Thank you for sharing and that looks like a nice system. I like Polk they make a really nice speaker. I have a pair of Polk bookshelf speakers and a Polk sub in my bedroom for my pc that is hooked up to a 43" 4K LG display. What kind of movies do you usually watch? It may only be a PB-1000 but I bet you get some good bass out of it being an SVS. Let me know how the Denon works out for you. I have always like Denon as well and still have some Denon gear. My first surround piece was a Denon pro logic and that is how I got into surround sound. Of course you know I have the Marantz and they are under the Sound United umbrella with Denon, Polk, Definitive Technology, Boston Acoustics and Classe Audio. It seems according the the news from Sound United they will no longer be purchasing Pioneer and Onkyo. When it is time to make the jump to a 4K display I hope you get something that will give you a great picture.
