Yeah, that's because of the new major Head-Fi update that changed about anything (I gotta update the link to the new site once I've moved my lazy ass over to my laptop). It should be visible somewhere on my profile under "showcase" (unless it is among the ~70 reviews that seem to have magically disappeared since the update...).
My personal preference clearly tends towards the iBasso due to the more stable output impedance, lesser hiss with sensitive in-ears and less smooth character. Still I'm enjoying my Chord Mojo though. If you ask me which I think is better objectively, I'd say both are in the same league but different in terms of presentation and that it's up to one's personal preference which one to prefer.
Then there's the AMP2 module that sounds a bit smoother than AMP1, however not as smooth/"laid-back" as the Mojo (to my ears).
