The MA352 Integrated Amplifier is a hybrid design that combines the finest of vacuum tube and solid state audio design principles. The result is an eye-catching amplifier that enjoys the best of these two opposing audio philosophies all while reproducing music at the highest quality level.
An all analog design, the MA352 has a vacuum tube preamplifier section that is powered by a pair of 12AX7A and a pair of 12AT7 vacuum tubes; its output stage is a direct coupled solid state amplifier that outputs 200 Watts per channel into 8 Ohm speakers or 320 Watts per channel into 4 Ohm speakers – enough power to properly drive virtually any set of loudspeakers. Dual scale blue Watt meters give an accurate readout of power output for both speaker impedances.
The MA352 has 2 balanced and 3 unbalanced inputs plus 1 Moving Magnet phono input with adjustable loading for connecting a turntable. It has gold-plated speaker binding posts to help prevent corrosion and ensure a quality signal is sent over your speaker cables to your speakers. A stereo preamplifier output is available for connecting a higher-powered amplifier; it can also be used to connect 1 or 2 powered subwoofers for added low frequency performance.
