Tube Box DS3 B

Dual-mono balanced tube phono preamplifier

Immerse yourself in the world of high-end tube sound with the new Tube Box DS3 B – an addition to our renowned product portfolio designed for audiophile enthusiasts. The Tube Box DS3 B combines exquisite craftsmanship, premium materials, and technical innovations to offer you an unparalleled listening experience.

Cartridge Adjustment Options: The Tube Box DS3 B allows you to connect two turntables simultaneously and offers the flexibility to adjust your settings directly on the front panel. With gain options from 40dB to 65dB, you can achieve the perfect match for a wide variety of cartridges and seamlessly integrate them into your hi-fi system. The continuously variable load impedance adjustment via a potentiometer allows you to adjust the impedance during playback and instantly assess the effect.

Symmetrical signal transmission: Thanks to balanced inputs and outputs, the Tube Box DS3 B offers a pure signal path. Connect your turntable using either the 5-pin mini-XLR cable or standard XLR cables and enjoy interference-free transmission of musical information. The selection of high-quality components, including E88CC vacuum tubes and polypropylene capacitors, guarantees stunning sound quality.

E88CC vacuum tubes: The E88CC tubes used in the Tube Box DS3 B operate with low noise and microphonics, producing detailed bass with warm treble. Immerse yourself in a world of sonic purity and precision.

Continuous impedance adjustment: The stepless adjustment of the load impedance allows for continuous adaptation during playback. Find the optimal load impedance for your cartridge and experience music in its purest form.

High-quality materials and manufacturing: The Tube Box DS3 B is carefully designed and manufactured in Europe, using high-quality materials to ensure a long service life and excellent performance.
