SE) tube amplifier utilizing a very powerful direct-heated triode GM-70 (125W plate dissipation) and a separate power supply. Combining the most sophisticated technologies and electronic design with graceful looks reminiscent of the classic era of tubes, the ML3 is our top-of-the-line, no-compromise product.It is a 32-watt amplifier that operates in pure class A and utilizes no overall feedback. The topology is absolutely unique and incorporates one of the most advanced power supplies ever featured in an audio device. These factors, along with the designer’s unique vision and understanding of the underlying principles of audio electronics, make the ML3 an amplifier without peer.With the ML3 as the centerpiece of a high-end system, the recorded event is recreated in one’s listening room with astonishing verisimilitude. The listener is able to experience an ephemeral yet tangible connection to the essence of the music. These are not empty claims. Those who have listened to the ML3 firsthand have unanimously acknowledged this phenomenon and have reported it to be utterly unique in their collective experience.SE tube amplifiers, in general, have the potential to reproduce music with greater realism than any other amplifier type or topology. The reality, however, is another thing because of the limitations inherent in most designs. These amplifiers can sound lovely in the midrange but their low and high frequency reproduction leaves much to be desired. The ML3 overcomes these obvious limitations. The resultant sound is strikingly similar to the live event.
Along with the ML2.1, the ML3 is practically the only SE tube amplifier available capable of reproducing an entire range of audio frequencies – not just the exquisite midrange but also the most natural and extended bass and high frequencies. The amplifier’s innovative circuitry enables it to recreate the original spectral balance and harmonic structure of the recorded material without losing even the tiniest details and nuances. Due to its extraordinary transparency, the ML3 is also unmatched its ability to recreate a three-dimensional soundstage without boundaries and limitations. As with the ML2.1, the ML3 brings out the most natural sound performance inherent in the signal and unequivocally demonstrates what a properly designed single-ended amplifier can do.
