Pro-Ject Tube Box E Phonostage - Black

Innovative miniature sized phono preamplifier with tube output!
Tube Box E finally enrichens our E-line with our highly popular tube phono preamplifiers.
It features a fully discrete circuit design without using any operational amplifiers (OpAmps). This results not only in fantastic low noise phono amplification with clean measurements and accurate RIAA equalisation, but also ensures a long product life-cycle as maintenance, service and repair are ensured for years and years to come.
It also comes with replaceable tubes for tube rolling and sound-shaping. This gives the customer many options to pick from and alter the sound signature to his preference.
Tube Box E will give a full and relaxed laid back sound with lush mids, just like you would expect it from a much bigger high-end tube phono preamplifier.
It offers support for both MM and MC cartridges and comes with many gain settings to be switched on the front panel. Wide ranging loading options can be adjusted on the bottom of the unit allowing you to precision match your Tube Box E to your cartridge!
The enclosure is fully made out of metal to protect it effectively against electromagnetic interference and vibrations, which can cause unpleasant listening experiences. The front panel and control elements are made out of beautifully machined aluminium.
