Pro-ject Tube Box S2 MM & MC Phono Stage

Widely compatible with MM and MC cartridges
Comes with two replacable ECC83 tubes 
Dual mono circuitry for optimized channel separation

S2-Line

The Tube Box S2 is a premium phono stage for both Moving Magnet (MM) and Moving Coil (MC) cartridges. In order to achieve the best sound possible, it's become Pro-Ject's first product to feature a discrete circuit design without any operational amplifiers (op-amps).

The Tube Box S2 delivers a relaxed audio performance with lush mids in a full and enveloping sound stage, just like far more expensive pure-valve phono stages are capable of. Thanks to the built-in adjustable gain, capacitance, impedance and subsonic filter settings, it's possible to tune the device to perfectly complement almost any modern MM or MC cartridge. It's also possible to tune the sound further, as the Tube Box S2 is Pro-Ject's first ever product designed for the valves to be replacable - allowing for tube rolling or sound shaping. 

The new S2 casing is a big additional asset to the design, as not only does it deliver the highest visual appeal, but it is also sturdy enough to protect the internal circuitry against unwanted interferences and vibrations, which can cause unpleasant listening experiences. The Tube Box S2 also benefits from protective cages around the valves - inspired by the superior Tube Box DS2 design

Inspired by high-end designs but available for a very appealing price, the Tube Box S2 is a real audiophile bargain.
