I am using a LG V10 now with a fiio E11k and fiio ex1, would I have anything to gain from a fiio E12a?

I use a E11K at the moment for my ex1 and v-moda M80, I would like a bit more power hence the E12 or the E12A. the power on the E11K is the job with enough power to spare but it doesn't look flush on the back of my MI Note, so I wanna buy a new amp. Thanks in advance, all comments appreciated.
