Pro-Ject Phono Box S2 Ultra Phono Stage
Pro-Ject Phono Box Ultra S2 Phono Stage is like no other phono preamplifier in its segment. The incredible success of the Phono Box Ultra 500, incited Pro-Ject to introduce this marvelously sounding phono preamp into the regular S2 line. The solid metal casing protects against interference and the internal design remains as spectacular as before.
Features
- Audiophile Performance
- No operational amplifiers used!
- Audiophile-grade polystyrene capacitors
- Precise RIAA equalisation
- Switchable Subsonic filter ā18dB @ 20Hz
- Switchable input impedance/capacitance
- Solid metal casing prevents interference
- Six adjustable gain levels
- Outstanding sound quality
No OpAmp
Pro-Ject are offering a fully discrete, OpAmp less design, which enabled us to realize an incredibly harmonuous sound. On top of this, they 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.
