$3000 stand mounted speakers?

ATC SCM11/2. Consider adding a small REL sub in a corner. Don’t tell her it’s there.

The Nola can certainly play louder and achieves bigger bass but not necessarily better, just different. The Omega is much faster, images better, completely disappears, and is so dynamic at lower volumes it’s spooky. Single drivers are not for everyone but if you keep them within their range, you are completely rewarded.
Before I settled on the Omega Speakers, I auditioned in my home, the Harbeth 30.2 and Rosso Fiorentino Firesole. Both these speakers are really wonderful. The Harbeth have a beautiful darker tone and are easy to listen to. I completely understand the appeal. The Rosso, which I preferred, have outstanding bass and an unmatched sparkle up top. What the Omega did better was to keep me listening and wanting more. They really love tube amps and are beautiful! I would certainly give Louis at Omega a buzz, he’s easy to talk to.

Reference 3A de Capos  if you don't like the finish on the newer models look for the de Capo i in wood veneerI have used mine only with tubes  35wpc Primaluna (EL34), Vista Audio 84i 10 wpc (EL84) and a 4 wpc Decware  mini torii with 6V6g st

Clean detailed nice bass for a stand mount ( 8.25 in woofer)

I would be looking at some Dynaudio Special 40s. 

Since you already know that you will be using a 40wpc amp in a decently sized room, you should look for speakers that will allow you to play your music at the levels you want with that amount of power.  Generally, this means you will be looking at a speaker that is reasonably efficient.  However, small monitors don't tend to be very efficient due to the laws of physics.  However, there are some exceptions, such as the single driver speakers mentioned above.  

If you can look at slightly larger stand mount speakers, you may be able to find increased efficiency along with deeper bass response that will fill your room.  The Wharfedale Lintons are an example of this (although at a lower price point).  

Good luck and have fun!
