Description
The Pro-Ject Tube Box E Valve Phono Stage is an innovative, miniature-sized phono preamplifier designed to deliver exceptional sound quality for both MM and MC cartridges. It features a fully discrete circuit design without operational amplifiers, ensuring ultra-low noise performance, clean measurements, and precise passive and active RIAA equalisation.
Built with two replaceable ECC83 tubes, it allows for easy tube rolling and sound customization, letting users fine-tune the sonic character to their preferences. Despite its compact form factor, this unit produces a warm, full-bodied sound with rich mids and a laid-back presentation, much like larger, high-end tube phono stages. Its silver or black front panel finish adds a stylish touch to any hi-fi setup.
Advanced Technical Design for Superior Sound
The Tube Box E incorporates dual mono circuitry for optimal channel separation, gold-plated RCA inputs and outputs for maximum conductivity, and polystyrene capacitors in critical signal paths. Its ultra-low noise circuitry, combined with a FET input stage, ensures clarity and precision, while the well-filtered high-voltage anode power supply enhances stability.
This model offers multiple gain settings,40, 43, 50, 53, 60, and 63 dB,allowing precise matching to different cartridges. For further customization, capacitance and impedance settings can be adjusted to ensure perfect compatibility with your specific setup. These engineering refinements result in detailed, distortion-free playback with a noise floor as low as 77 dB at 40 dB gain.
Practical Controls and Cartridge Matching
Designed with convenience in mind, the Tube Box E features front-mounted controls for gain adjustment and a subsonic filter, which operates at 20 Hz with an 18 dB/octave slope to remove unwanted low-frequency rumble. Its wide loading options, accessible from the underside of the unit, make it possible to fine-tune performance for both moving magnet and moving coil cartridges.
This flexibility ensures that vinyl enthusiasts can optimise their listening experience regardless of cartridge type. The robust all-metal enclosure shields sensitive components from electromagnetic interference and vibrations, preserving sound integrity and reducing unwanted noise for a consistently enjoyable listening session.
Built for Longevity and Audiophile Enjoyment
The Pro-Ject Tube Box E Valve Phono Stage is engineered for a long product life, with serviceability and maintainability in mind. The replaceable tube design not only enhances sound-shaping potential but also ensures that the unit can be kept in top condition for years to come. The machined aluminium front panel and solid construction offer durability and aesthetic appeal, while its compact size makes it suitable for any system without compromising on performance.
By combining advanced technology, high-quality components, and classic valve warmth, the Tube Box E stands out as a perfect upgrade for vinyl lovers seeking premium sound in a compact, stylish form.
