I'm pretty sold on the Denon. Keeping it simple, call the room 10 x 20. 8 foot ceilings. Yes in the US. Any reason not to go with the Klipsch? Costco has this:

and then purchase separately a Klipsch sub for around $300?
I guess the real question I should be asking is, is the money better spent investing in the speakers or the receiver? Your recommendation is a $350 receiver + $2300 speakers. I viewed it as an equal split: $1200 receiver + ~$1400 in speakers? What's the right play?
