Yes, looking to install all of those. I would do myself, which I still might, but I don't want to go wireless speakers and I want the install to look clean/professional.
Going to go middle of the road quality wise. We already have a Samsung 4K in the upstairs living room and have been really happy with that, so probably looking at a similar, larger model.
For audio, I have heard/read lots of good stuff about Denon. A must for me too is that is listen to cd's, so I need a good quality cd player as part of the system. Been looking at a Yamaha for that. From what I've read the dvd/blue ray players just aren't very good when it comes to playing cd's. Always loved JVC products for that, but looks like they have gotten out of the home audio business.
Oh yes. Planning on getting a good quality antenna as part of this project too!
