Tube Box S3 B
Audiophile tube warmth.
The Tube Box S3 B is a audiophile phono preamplifier that brings true analog warmth to your vinyl playback. It features a fully symmetrical and discrete gain stage, balanced 5-pin mini XLR input, and balanced XLR outputs.
Available in silver or black and made in Europe, the Tube Box S3 B is a compact yet powerful upgrade for any serious vinyl setup.
Cartridge loading options
Large ranges from 40dB up to 65dB are possible. A fully balanced design makes all the difference here. You can perfectly match it with a wide variety of cartridges and integrate it into the rest of your HiFi system, matching the volume levels accurately to other sources like CD players or streaming devices. Ultra low values like 50 pF or 10 ohms allow you to account for special situations, for example sub-ideal higher capacitance cables. Each input settings are stored in the memory.
