Pro-Ject Phono Box S2 Ultra Discrete MM/MC Phono Preamplifier - Pro-Ject

Phono Box S2 Ultra – Luxury and audiophilia combined!
The Phono Box S2 Ultra is like no other phono preamplifier in its segment. The incredible success of our Phono Box Ultra 500, incited us to introduce this marvelously sounding phono preamp into our regular S2 line. The solid metal casing protects against interference and the internal design remains as spectacular as before.

We are offering a fully discrete, OpAmp less design, which enabled us to realize an incredibly harmonious sound. On top of leaving out operational amplifiers we 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.
Compatible upgrade power supply: Accu Box S2.
