The Pro-Ject Tube Box DS is a valve-output phono pre-amplifier that offers improved performance over the original Tube Box S/E II, whilst maintaining an appealing price.

The Tube Box DS presents an impressive sound, making it a great audiophile upgrade for almost any mid-priced analogue hi-fi system. With a high-quality variable impedance dial and a switchable Sub-Sonic Filter, it can meet the needs of almost any MM or MC phono cartridge on the market. The carefully selected audiophile-grade components make it possible to enjoy your valuable vinyl collection like never before.

For cartridge matching, there is an extensive list of settings adjustment available. On top of the usual Gain and Capacitance adjustments, the Tube Box DS boasts a fully adjustable dial for attenuating the Input Impedance. This allows for perfect matching with almost any Moving Coil cartridge on the market, and it can even be adjusted during playback to tailor the sound perfectly to your preference.

The class-leading music reproduction qualities of the Tube Box DS deliver pure dynamics, full transparency, analogue warmth, bass texture, detail resolution and purity across all audible frequencies. All-in, it effectively brings a retro ethic to modern phono electronics.
