Innovative miniature phono preamplifier with tube output!

The Pro-Ject Tube Box E features a fully discrete circuit design without operational amplifiers. This not only results in fantastic low-noise phono amplification with clean measurements and precise RIAA equalisation, but also ensures a long product life, as maintenance, service and repairs are guaranteed for many years. It also features interchangeable tubes for tube rolling and sound shaping. This offers customers numerous options for changing the sound signature to suit their preferences. The Pro-Ject Tube Box E delivers a full and relaxed sound with rich midrange, just as you would expect from a much larger high-end tube phono preamplifier.

Precise adjustment for MM & MC
It supports both MM and MC cartridges and has numerous gain settings that can be switched via the front panel. Extensive adjustment options can be set on the bottom of the unit, allowing you to precisely tune your Tube Box E to your cartridge! The housing is made entirely of metal, providing effective protection against electromagnetic interference and vibrations that can lead to unpleasant listening experiences. The front panel and controls are made of high-quality milled aluminium.
