Technically, yes, this is in the wrong place.
That is the subforum for whole home audio (and video).
You have indicated you are building a new home. This will make many people jealous because you have the opportunity to wire your home without stripping your home to the studs! Drop wire everywhere. Speaker wire, network cable.. be liberal. Who knows what rooms you will want to have security cameras or in wall speakers in the future. If you pre-wire, it will be IMMENSELY easier to add to your smart home. Check out this informative video:
Also, unless you are made of money (and if you think your Denon 8500 needs an upgrade, you might be lol
), I tend to think video distribution is no longer needed. It is far easier, economical, and modular, to simply place streaming devices (apple tv, roku, shield, fire stick, whatever...) at each TV rather than investing in an HDMI matrix. However, if you are prewiring a new construction home, I'd probably go ahead and drop the wires for it because the expense of dropping wires at this stage is basically zero relative to the rest of the system.
If it were up to me, I'd invest in a wired whole home audio system. Something like this: https://www.htd.com/Products/Whole-House-Audio/Lync
which would be a pain to install with sheetrock up, but with new construction would be a breeze. You can also go the SONOS route, but they aren't mutually exclusive. I know a guy who has an HTD Lync system and uses a SONOS port so whenever he wants to use the SONOS ecosystem, he can (and he can hear it in any of his 12 audio zones). I'd strongly recommend dropping the wires during construction as to not "close any doors"
As an example to the power of the HTD Lync whole home audio system, think of this. You get 6 centrally located inputs that can play to any zone. In addition, at each zone you get one input which can also be played in any zone. For instance, imagine a guest bedroom with a TV where you have installed a pair of in-wall or in-ceiling speakers. You can use the audio from the TV and use that as your input to the whole home audio system... so the audio from the guest bedroom can be broadcast out to the pool if you so desire.
