Overkill for small room

Plus one on the Special 40’s.

Oh, and if you’re nuts, welcome to the club.😁

I concur on room treatment, I have an even smaller room with decent size dipole speakers, adding sound treatment to various locations made a huge difference. 
GIKacoustics offers free room treatment advice which I found very helpful. 

I own the Contour 20i's and drive them in a small room with a 25W, Class A, First Watt M2...they sound GREAT. Plenty of dynamics, tight bass, and power at all volumes. These are not that hard to drive. And btw, my amp has a damping factor of 20...zero issues with bass control.

I will pile on and applaud your excellent choice.  They should work well in your room size, set up on proper stands and positioned with care.  You don’t say whether you have electronics, nor what you expect in terms of dynamics, but a pair of 7” woofers cannot be expected to deliver limitless impact no matter the amp.  I would start with a 50-100W high current model. Given the price range of the speakers, a used Michi integrated might be a good place to start.

Good advice about room treatment.  I would suggest getting a mic and using something like REW to measure your room before treating it, and measure after treatment installation.  Or you could use dsp or Dirac or some other digital room correction.  I have no experience with either of the last two.  I have used a mic and REW and that was straight forward.  I assume dsp and Dirac are as well.
