Looks like the Denon will do what you want. You'd probably not use the Onkyo's Dolby Atmos which would require more speakers in the room, ceiling mounted. The Denon has Wyfi and the internet tuner is built in which is cool. The Denon claims to be 4 ohm compatible so should drive your speakers alright, although it looks like it only is 75 real watts per channel, but with a sub and if you don't listen terribly loud you should be fine. It is Bluetooth compatible so will play music from phone or tablet, and also a USB input that plays music files. So, I think you did good.
