Pro-ject Phono Box RS - Vorverstärker

High end phono preamp

High-end phono preamp with unique impedance matching

Lowest noise and the lowest possible distortion make this phono preamp for real vinyl lovers something outstanding.

Not only the breathtaking performance, but also the optimal adaptability to each pickup, through the infinitely variable during the playback adjustable impedance make this precursor to a real highlight. Thanks to the best components, such as the Analog Devices SSM2019 input stages and the Linear Technology LT1010 high-current buffer stage, the Phono Box RS impresses with fantastic top marks for low noise and distortion-free features. Extremely low output impedance makes the Phono Box RS less sensitive to cable selection and lengths. You can choose between purely passive RIAA and DECCA equalization.

The fully balanced design guarantees superior sound quality via the XLR and RCA inputs and outputs. Never before have you been able to enjoy their precious vinyl treasures in such a clear, dry and detailed manner as with the Phono Box RS!
