Original owner - purchased new from Blue Moon Audio in November 2015. Everything you need to know about the Mojo is here: http://www.chordelectronics.co.uk/mojo/
I used it with a host of IEMs and a pair of on-ears; all were enjoyable set-ups. The best value I found was using it with Xiaomi Hybrid IEMs and their Mii on-ears.
It's very good as a main system DAC, too. This turned into the Mojo's primary use in my house as I appreciated its soundstage and voice presentation over other DACs.
The pictures depict a small knick on the corner of the enclosure just above the optical input. It's approximately 0.010" x 0.020" in size. It's very small and hard to notice. I'm rating an 8/10 accordingly. Otherwise the Mojo is in like-new shape.
