PROJECT Tube Box S2 - Approx 3 years old, no longer required as upgraded to high end integrated amp. Original price approx $900.

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 many options to pick from and alter the sound signature to 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 MM cartridge, the 47k ohms input impedance setting is fixed and suited for high output MC cartridges. The aluminium/metal casing protects against vibrations and electromagnetic interferences for superior sound.

A true high end solution in a much smaller package!
