This is one of those products that you purchase even if you don't need! Ive got mine through on preorder. Planning to use as an alternative flavour to my delta sigma smsl do300ex dac. Looking to use it to tame some MA silver 100 7g speakers, hopefully creating more synergy.
I haven't seen any disassembly yet. FiiO posted pretty nice 3D render of internals on their channel, so if you're just curious, you can check it. If you want to "double-check", then you'll have to wait for someone who'll dig inside
