Full digital equipment - more is not possible at this price!

The Pro-Ject DAC Box S2+ is a D/A converter that performs well above its price range. Namely in terms of sound AND equipment. It offers asynchronous USB transmission up to 32Bit/768kHz and dsd up to DSD256, five selectable filter characteristics, an optical and a coaxial digital input, an external power supply, the great ESS Saber ESS9038 chip - and it's Roon Tested. To ask?

But as always, the proof of the pudding is in the eating – so off to a Pro-Ject specialist retailer.

Technology for good sound:

The solid, brushed aluminum housing, available in silver or black, protects against electromagnetic interference and vibrations (microphonics).
