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.

What is a Phono Stage?
A phono stage takes the low-level electrical signal, generated by the pick-up cartridge on your turntable, and amplifies it to LINE level. When it's at LINE level, you can connect the outputs of your phono stage to any LINE or AUX input on your amplifier. If you do not have a phono stage, when you connect the turntable to your amplifier the signal will be very quiet, and if you turn it up to normal listening level it will sound distorted and noisy.
You do not need an external phono stage if...
In both of these cases, the built-in phono stage needs to support your pick-up cartridge (see below).
Do I need a specific type of Phono Stage?
Yes. You need to buy a phono stage that suits your particular type of cartridge. If you have a Moving Magnet (MM) cartridge, you need an MM-compatible phono stage. If you have a Moving Coil (MC) cartridge, you need an MC-compatible phono stage. This is due to the different output levels of MM and MC cartridges (as MC cartridges are so quiet, they require more Gain).
What do all of the Setting adjustments mean?
Cartridges are complex micro-mechanical devices, and the way a phono stage treats the electrical signal they generate can dramatically impact the end sound quality. When setting adjustments are available, the one adjustment you always need to check, regardless of the cartridge, is Gain. The level of Gain directly affects all cartridges, as the ultimate task of a phono stage is to amplify the electrical signal.
After Gain, the type of Settings you need to adjust are dependent on the cartridge used...
Some phono stages have other Settings available, which are not cartridge dependent. For example...
