Product Summary
The Pro-Ject Tube Box S2 is a compact phono stage designed for customers who want the flexibility of MM and MC cartridge support with the extra character of a tube output stage. It is a smart choice for vinyl listeners who want something more expressive and more adjustable than a basic phono preamp.
A big part of the appeal is its fully discrete design and replaceable ECC83 tubes, which give it a more engaging and more tweakable feel than many small phono stages. Pro-Ject has also made it easy to tailor to your cartridge, with front-panel gain adjustment, multiple loading options and a handy subsonic filter. That makes it especially attractive if you want a compact phono stage with proper system-matching flexibility and a fuller, more relaxed presentation.
