Well, there's the C5 and C5D if you want a more portable JDS Labs product.
Or if you want something that runs on batteries, there is the Pico Power...

Where did those Head-Fi bands come from?
First impressions are the most lasting.
I only had the Fiio X5 for two weeks and I loved it,but the sound from the nano I prefer, warmer and more analogue sounding,great detail,and my DSD collection(all of two freebies)sounded sublime,on a different level than playing the same tracks from my Sony F886 and Fiio X3.
I thought you said you've reached the end of your headfi journey! Stop wasting money!!
