The Pro-Ject Tube Box range brings the uniquely beautiful sound of vinyl and valves together at a great price.

If you’re an enthusiast of analogue audio, most would agree that the sound of vinyl & valves is a match truly made in heaven. There are few unisons which can evoke such a deeply pleasing and emotional performance.

Turntable legends, Pro-Ject, offer a series of superbly priced valve phono pre-amplifiers under their Pro-Ject Tube Box range. It would be churlish not to investigate further!

Vinyl and Valves

There are numerous arguments surrounding valve phono preamps, which are as numerous for those surrounding the benefits of vinyl itself. For those dedicated followers of valves & vinyl though, nothing else will do.

One solid argument for using a valve based front end for your turntable, is that a valve is able to provide very large voltage swings from a single amplification device. Solid state preamps rely on multiple cascading transistors or FET’s to achieve the same result.

One of the single most important components in any vinyl replay system is the phono pre-amp itself. Low distortion and high headroom are vital to ensure optimum reproduction; as a very pleasant side effect, valves even sound great when pushed beyond their design limit

Sold on the idea of a valve phono preamp yet? Thought you might be! The Pro-Ject Tube Box range of valve phono pre-amplifiers offer high quality, warranted performance from a known brand at a price comparable to some dubious Chinese internet specials.
