Tube phono preamp

Innovative miniature tube preamplifier with valve output and high-quality sound! Discrete component circuit design without the use of operational amplifiers (OpAmps). Equipped with replaceable tubes for tube rolling and sound shaping. This offers the customer many options to choose and modify the sound signature according to their preferences. The Tube Box S2 will provide a full and relaxed sound with lush mids, just as you would expect from a high-end tube phono preamp. It supports both MM and MC cartridges and comes with many gain settings that can be switched on the front panel. There are five variable input impedance settings to suit any MM cartridge, with a fixed 47 kOhm input impedance setting for high-gain MC cartridges. The aluminum/metal case protects from vibrations and electromagnetic interference for superior sound quality.

It receives many praises for its warm, detailed, and engaging sound quality. Users also praise the precise channel separation and lack of background noise, which contribute to an immersive listening experience.
