Following the long-term success of the Tube Box S2 and Tube Box DS2 comes the incredible new Tube Box DS3 B True Balanced phono preamp.
The Tube Box DS3 B features both single-ended RCA and Balanced XLR inputs along with single-ended RCA and Balanced XLR outputs. For best results, connect a moving coil cartridge via the Balanced XLR input and then connect the Balanced XLR outputs to your Balanced system. The RCA and XLR inputs feature separate memory for setting the impedance, capacitance, gain and subsonic filter.
Both outputs are always active, so you could even run a local system via the RCA outputs, then run long XLR cables to a remote system. This is a perfect solution for distributed audio systems when you want the turntable in a convenient location.
The best part is that Pro-Ject still thinks value is an important element to consider when designing a new product. The Tube Box DS3 B retails for just $1,099, so another class-leading performer! Order for delivery soon!
