The Ultra S2 is unusual at this price point in having a discrete op-ampless circuit design along with a full metal casing that protects against interference to deliver a rather special performance.

Project are offering a fully discrete, OpAmp less design that has enabled them to achieve an incredibly harmonuous sound. On top of leaving out operational amplifiers they have decided to use polystyrene capacitors, which significantly contribute to the high end sound of the Phono Box S2 Ultra.

These capacitors have achieved the staus of "Holy Grail" for many audiophiles when implemented in 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 particularly at this price point.
