Pro-Ject - Tube Box S2

Tube Box S2 is our 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 the customer many options
to pick from and alter the sound signature to his 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 is adapted to
our DS2 line in looks and protects against vibrations and
electromagnetic interferences for superior sound. A true
high end solution in a much smaller package!
