The Pro-Ject Tube Box E is ideal for vinyl lovers who want to bring valve warmth and clarity to their system without taking up extra space. Supporting both MM and MC cartridges, it offers front-facing gain control and a subsonic filter for quick adjustments, plus a wide range of loading options on the underside to fine-tune performance to your cartridge.
Its fully discrete design avoids op-amps entirely, resulting in lower noise and cleaner sound. The two ECC83 tubes can be swapped out, letting you shape the tone to your taste. Housed in a sturdy metal case that protects against interference, the Tube Box E delivers a smooth, laid-back sound with excellent detail and separation.
