Project Phono Box SE II


New Old Stock Clearance, while stocks last

The Project Phono Box SE II is a phono pre-amplifier suitable for both MM (Moving Magnet) and MC (Moving Coil) cartidges. Boasting an extremely high quality construction featuring all metal casework and special low noise circuitry, the Phono Box SE II’s performance is superb.

The updated Phono Box SE MKII features a heavier and thicker metal chassis to prevent contamination from electromagnetic interference and reduce vibration. From the gold plated RCA connections to the dual-mono signal paths, the Phono Box SE II is a compact solid-state phono preamp, with selectable impedance and capacitance for any MM or MC cartridge.  The Phono Box SE II has ultra-quiet backgrounds and an outboard power supply making it quiet enough to have an exceptional signal to noise ratio, making it a great choice for virtually any cartridge. The Phono Box SE II has a warm, powerful sound with excellent extension and performs at a level way beyond its price.
