Fully Discrete Pro-Ject Phono Box S2 Ultra MM/MC Phono Preamplifier Has Modest Price But Delivers a Big Sound: Audiophile Construction (Polystyrene Capacitors) Marries with Excellent Versatility
Spin vinyl and experience the stunning dynamics, transparent clarity, and three-dimensional soundstaging a dedicated high-end MM/MC phono preamplifier delivers for less money than you might think with Pro-Ject's Phono Box S2 Ultra. In keeping with company founder Heinz Lichtenegger's decades-long mission to make cutting-edge analog playback accessible to everyone, and using trickle-down technology from the company's limited-edition Phono Box Ultra 500, the component stretches the outer boundaries of the price-performance envelope. For excellent versatility, it includes switchable input impedance/capacitance, six adjustable gain levels, and a switchable subsonic filter.
The keys to Phono Box S2 Ultra's enticing sound begin with its polystyrene capacitors, normally found only in much more expensive high-end phono preamplifiers. The decision to reject cheap operational amplifiers in favor of discrete circuitry results in a remarkably natural character as well as its ability to deliver a dynamic punch that'll keep you viscerally connected to your music. Pro-Ject continues to pull out all the stops by way of innovative split passive/active RIAA equalization – a feature unheard of in an entry-level phono preamplifier. It gives Phono Box S2 Ultra a bottom-end grip and a sweet, upper-register sweetness that'll remind you and your guests that vinyl really does rule.
On the exterior, a thick metal casing protects your music from electromagnetic and radio interference, making Phono Box S2 Ultra a remarkably quiet unit that puts the spotlight where it belongs – on the music. Plus, the compact 4.05 x 1.45 x 4.68-inch footprint makes system setup and positioning a snap. Our 100% Satisfaction Guarantee gives you all the security you need in going the Ultra route.
