Dedicated room suggestions

Try out the Room EQ Wizard's room simulator which should help you compare.

Also the AM Acoustics room mode calculator will let you see where the worst modes will be.  Combined they can be great starting points.

Hey @chiadrum , there is a video in the other thread you were just in where Anthony Grimani discusses room treatments. His website is below and they sell both individual treatments as well as kits for entire rooms. I followed the recommendation in the video and got great results. You can see the measurements of my treated room in my system profile. I would definitely e-mail them or call if you like what you see in the video. Anthony corresponded with me via e-mail and was very helpful. If you post some pics of the room it would be better. You need to take into consideration where the windows are, open doorways, etc. Those speakers will likely be better off well into the room.

Thanks for the suggestions guys. I will check out the tools that you mentioned.  Regarding the room layout, the entry door is to the left center of the room while the window is centered on the outer wall. 
When you step in, on your left a small closet will need to be framed to cover some HVAC ductwork. I was thinking about a soundproof window cover and a sound engineer friend of mine recommended an outdoor door as well. 
I snapped some pics but from my phone at least they want a URL to post pics?

My laptop is charging. I’ll try to post pics later. 
 

I should also mention that with certain recordings (only the worst recordings, everything else is fine) with my current setup I am getting some harshness. But my setup is pretty pathetic. The speakers are maybe 4’ apart and I am sitting maybe 8’ away. My new room will allow me to properly space  the speakers and sit much further away if that provides the optimal results

I heard none of that harshness when I demoed the amp and streamer/dac. That was in a large room with the speakers far off the wall and spread apart as Klipsch recommends. Literally listening to the exact same recordings. 
 

You can setup a virtual system in your profile and post pics there. That harshness will likely resolve once you get your room right. Dampening sound around the window is a good idea if is noisy outside. The first thing is to orient your speakers and MLP. The angle is very important. As for which wall to face glass is not acoustic friendly. There are ways to treat windows but if you can keep the window behind or away from the space between you and the speakers its a plus. I know you are doing 2 channel not atmos but this diagram with the angles of the left and right speakers is a good layout:
