The DXC390 supports the Optical, Coaxial (digital connections) and the RCA analog connection output. If the Sonos device has one of those as an Input connection, then you can connect the player to the Sonos device.
Thank you

Bottom of the unit is flat but there is a vent on the bottom as well that you don't want to cover. So it wouldn't be recommended to have this flush to the cabinet.
Thank you
