During last 10yrs, my speakers evolved from Pro-ac Response 4 to ML Prodigy to MG20.1, then two years ago the SF Stradivari. Earlier this year, after having audition a number of some highly touted contenders within my allocated upgrade budget of 40-60k, I ended up with the MiniII.
Although price wise this may seem a downgrade, but sound wise (in my set-up) there's simply no contest. IMO the MiniII is much more accurate, neutral, fast, transparent, coherent and just as equally musical compared to the more costly Strads.
I also think they are almost a perfect fit for your room (1-2m longer would be more ideal), and given enough quality wattages from the Boulder, they should synergize pretty well. What's 1060's ratings to 8-4ohm btw.? Do home audition one, I have a hunch that you will most likely keep them.
