Sonus Faber Olympica Nova 2 vs Nova 3

Hav8ng owned these speakers , the Pretty New Sonetto G2-8

has tons of their flagships trickle down technologies , and for sure better in several areas  for Everything is New , and $9k retail  is easilly in the $15k+ range 

read a few reviews and go to their website to see exactly what I am saying 

the only thing better is the solid wood panels on the older ones ,vs the Veneer

that being said they do veneers very well !!

Definitely Nova 3. Your room is not the small and the 3 brings complete coherence to a deeper bass level.  I owned Olympica 3 for many years. They are great speakers. 

My best advice is to be patient. The Olympica Nova series was released late 2018 so an update should be upcoming. Was very close to purchasing a Nova 2 in 2021 but inadequate dynamics and mid-bass refinement were deal breakers. What Sonus Faber should also improve is the efficiency rating along with an overall refinement that mirrors the current Homage series. 

My view is -- I always go for the "more bass" output.

I have the Nova 3 in a similar sized room placed approximately 2’ from the back wall. They offer a neutral yet very detailed musical experience. Their bass response and dynamics are superior to the 2’s and if your budget allows I would just go for it.
