Tube Box S2
Phono Valve Pre-amplifierUnlike conventional phono stages, the Tube Box S2 harks back to a classic era of analogue sound, using a pair of valves to amplify your turntable’s signal.
This alternative 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.



A pint-sized performer
With a host of settings, the Pro-Ject Tube Box S2 works with both Moving Coil and Moving Magnet cartridges to make you fall in love with your records all over again.
The Pro-Ject Tube Box S2 offers all this in a compact form-factor that’s small enough to fit in the palm of your hand. Good things truly do come in small packages.
