"Unrivaled sonics and versatility at a very affordable price. 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 aluminium/metal sandwich construction and not only offers highest aesthetics but also 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." - Pro-Ject
