The Pro-Ject Phono Box S2 Ultra is like no other phono stage available today. Punching well above its weight for sound quality, it replaces the popular Phono Box DS and DS+ models in the Pro-Ject range, and still manages to boast an array of features for easy pairing with any modern cartridge.

Pro-Ject’s Phono Box S2 Ultra utilises a fully discrete electronic layout without the use of operational amplifiers (op-amps). Op-amps are commonly used in phono stages to increase the quiet sound from a pick-up cartridge to a level that modern amplifiers can use. However, by shifting away from that technology, Pro-Ject are able to produce a device with a warm, harmonious sound. In addition, the use of polystyrene capacitors makes Pro-Ject’s Phono Box S2 Ultra almost unique on the market, as such components are normally reserved for far more expensive products. Elsewhere, the split RIAA equalisation circuit enables pin-point accuracy of the RIAA curve and the introduction of a subsonic filter ensures your music sounds right in any environment.

The Pro-Ject Phono Box S2 Ultra delivers a true audiophile sound performance that belies its small form and attractive price. With a sonic signature that delivers the full beauty of a vinyl record, it also remains easy to set up. With a series of dip-switches on the bottom of the solid metal casework, there are multiple settings for impedance (MC), capacitance (MM) and gain – so any modern Moving Magnet or Moving Coil cartridge is easy to accommodate.
