The Pro-Ject Tube Box S2 is a unique turntable preamplifier created for music lovers looking for the warm, rich and relaxed sound typical of vacuum tube technology. It is the ideal choice for anyone looking to add a touch of analog magic and musical soul to their Hi-Fi system.

 Its special feature is a completely discrete circuit without operational amplifiers (OpAmp), which ensures exceptional signal purity. The key advantage is definitely the vacuum tubes (electrons), which can also be replaced. This allows the user to actively shape and adapt the sound character of the system to their own preferences by choosing different tubes.

 The Tube Box S2 supports both MM and MC cartridges and boasts a wide range of gain and input impedance/capacitance settings, ensuring optimal matching with each cartridge. An aluminum and metal housing protects the delicate internals from vibration and interference, rounding out a package that offers the sound and features of much more expensive tube preamps.
