Pro-Ject Tube Box DS3 B True Balanced Phono Preamplifier

The Pro-Ject Tube Box DS3 B is the latest addition to our Tube Box range, which has been an integral part of our product portfolio for many years. This precision tube phono amplifier features balanced inputs and outputs and benefits from unique circuit technology developed by Dr. Sykora, combined with ultimate components.
With the possibility of connecting two turntables at the same time and easy setting on the front panel, you can store settings for each input in memory. Gain ranges from 40dB up to 65dB make it possible to precisely match different cartridges and integrate it seamlessly into your HiFi system. The load impedance is continuously adjustable via potentiometer, a unique feature from Pro-Ject Audio Systems that allows you to adjust the impedance during playback and assess the effect of different settings.
