ProJect Tube Box E Phono Pre-amplifier in Black - BLACK FRIDAY SALE

Introducing the new Tube Box S2 Phono Pre-Amp in Black and its on Sale Now

Innovative, miniature sized phono preamplifier with tube output and now with a Black Friday Saving of $190!

Tube Box E finally enriches the E-line with highly popular tube phono preamplifiers featuring 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 giving you many options to pick from and alter the sound signature to your preference.

ProJect Audio Systems Tube Box E will give a full and relaxed laid back sound with lush mids, just like you would expect from a much bigger high-end tube phono preamplifier.

Precise Loading for MM & MC

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.
