Project Tube Box S

Project's Tube Box S is a newly developed phono preamplifier, designed and constructed with a high quality valve output stage to offer a truly superlative sonic performance, complete the level of warmth and richness that one would expect from any analogue-minded product designed by Project. Despite this sonic superiority, the Tube Box S is still moderately priced and rivals similar units in much higher price points. 

This unit is ideal for mid-priced analogue systems and has been designed with the most demanding audiophiles in mind, offering a vast improvement over the smaller Phono Box S model. There are a wide range of setting parameters to match the Tube Box S to practically any high-quality Moving Magnet or Moving Coil phono cartridge on the market today. The components within have been specifically chosen and precisely arranged to ensure that an audiophile-grade performance is met, bringing an outstanding level of fidelity to valuable vinyl collections.

The Tube Box S provides a solid level of pure dynamic prowess, full transparency, textured and liquid bass, detailed resolution of all audible frequencies, and then tempers these qualities with a blanket of true analogue warmth.
