Hello, first time poster here. I did some searching but didn't find anything on point - sorry in advance if I missed it or am not following protocol.
I recently purchased a home with a C4 install from ~2016. It's running a HC800, and we're (my wife) are struggling with the user interface on the iPhone app. We really only use C4 to stream spotify from our phones across ~7 zones, and we also have a surround sound setup that we use to watch our Roku on a Samsung TV. C4 feels like overkill given our use, but I'm told it's really the only viable option short of getting a bunch of Sonos Amps, and a Port for the surround sound receiver. I was speaking with a local C4 rep who suggested we upgrade to a Core3, which, together with install/programming time could be done for around $2,000.
My question for this esteemed group is whether an upgrade makes sense. Will the only change be user experience of using the app? Or is there anything else we'll notice. I thought I read somewhere that HC800 didn't support 4k video, so, if true, would our TV picture improve if running a ROKU through the C4? If your view is we should upgrade, do you agree that Core 3 makes sense vs. Core 5 (which is double the price)? Any thoughts on buying a used Core3?
Thanks for your help!
