If anything get mojo
Not necessarily. The AKJr will deliver very good sound, and there's no real reason to stack and spend for him at this point.
For me, I have no real desire for the Mojo, as it defeats the purpose (to me) of my 120ll and my balanced Moon cable. I like the sound I'm getting. If you go to the For Sale section of HeadFi, there are (or have been) lots of Mojos for sale by people who tried them and decided to move on. Right now the Mojo is the flavor of the month, but things will change again and people will move on to the next greatest thing. That's the nature of this hobby. The trick is to find what you like and then not rush off to the next hot thing.
