I acquired a Himedia Q10pro!

Q16 and Q5ii still in good use.

This Q10pro works with 4K AVR and 4K TV.

My first findings with Q10pro, 2/16gb, android 7:

GENERAL
.. solid box, stays cool unlike q16 which gets quite hot if w/o mini fan.
.. new launcher is simple and functional, good.
.. connectivity, wifi, just the same as q16, q5ii.
.. HDD slot is simple - I put a 7 yr old old unit in there, works good.
.. playback with native media center or file manager as usual, as promised - 2160p 60fps, HD audio, hevc265, 10bit, BDMV - all good. Yet to test DD Atmos, DTSX.
KODI
.. I installed kodi 17.0 rc3 in there, used org.xbmc.org from q16, works good. By the way, Kodi 17 is very nice looking!
.. 4k, hevc265, 10 bit streams from Quasar, OK.
.. but there can only be 2.0 audio from the addons at this time - a Kodi 17 (not with kodi 16.1) issue with androids. Read that himedia will be coming up with a fix for this kodi 17 multi channel/hd audio stream issues. USB playback is fine with the wrapper set to player and audio passthrough enabled.
Perhaps because I already know quite a bit about himedia Q series boxes, I expected nothing less. It will be a shock for me if I encounter funny problems!
One thing I am aware is that the pleasant experience with the box right from the start is not something to be taken for granted.

Q16 users looking for an upgrade, take note - Q10pro can do the following that Q16 cannot:
.. Android 5, 6 or 7
.. HDR, DTSX (according to specs)
.. Kodi 17 (requires android 5 and above)
.. stream kodi 4k, hevc265, 10 bit videos

Q10pro is a “serious” android box. Certainly a great choice for those looking to great playback of UHD4K and HD AUDIO files besides all the usuals.

Yes, the device already working with ATMOS 7.1 since last generation of Q10. DTX:X works as well.

Just pmed to you the price, we are selling firm price to save our time to serve our customer post sales support. Hope you understand.

i do not have the equipment to test atmos, dtsx or HDR.

just uhd4k, 10bit, dtshdma and ddtruehd.
