Pro-Ject Tube Box S2

Utilizing a fully discrete signal path, two ECC83 preamp tubes, and a dual mono signal path, Pro-Ject's Tube Box S2 is one of the easiest and cleanest-sounding ways to add some extra analog warmth and grit to your hi-fi listening setup. With a special power supply design, RF-shielded chassis, and low-distortion signal path, the Tube Box S2 provides an uncommonly clean tube listening experience without sacrificing the fullness and warmth one associates with tube preamps.
