Pro-Ject Phono Box S2 | Phono Preamp

Phono Box S2 is Classic Pro-Ject Design, Upgraded and Refined Audiophile performance with high-grade amplifications modules and WIMA capacitors Dual mono for maximum noise isolation Precise RIAA equalization Handmade in Europe Elevating the Fundamentals Phono Box S2 is the successor to the world-famous Phono Box S, which offered unrivalled sonics and versatility at a price that was unheard-of. S2 is a refinement on that model with an upgraded chassis & circuitry to deliver more micro-detail, improved dynamic-handling, heightened clarity with a soundstage usually found in much more expensive products. Phono Box S2’s housing is an aluminum/steel sandwich construction that is not just sleek aesthetically, but also shields the circuitry from potentially harmful electromagnetic interference and vibration. The bottom DIP panel allows for fine-tuning of electrical parameters with nearly any MM or MC cartridge available.
