Description
The Pro-Ject Tube Box DS3 B is an audiophile-grade tube phono equalizer with a balanced architecture, designed for those looking for a warm, rich sound with a characteristic analog charm.
Equipped with two ECC83 tubes, it gives your music depth, volume and a soft nuanced delivery that is difficult to achieve in transistor solutions.
The model supports both MM and MC cartridges, with a wide range of load, gain and capacitance settings - everything is easily changed on the front panel without screwdrivers. The Tube Box DS3 B is also equipped with fully balanced inputs and outputs (XLR), which is ideal for turntables and amplifiers with a balanced circuit - for example, the X1 B or X8 series.
The housing is made of aluminum and steel to protect against electromagnetic interference. This is a phono equalizer that does not just transmit sound - it shapes the atmosphere. The ideal choice for those who want to squeeze the maximum emotion out of vinyl.
