Pro-ject Phono Box RS

Pro-Ject Audio Phono Box RS  "Perfect Condition"
I am the original owner and purchased it June 2020.
Reference class phono preamplifier with unique impedence control. 
The Phono Box RS is an ultra low noise and distortion phono preamplifier for the analog audio purist. Proper impedence matching is key to great sound and the Phono Box RS provides the ability to continuously vary impedence from 10 ohms to 1200 ohms, EVEN DURING PLAYBACK! My favorite feature and why I chose this preamp.
Fully passive RIAA and Decca equalization is selectable. The Phono Box RS offers fully balanced circuitry and both XLR and RCA inputs and outputs. 
Try finding another phono preamp with all these features at this price point!
