Esoteric Tube Amplifier
At a press conference on the first day of CES, TEAC Esoteric launched a new range of source components. That was expected. But what was not expected was Esoteric's manager of overseas sales, Kazutaka Tsuda (above), introducing a new monoblock tube amplifier, the AT-100. Using KT88s in its output stage, the 50Wpc Esoteric amp features a new variable bias system and an output transformer using specially treated copper foil as the secondary winding to give the best coupling from the primary. The heaters of the input and driver tubes are DC-powered, to give the lowest noise; in fact, Esoteric claims the AT-100 is extremely quiet, despite its all-tube design. While it was designed as a power amplifier, a rear-panel switch, in conjunction with a volume control knob on its front panel, turns the AT-100 into an integrated, with three RCA inputs ands one XLR. Price will be $18,500.
