Unless I can quickly get rid of my current stuff, I'll do it later this summer. I imagine Chord Mojo would be a nice little buddy for Noble IEMs?
The Mojo is very portable and works great if you're just looking to power IEMs with it. If you can stretch the budget (or want to use full-sized headphones with a full 6.5mm jack as well), might want to check out the Hugo too. Either way, don't think you'd have any regrets
Edit: fixed some typos
