Further to my last, if you're not interested in gaming at all, then the IFI Zen DAC gets fantastic reviews (it's £130 here in the UK). It'll future proof you for the headphones to come. But if gaming is a consideration, and you want to be able to use a mic, then the G6.Ok since the g6 is almost at the same price as e10k,is this a no-brainer? I've heard that g6 is basically just as good as fiio k5 which is out of my range.
For gaming the X2 also works fantastically with the V-Moda Boompro Microphone, it's like they were made for one another.
Sorry to keep mentioning gaming, but I don't know what it is you're focusing on overall, so I'm thinking of the potential bigger picture.
