Manley Laboratories, since the late 1980s, has produced tube-based source components, amplifiers, preamplifiers, and professional audio products have retained a remarkably consistent presence in their respective markets. Proudly built in Chino (California), not China, Manley does all their own design, R&D, assembly, and testing in house.
Manley acquired the Langevin brand several years ago, and sells Class-A solid state products under that name.
Notable Manley Labroratories products include:
Manley Stingray iTube, a stereo integrated amp with a built in iPod dock. It's rated at 32 watts per channel, and has a claimed frequency response of 15 Hz to 58 kHz. Also notable are the Manley Neo-Classic 250 and 500 watt monoblocks.
