Phono Box S was a product favorite, as it offered unrivalled sonics and versatility at a very affordable price. When Pro-Ject created the Phono Box S2, its successor, it had to have exactly that but improve on sound even further.

Phono Box S2 features incredible micro-details, dynamics, and precision with a soundstage usually found in much more expensive products.

The new S2 style housing is made of an aluminum / metal sandwich construction, and not only offers the highest aesthetics but also outstandingly protects it from unwanted electromagnetic interferences and vibrations. This guarantees for an undisturbed listening experience without worries.

The switches on the bottom of the unit allow fine tuning the sound to your preferences and adjusting Phono Box S2 to any available cartridge!

Phono Box S was considered the best option of all entry-level phono stages by many acclaimed hifi magazines, Phono Box S2 is sure to follow its predecessor‘s footsteps and will set new standards at this price point!
