Best speakers for a small room

I put Thiel CS3.7 floor stander into a 12 x 11 x 9 room. I needed to spend $700 to get acoustic treatments from GIK to make this work. I also needed to move reflective surfaces as far away from the speakers. I also do not have anything large in-between the speakers, just an amp. A bookshelf with books behind the speakers also helped.

Since I am a ROON user I was able to use DSP via professionally crafted CONVOLUTION filters. That can make almost ANY speaker work in my space. However, after rearranging the reflective items and adding 1 additional acoustic panel in front of my CD rack I was able to disable the CONVOLUTION filter. I think I am hearing the best possible sound in my room. A bigger room will get more out of the speaker but what I have now is satisfying.

Even though I no longer use the filter, the company that remotely did my DSP filter was this one.

They give you step-by-step instructions on how to measure your room using REW software and a mic. You give them the output files and they run that data through some very complicated software resulting in the DSP convolution files.

The other two options under 10K for bookshelves that really warrant serious considerations are AudioVector R1 Arrete and Yamaha NS3000. I listened to both and they are very fun to listen to and are definitely flagship quality. 

What country are you in? I was not able to locate the NS3000 in the USA, but I can get it shipped to the USA from Toronto, Canada.

When I demoed the NS5000 locally I thought it was a very nice sounding speaker. It is too big for my office but the NS3000 is high on my list.

My room is only 12x11x9. I am currently using the KEF LS50 + KEF KC62 sub in this small room. Would the NS3000 be a substantial step up from my current gear. I would assume I would keep the KC62 sub.
