Hello to all. This is my first post. Just moved to a larger home. I plan to install Polk in-wall speakers; two in kitchen and two in L/D area. My Denon is older and I'd like to replace it. Just a few basic requirements: must be able to power speakers "A", or "B" or both seta at the same time. This new receiver will not be needed for video as we have a sound bar. And I've owned three Denons in the past. Mostly listening at a moderate level; no heavy metal. Any ideas are appreciated. Thanks to all.
