About the MP3
The Atma-Sphere MP-3 is a high-end preamplifier featuring a fully differential all-tube design. It includes a direct-coupled high current output capable of driving low-impedance balanced lines, making it suitable for a variety of audio setups. Key features include balanced differential design, XLR connectors for phono and auxiliary inputs, regulated high voltage supply, and a precision 23-position stepped volume control. The preamp also features a zero feedback design throughout and balanced differential passive phono equalization. It uses a tube complement of eight 12AT7s, ten 6SN7s, and one 6AS7. The phono stage offers a frequency response of 0.5 Hz to 90 kHz with high RIAA accuracy. The MP-3 is designed to provide exceptional audio quality with its robust construction and precise components.
