Just had a quick look inside AK10, battery is user replaceable as it is plug and play type of thing. There is a little bit of empty room inside the device which moding community can use.
I for one find the low end of AK10 more pronounced than AK120, it is much more meaty than AK120. Volume wise I think it has just about the same volume as AK120. All and all AK120 wins because of soundstage, the rest I honestly thing AK10 does quiet right.
Perhaps the major issue with AK10 that it is not as quiet as AK120 at louder volumes. I can hear a faint sort of humming sound.
Okay it seems that the humming sound is not there when I have the ipod set on flight mod. I need to conform this but for now I think it is a poor sheilding issue.
