Product Description & Reviews

Pro-Ject's Tube Box S2 phono preamplifier with a tube output stage offers unrivalled performance and unique flexibility at an incredibly affordable price. It's one of the most economical ways to enjoy the lush sound of vacuum tube phono gear that we know of, and the ultra-compact size means that the Tube Box S can fit almost anywhere. The sonic quality of Tube Box S2 is extremely impressive, offering a big improvement over Pro-Ject's great sounding Phono Box S. It makes a big improvement over the built-in phono stage on many amps and receivers and offers a perfect upgrade for most analog hi-fi systems. Tube Box S2 is Pro-Ject's very first product to feature a fully discreet circuit design without using any operational amplifiers (OpAmps). It also is the first product to come with replaceable tubes for tube rolling and sound-shaping. This gives you many options to pick from and alter the sound signature to your preference. Tube Box S2 provides a full and relaxed laid back sound with lush mids, just like you would expect it from a much bigger high end tube phono preamplifier. It offers support for both MM and MC cartridges and comes with many gain settings to be switched on the front panel. Five variable input impedance settings are available to adjust to any MM cartridge. The 47k ohms input impedance setting is fixed and suited for high output MC cartridges. The aluminum/metal casing is adapted to Pro-Ject's DS2 line in looks and protects against vibrations and electromagnetic interferences for superior sound. This is all-in-all a true high end solution in a small package.

  • Suitable for MM and MC cartridges
  • Fully discreet circuit design without OpAmps
  • Ultra low noise circuitry with FET input stage
  • External power adaptor and multiple internal power supplies
