If I was absolutely sure that I would never want or need the optical and coaxial inputs, I would probably choose the Move:
1. Smaller and more portable.
2. Excellent sound with either input.
3. Long battery life.
4. Replaceable battery.
5. Ability to use 3 different power sources.
6. User adjustable gain and current settings.
1 - still portable by using a bigger case w/beltclip but will probably be best with a backpack/shoulder pack
2 - Equally excellent sound and multiple inputs coaxial/optical/line-out/usb. can be used with an iRiver iHP-140 going iRiver/optical/D1-dac/D1-amp/headphones.(i have not tested this as of yet, i need an adaptor cable )
3 - Long battery life (Lithium Ion 2A 8.4v) good for your average 300-500 charges
4 - User Replaceable battery with purchase of one through iBasso and a little DIY work.
5 - comes with a charger with the amp. (this one may or may not work with the Move)
6 - op-amp rolling. (I'm pretty sure of this hearing Jamato has opened this baby up!) this will give the user the ability to choose the appropriate sound's they want.
7 - very well built / chassis is one of the best I've personally seen.
