Which Amp? Onkyo, Emotiva, Marantz, etc.

Does that 32 mean -32, or 32db below reference? or is it 32 out of a max like 80 or 100? Either way, with your size room that's not considered very loud and you wouldn't need 400 watts per speaker IMO.

If receiver I'd tend to lean towards the Denon 4520. Or if you're feeling a little adventurous, get a separate 5 channel amp like the Emotiva XPA-5 or Outlaw Audio 7500. Then you could get a cheaper Denon like the X4000. These Denon's both have the top of the line room correction from Audyssey and that alone will amaze you compared what you are used to.

I highly recommend the Emotiva products. My friend had an XPA-2 powering Maggies via a fancy tube preamp and I was amazed at the quality of sound it produced. Considerably better than the B&K amp it replaced.
I ended up purchasing the XPA-200 amp on sale for $419 shipped to my door. I'm using it to power some home brew Usher passive subs to supplement my main Usher speakers. I could not be happier. A big thumbs up for Emotiva. They also hold their value reasonably should you decide to sell.

Well, I"d stay away from their processors. Also better to get speakers from a company that specializes in them only.

Thank you all for providing your valuable responses. I built on yours & started digging further. Read tonnes & tonnes of reviews & forum discussions.

First of all, Receiver route is definitely out. I do know that I don't need very High Power. But I anticipate SQ to go up too in high-end Amps.

So, here are the final Amp contenders with my preferences. Let me know if I am going off (I could be after burying myself in my Laptop for the last 3 days) :)
1.) Parasound A 51
1.) Emotiva XPR-5
2.) ATI 2005
2.) Outlaw 7500 or 755
2.) Parasound 5250 or 5125
2.) Theta Digital Intrepid
3.) Anthem MCA-50

Now, it all boils down to what I can get in my budget & in a decent condition.
