Since introducing their first phono stage in the mid-1990s, Pro-Ject have now sold over 500,000 Phono Box products, cementing their position as a true leader in the analogue hi-fi market. The Phono Box Ultra 500 is a truly special phono stage built to celebrate the momentous milestone. Deceptively small and surprisingly affordable, the Phono Box Ultra 500 is a special edition device made to stand out from the crowd.

Internally, the Phono Box Ultra 500 makes use of the same technologies as the Phono Box S2 Ultra, with its fully discrete layout, polystyrene capacitors and precise RIAA equalisation resulting in a warm, harmonious sound. But where it stands apart is in its striking chassis. The Phono Box Ultra 500’s elegant chrome surface masks a copper chassis, specially chosen for its superior ability to protect against high-frequency interferences.

Easy to set-up with a variety of capacitance, impedance and gain settings, the Phono Box Ultra 500 is easy to partner with any modern pick-up cartridge.

Supplied in a wooden display box and limited to 500 pieces worldwide, the Phono Box Ultra 500 is a true prestige piece that would sit comfortably at home in any premium listening environment.
