This is not your everyday device! Period. Well, exclamation mark, really. It is not a streamer but a DAC with an integrated 50W amplifier with a tube driven preamp. It has an USB to connect to a computer and an assortment of digital inputs for other digital devices. Add to that 2 analogue inputs and you have a centrepiece for your audio system.
Now to the digital inputs. The Decco supports the Sonos system in a queer way. Not by interfacing to the proprietary Sonos network, nor by responding specifically to the Sonos remote. No, no. It has a cavity in the back where you can slide in the unpowered Sonos ZP80 and connect it by coax. Out of sight – out of mind, they seem to have been thinking. That’s a new one.
