Stello is a brand of April Music, a Korean manufacturer of distinctive audio electronics. The distinctiveness is felt not just in the looks, but also in the features: this is just about the only DAC we can think of with an I2S input. Matched – surprise, surprise – by a Stello CD transport, this is in fact an industry-standard interface, but is normally used within equipment (on circuit boards rather than between boxes). Its great advantage over the usual serial interfaces is that it carries clock signals separately from data, which should, in principle, make jitter less of a problem.
