Dual-mono balanced tube-phono preamplifier
Made in Europe

HIGH-END TUBE SOUND
The Tube Boxes have been an integral part of our product portfolio for many years. Now the new Tube Box DS3 B adds balanced inputs and outputs to the popular tube amplification.

BALANCED SIGNAL TRANSMISSION
Connect your turntable with either the 5-pin mini XLR cable or standard XLR cables and benefit from the balanced signal path. Balanced transmissions consist of a hot and a cold signal. Both signals effectively carry the same musical information. The Tube Box DS3 B can now extract the final musical information and remove any noise that may have been added during transmission. All components used, such as tubes and polypropylene capacitors, have been selected according to audiophile standards and guarantee a breathtaking sound experience.

Balanced XLR
Interference-free
A balanced connection can extract the final musical information and effectively filter out all noise.

E88CC
Vacuum tubes
The E88CC tubes are low-noise and low-microphone. Enjoy the detailed bass paired with warm highs.

Setting
Continuous impedance load
The load impedance can be adjusted via a potentiometer. This allows you to continuously adjust the impedance during playback

Made in the EU
High quality materials
The new Tube Box DS3 B is carefully designed and manufactured in Europe.
