The McIntosh MA352 expands the Hybrid Drive concept with a vacuum-tube preamplifier and a higher-output solid-state power stage. Four exposed small-signal tubes shape the preamplifier section, while the direct-coupled amplifier delivers 200 watts per channel into 8 ohms or 320 watts per channel into 4 ohms.
Six analog inputs include balanced, unbalanced, moving-coil phono, and moving-magnet phono connections. A five-band analog equalizer, balanced and unbalanced preamplifier outputs, and a subwoofer output allow the MA352 to serve as the center of a more expansive analog system.
