Sonus Faber Olympica Nova 2 vs Nova 3

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. 

Thanks for the responses - I have the budget - i am just concerned that they will look to big in the room (compared to the Nova 2). 

As far as being patient - i agree - but the think is I currently have no speakers or system at all in my new apartment - so waiting for SF to update the Nova speakers can mean having no music at all for years.
