Pint-sized audio precision

Use this little gem for high-fidelity sound with your digital audio sources, including high-res audio tracks. The Pro-Ject Pre Box S2 Digital measures barely over four inches wide, but it's big on flexibility. Use its stereo RCA outputs to feed pristine audio signals to a pair of powered desktop speakers or a power amp. Or connect your favorite set of headphones to the front-panel 1/4" jack.

Built to impress

The Pre Box S2 Digital sports a dual mono configuration, with two high-performance DACs (digital-to-analog converters) onboard. It can play just about any high-res audio track you send its way, including super-high-res DSD files. There's built-in hardware support for MQA (Master Quality Authenticated) files, such as those available through TIDAL's streaming audio service. Jitter — digital timing errors that can smear musical details — is reduced to vanishingly low levels. It all adds up to surprisingly robust sound, given the Pre Box S2's small size and reasonable price tag.

Praise for the Pro-Ject Pre Box S2 Digital from The Absolute Sound

"The Pro-Ject Pre Box S2 Digital offers audiophiles a very high-value DAC/digital preamp at an almost ridiculously low price. Not only does it include a plethora of important features, but it sounds good, has an elegantly designed control surface, and is expandable."
