Where is the measurement to prove that A10 needs bigger current, or should I take your (well, nor your, but Sony's) words for it? Or in another way of saying it - where is the proof that the thinner cable is limiting the current flow, which degrades its performance? If cable is such a terrible media for current flow, why not just mount the battery directly onto the PCB with big copper contact? Surely a a thick and even shorter copper plate beats cable for current flow?
It is too easy to claim something to work, even if the underlying principle might be sound, then to prove it actually working. On the other hand, have you seen Sony's engineer giving a presentation that a piece of metal spacer (which is just used as spacer, not really conducting any signal nor part of the circuit) and how the sound of the metal affects their choice? That's laughable to a point of being sad.
Don't get me wrong - I like my A15 and probably uses it the most among all the DAP I current have. But that doesn't mean I'll buy into everything Sony said.

As to the actual question at hand
has anybody noticed benefits from burn-in with the A10 series? A few people have said so, can't say I have noticed any change.
Might just be those Phillips like a little more power? Or just suddenly switching sources can be a bit of a shock (not to mention by most accounts the x3ii is a great DAP that measures better and you might just prefer it). I don't have them any more, but my favorite pairing so far has been with the ATH-IM02- I prefered them with the walkman to my clip+, though I think they had a bit fuller low-end with the +, and they sounded markedly worse out of my JDS C5D for some reason- I'm guessing the C5D's dac because using it as an amp with the Walkman line out was OK.
Overall I think the Walkman's been perfectly adequate for most of the earphones I've tried, though with a few pairs I've noticed advantages with C5D and Clip+, though not always consistently between the two and I'm not volume matching so... ＼（〇_ｏ）／
