Wojciech Pacuła has posted a review of the Review: C.E.C. DA53N USB DAC and headphone amplifier (~€1250) at High Fidelity. His conclusions:
Returning to well recorded material with only a handful of instruments showed, that the CEC handles that best. It will be good with rock and similar music, better than with comparable players for the money (with a transport, additional power cord and digital cable it will come at around 10000zl). But with this music the DAC will fully show its assets: good tonal balance, very good resolution, for the money, and juiciness of sound. But we could also hear, that the sound is a tad boosted, but it all will combine into a lively, dynamic and very smooth transmission. In comparison with expensive digital sources, it will be heard, that the sound is slightly simplified, that Mobley’s sax is a bit more “plastic”, but we will not have a “rejection phase”. The CEC fits easily in many different hardware configurations, and should disappoint nobody. This is not hi-end, but for a really reasonable price, we get a classy, “material” sound.
