The Tube Box S2 features a completely dedicated circuit design without using any operational amplifiers (OpAmps). It is also the first Pro-Ject product to come with replaceable tubes for tube rolling and sound shaping. This gives the customer many options to choose from and alter the sound signature according to their preferences. Tube Box S2 will deliver a relaxed, full sound with lush mids, just as you would expect from a much larger high-end tube phono pre-amplifier. It offers support for MM and MC cartridges and comes with many gain settings that can be changed on the front panel. Five variable input impedance settings are available to fit any MM cartridge, the 47,000 ohm input impedance setting is fixed and suitable for high performance MC cartridges. The aluminum/metal housing matches the DS2 line in appearance and protects against vibrations and electromagnetic interference for superior sound.
