Pro-Ject Tube Box S2

Tube Box S2 is our very first product to feature a fully discrete 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 the customer many options to pick from and alter the sound signature to their preference. Tube Box S2 will give a full and relaxed laid back sound with lush mids, just like you would expect it from a much bigger high end tube phono pre-amplifier. 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 MC cartridge, and a 47k ohm input impedance setting is fixed and suited for Moving Magnet and high output Moving Coil designs. The new S2 series aluminum/metal casing protects against vibrations and electromagnetic interference for superior sound. A true high end solution in a much smaller package!
