Pro-Ject Audio Tube Box DS2 Phono Valve Pre-amplifier

$1,178 $1,309

Unlike conventional phono stages, the Tube Box DS2 harks back to a classic era of analogue sound, using a pair of valves to amplify your turntable’s signal. That different approach gives your sound a remarkably different feel, with outstanding warmth and a lush, laid-back sound that other phono stages just can’t touch.

The Tube Box DS2’s front-panel controls give you push-button control over your sound, allowing you to customise your settings on the fly to get the most out of your records. Whether with a Moving Magnet or Moving Coil cartridge, the Tube Box DS2 delivers rich, natural tones, proving it to be a sophisticated phono stage for the discerning record lover.
