I'm new to all of this and was looking to slowly build a decent system for my living room. I was contemplating the Denon AVR-X4400H and then either going with 4 R28F (2 front 2 rear, not much of a fan for bookshelf speakers), sub, center, and then later on down the line maybe add some upfiring speakers for atmos. Thoughts, suggestions, etc. Is the Denon good enough to handle that?
