You know, I just let a Mojo unit slip by me for $600 AUD yesterday, reason being I may have an upcoming IEM purchase soon.
What cable are you running with your Mojo / 1Plus2?
And tell me more about this sound difference you hear, every juicy detail.
Mojo just has a very natural signature would be the way I would describe it, the DAC and Amp adding or taking away little from the music. It just flows. DX90 pairs beautifully and the cable was made up by a chap on the Mojo forum, der gabe. Took a while arriving but its a short, 75ohm co-ax. Its re-assurance that the cable is not losing anything, but the DX90 driving Mojo through a regular short stereo analogue cable also works well!
My 1Plus2s are still on loan, can you identify from the cable, exactly which one and generation it is? I've tried reading through this thread, I'm about a third way through after a month!
