Pro-Ject has spent decades making vinyl sound better, not just for audiophiles with unlimited budgets. The Phono Box S2 is a compact preamp that solves a real problem: getting the most out of your turntable without replacing your entire setup. It works with both moving magnet and moving coil cartridges, which means it adapts to whatever cartridge you own or plan to upgrade to later.

The real story here is the adjustable gain and loading. Four gain levels let you match the output of nearly any cartridge, from low-output MCs to hot MM models. Switchable input impedance and capacitance give you fine control over the sound signature. In practice, this means you can dial in a precise, noise-free signal without hiss or dullness. The low-noise circuitry keeps the background black, so details like cymbal decay and vocal texture come through clearly. At 45 RPM support, it handles 12-inch singles without a hitch.

The build is solid and the included power supply is clean. One honest note: the S2 is small, so it can feel a bit cramped if you have thick cables. But for the price, this level of adjustability and quiet performance is rare. It’s a smart upgrade for anyone who wants their records to sound alive without chasing boutique gear.
