Autoframerateswitching with Kodi: Wich AndroidBox is the best for that?

Hey Guys,

wich from this many, many androidboxex works best with Kodi?
Important things for me:

– correct working of autoframerateswitching is a must!
– optical pass through ac3 and dts and over hdmi truehd and dts-hd
– fully supoort kodi
– Controlling Kodi with hdmi cec, so hdmi cec must work
. full hd and 4k support. 4k with working HDR
– things i forgot atm. maybe complete it later.

the box should as far as possible run as plug and play. i want to have so less work then possible!
wich androidbox should i buy for my needs?
thx in advance and sorry for my horrible englishSmile

regards
