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 replaceable – 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.
