Elegant Design Meets Practical Engineering

The Tube Box E brings classic tube warmth to your turntable setup in a sleek, miniature form. Its all-metal enclosure shields against unwanted interference, while the finely machined aluminium front panel adds a touch of sophistication. Available in silver or black, it blends seamlessly into any hi-fi system.

Pure Analogue Performance, Made Simple

Inside, a fully discrete circuit design avoids operational amplifiers (OpAmps), resulting in ultra-low noise and accurate RIAA equalisation. This means your records sound clearer and more natural, with lush mids and a relaxed tonal character. Dual mono circuitry enhances channel separation, delivering a more immersive stereo image.

Flexible Features for Vinyl Enthusiasts

Supporting both MM and MC cartridges, the Tube Box E offers front panel gain control and a subsonic filter to reduce rumble. Loading options are easily adjustable underneath, allowing precise matching to your cartridge. Replaceable ECC83 tubes invite sound-shaping through tube rolling, giving you control over your audio signature.
