We reviewed iBasso's D10 Cobra, a well-featured DAC and headphone amplifier with both USB and S/PDIF inputs, as well as a line input. The D4 Mamba is a very similar device, but lacks the S/PDIF option and comes in a slightly smaller case, 92 millimetres long, instead of 104 millimetres. (The other dimensions being a width of 55 millimetres and a thickness of 21 millimetres).
