I wrote that quite awhile ago but still think the Cayin C5 is all that. It's been a couple of years since I owned the Mojo but I do remember that it's lack of a bass boost was a deal breaker for me. I am somewhat of a bass head and love the bass boost on the C5. And really, I thought the IDSD Black Label was better than the Mojo. The Black Label has a bass boost but it is nowhere as good as the C5 to my ears. I actually have 2 C5s in case they go away. That little amp can easily drive my DT880/600. That's some impressive power! The pairing of the C5 with the Denon D600 is magical to me. If you aren't a bass head and listen to music that isn't bass oriented, than perhaps the Mojo would be the best choice. I listen primarily to EDM through headphones so having the bass boost is really important to me.
