Glad to hear I ain't the only ZS10 Pro user here, got it last week together with a protective case and spare cable for it. Just got my iBasso DC02 today and it worked with my phone straight out of the box. Now, gonna have to 'burn in' the ZS10 Pro and the DC02 (or, maybe listen to them long enough to adjust to their interpretation of sound/music.....anyway, the DC02 gets more than loud enough for my usage.
