Pro-Ject's Tube Box S phono preamplifier is a dual mono design that uses two audiophile-grade ECC83 tubes, which gives an analogue warmth & bass texture that we love!

The connections on the back of the Tube Box S are straight forward & easy to use.

The fun for me begins on the underside of the Tube Box S, not only can you adjust the input gain, impedance & capacitance to match your cartridge perfectly, but you have the ability to experiment with input capacitance. When using MM or high output MC carts (within the recommended input capacitance suggestions for your cartridge) I feel in doing this you obtain more control over the sound stage of your system, pushing it further forward & wider into the room.
