Me too, doing the same. Althought with added Audeze's LCD2 and AKG Q701 which both, btw sound excellent. What are you using for connection from Mojo to iTube? Me, personally, optical input (VdH Optocoupler), audioquest 3,5mm - RCA adapter and XLO - iTube - DiMarzio to iCan. I hear the difference, clearly... However, some recordings sound the same or even better directly from Mojo.
