Innovative Audio is one of New York’s leading High End Audio store. Located on Manhattan’s East Side ( 150 East 58th Street) in the A & D Building. Innovative Audio has always been dedicated to providing their clients the best sounding (and performing) audio components available. The Lamm ML 2.1 mono block fits this description very well. Vladimir Lamm, who designs and assembles all of his company's products, emigrated from the Soviet Union in 1987. Before that, he received training in electronics at the university level—during which time he also played percussion in a symphony orchestra—and worked as an engineer for the Soviet military and space programs, as well as for one of Russia's most-well-known producers of consumer electronics. In many ways, the ML2.1 is the culmination of everything Vladimir Lamm has learned about audio amplification throughout his career. It uses a single output tube, the Russian-designed 6C33C, operating in single-ended mode to drive a loudspeaker load with approximately 18W of power. The ML2.1's input stages, which comprise a 12AX7 dual triode for voltage gain and a Russian 6N6P driver tube, are also fully regulated—again, with tubes. Here, a 5651 voltage reference tube creates a reference signal from the input, and a 6AK5 miniature pentode continuously compares the output signal with the reference, and corrects the former as necessary by amplifying the difference. Each ML2.1 has a pair of input jacks: an RCA for unbalanced operation, and an XLR for unbalanced operation. Because balanced operation isn't really an option in an amp of this sort, the input circuitry addressed by the XLR is only quasi-balanced. Lamm says he provides the jacks merely for the convenience of users who have that sort of cable, and not with any claims of improved performance. At the other end, three pairs of binding posts are provided, for operation into loads of 4, 8, and 16 ohms. The rear-mounted power switch addresses a protection circuit that begins by powering all the tube heaters; then, two minutes later, after the caps have charged up and the tubes have warmed up a little, a hefty relay kicks in and the plates see their respective rail voltages. This is a very safe and reliable protocol. A reviewer in one of the leading audio publications said: “To listen to the ML2.1s was to imagine—that's the most certainty anyone can apply to such a thing—that I was hearing music's original complex wave stripped of more garbage than ever before: Notes were more distinct, as were the relationships between them. Sounds were true, and the presence of the performers in my room, though always little more than a suggestion, was surer and more engaging.

Cosmetically they are near mint with only a couple of tiny nicks on the top of the faceplate of one amp. Description: Tubed, monoblock power amplifier.
