I bought to improve the Phono Box S to the sound of my rotator (Denon DP-300F) to my AV receiver (Denon AVR-3313). With the sound of the built-in AVR preamplifier I was not happy because the sound was a bit tired and dull. The Phono Box is a noticeable contrast sound enhancement. The fatigue is largely gone and the music dissolved felt fine. Especially with my pickups from Ortofon (2M Red) to Box seems to understand well. Certainly provide some more expensive phono stages, better sound. As an upgrade to a "simple" Dreher with "ordinary" but the pickup box of Pro-Ject's not a bad choice in my opinion. I would buy the Phono Box to give it back.
