Cary Audio Design PH-301MM is a phono equalizer preamplifier designed for demanding record enthusiasts. The PH-301MM is an all-vacuum tube design utilizing one 12AU7 and two 12AX7 dual triodes. The RIAA equalization curve is derived from a passive RC circuit located between the two gain stages, providing accurate and precise audio reproduction.

The PH-301MM features a separate power supply to ensure extremely quiet operation, and is perfectly matched to any of the high-end Cary integrated amplifiers or pre-amplifiers. With its gleaming chrome-plated chassis and black anodized front plate, the PH-301MM adds a touch of elegance to any audio system.
