Pro-Ject head box S2

A high-end headphone microamplifier and an absolute audiophile bargain. This is how its creators define the Pro-Ject Head Box S2, exquisite electronics designed to redefine the sound quality of listening in the intimacy provided by devices such as personal computers or smartphones, both products for which sound quality has always been secondary, as their audio sections lack sufficient power to fully exploit the possibilities of the latest generation of headphones. Equipped with two headphone jacks (which can be used simultaneously) and an RCA input, it delivers 725 mW of power, allowing very high sound pressure levels to be achieved with all types of headphones, combined with outstanding dynamics and transparency. As is the norm at Pro-Ject, the Head Box S2 features high-quality components selected for their sonic qualities inside, plus, also as usual for the Austrian firm, an all-metal construction that provides both aesthetic appeal and robust protection against all kinds of mechanical vibrations and electromagnetic interference.
