ProJect Tube Box S3 B Phono Stage

PREMIUM DESIGN WITH EUROPEAN CRAFTSMANSHIP

Crafted in Europe, the Tube Box S3 B features a robust aluminium chassis that protects against interference and vibration. Its sleek, compact form is available in silver or black, making it a stylish addition to any hi-fi system. Front-panel controls offer easy access to key settings, while dual turntable inputs add convenience for vinyl enthusiasts.

BALANCED AUDIO FOR CLEANER PLAYBACK

The B stands for balanced and thats where this phono stage shines. Using a symmetrical signal path via a 5-pin mini XLR input and balanced XLR outputs, it extracts musical detail while cancelling out noise. This design ensures a purer, more dynamic sound, typically found in far more expensive equipment.

FLEXIBLE CARTRIDGE MATCHING MADE SIMPLE

With gain settings from 40dB to 65dB and ultra-low loading options like 50pF and 10 ohms, the Tube Box S3 B adapts to a wide range of MM and MC cartridges. Each input stores its own settings, allowing seamless switching between turntables. Whether you're dealing with high-capacitance cables or fine-tuning your setup, this phono stage offers precision and ease.
