Project Pre Box Dac S2 Digital is one of the hottest dacs of 2018. The Pre S2D uses two new top of the line ESS 9038 chips for digital decoding - quite a feat at this price - to provide great performance. The Pre S2D has a handy input/volume screen, is a tiny size in a surprisingly solid housing, includes remote and has 8 built in filters to choose from.
Matches up well with many easier to drive headphones - Audioquest, Klipsch Heritage, Meze 99, Campfire Cascade, Sony, Audio Technica, Focal Clear, Grado, etc. Great way to upgrade the sound from a Sonos Connect or TV (optical in), computer (usb in), or older cd player (Coax in).
Darko.audio review: Overall, Pro-Ject’s S2 Digital a well-judged unit, blending a wide range of useful features, good sound quality and a very attractive price. For the money, it’s a very strong proposition.
headfonics.com: the Pre Box S2 Digital is one of those all-in-one solutions that defines what a typical 2018 digital audiophile might be looking for. Roon Tested, full MQA unfolding, a low noise floor, easily transportable and a very likable tonal presentation with a very modern DAC chip solution inside. This is one well designed, feature-heavy little box.
