Denon 6500 - Am I crazy?


**I know everything is subjective and it all comes down to what I think sounds 'good', but I figured there are some valued opinions here I would love to hear.

Amateur here and first-timer to the forums, but wanting to learn more.  If I land on B&W 704 S2s like I'm eyeing AND I want to leave the door open for creating a Surround/Theater experience for when I watch movies am I being crazy going for something like the AVC-X6500H (140W when driving 2ch @ 8 ohms)?  

I see thousands of 2-channel amps (and I have a decent one that I ordered but hasn't arrived) that people use.  Is that because they are MARKEDLY superior to a multi-channel amp like this one or is because they have no desire for surround and they just pick up a nice 2-ch amp?

I ask because I'm building a theater room for my basement and I want to be able to drive my 704s (not bought yet) but if I'm selling myself extremely short by buying this amp I want to know.

Thank you@arcticdeth, will keep in mind!

@hshifi Probably a silly question, but if I am only using one sub then I assume it does not matter which side I put it on (L or R)?  

If I put it on L, would that mean that all L channel audio is being sent first to my sub, then to my L speaker and all R channel audio is being sent completely to my R channel?  It would seem I would have imbalance in bass, or am I thinking too much into it.
I have a Denon based 5.1 theater system....its ok but only ok. My big system is in another room for serious listening.
re: sub....lows are non directional
