Nice review. I would just tweak the description from a "solid state headphone amplifier and a DAC" to (more accurately), a DAC with a variable line out that can drive IEMs and headphones. There is no seperate headphone amplifier as in traditional DAC/amp combinations. The Mojo's analogue stage is very simple and has only the critical I/V conversion. Volume is handled in the DAC. This is the reason there are no analogue inputs. It's transparent to the DAC because of this and a unique device.
