MM/MC phono preamplifier - Luxury and audiophilia combined

The Phono Box S2 Ultra is like no other phono preamplifier in its segment. The solid metal casing protects against interference and the internal design remains as spectacular as before.

A fully discrete, OpAmp less design allows the realization of incredibly harmonious sound. On top of leaving out operational amplifiers Pro-Ject decided to use polystyrene capacitors, which significantly contribute to the high end sound of the Phono Box S2 Ultra. These capacitors are known amongst audiophiles as the holy grail for phono preamplifiers. The split RIAA equalization enables a pin-point accurate representation of the RIAA curve, a luxury many other phono preamps do not possess.
