So, I recently completed my home theater setup and I found out that while my receiver (Onkyo TX-NR686) does indeed support Dolby Atmos and I have set up the height speakers for it, my TV does not have atmos passthrough. I did some research and found out that an Android TV Box would be my next best solution. As much as I wish I could get the Nvidia Shield, it's not within my budget but the Xiaomi Mi Box is though I'm not sure whether I should get the 2016 Mi Box 3 or the 2018 Mi Box S. I mainly intend to use it to play TrueHD/Atmos movies from my external hard drive but I may stream on it every once in a while.
Mibox s will get updates longer
