I know about Letv/LeEco problems and no more official support in future, but at least x900 once had real official support and (Marshmallow) updates, it now has open source code available at htt p://opensource.le.com, and has at least a tiny bit of community support/developement still going on; all of which my secretive "USA" version of x800 has not.
I can get a new LeTV x900 for just 170€. So I was thinking of, maybe, doing this small intermediate "upgrade". I also see x900 huge (screen) size as a (small) advantage - but that alone is not so important to me.
I was asking specific questions if you might help me understand the kind of difference and improvement (if any) I could expect sound-wise, which is the most important part to me :}
If I learn that among other small improvements the LeTV x900 may bring me, there would not also be at least a small improvement in sound quality - then I may as well skip this tiny upgrade... and live on with my x800, wait until LG V20 becomes older technology and cheaper
Thanks for all your great and useful work here
