Overall NAD and Thiel 2.4s are a great bang for the buck system in that room, and might even embarass some of the more pompous audio jewelry systems out there.
Regarding the 3.6s, I am running the CS 3.6s in a small room, but I would advise against powering them with anything less than 200 wpc. During loud (95db) passages my CJ MF-2500 sounds strained, and I am actually thinking about upping the power once my summer bonus arrives. You may get by at power volumes, but my best guess is you'll still hear the NAD's proverbial "cockpit shaking". The 2.4's would be an easier load and have much of the same characteristics as the 3.6s, minus the deep bass.
Good luck on your audio journey,
