Sonus Faber Olympica 3 or Olympica Nova 2 ?

Everyone brings their own biases to these discussions- me included. The OP didn’t ask for recommendations on other brands. Nevertheless, I’m sure they’d be well received if offered genuinely.  
On the other hand, recommendations are frequently offered by forum participants looking for validation of their own decisions and biases. Fine. But, it’s rude when they’re volunteered while also being so dismissive to what the OP is already strongly considering- and is a brand she/he already owns. It also does nothing to further the sense of community of the forum, or our collective knowledge. 
Lastly, in this case, it would be an opinion that seems to fly in the face of SF’s very large and loyal customer base.

Consider my second line removed from my post.

In your small room, the O 3's are almost certainly too much energy as there's just no way to get them out of the corner and side walls without them being in your lap.  I imagine the bass will be very boomy in your room.  An audio system design starts with the room and then to choose speakers to integrate well into that room.

I listened to a few SF speakers at two dealers in 2018.  For a short time, I had the Olympica 1 in my listening room and it had wonderful clarity and detail in the upper 5-6 octaves.  I was very impressed.  At the dealer, these easily outperformed the B&W and Dynaudio at the same size and price points with their spatial presentation.  As expected, the bottom two octaves were all but gone but I was a bit surprised the lower mids were somewhat lacking natural presence.  And my system is very much designed around getting the middle 6 or so octaves to be magic.  Perhaps the O II would fill in that lower frequency coverage without overpowering your room with bass energy.

Ultimately I bought the Amati Futura.  These speakers are insanely picky about amplifiers just to drive the woofers to their performance capability.  That was absolutely not the case with the O 1's.  And I imagine the O 2's will not be so demanding either.  But the 3's might be a similar amp issue as the Amati.  I would research the O 2....or the O1 with a nice subwoofer which is what a lot of Guarneri owners do and write in these forums about having great results.

And a final word on the amplifier here.  Don't spend your money on these speakers if you are just going to throw a cheap amp in the mix.  Expect to pay $3-5k on the used market for a solid state amp with serious current drive.  It is not about specified power ratings.....it is about current drive capability.

Hi guys,
today was a nice day in south east Mas. I called a few people (I mean dealers) and I have gotten a quote for O Nova 2 for $7500,
not bed. Somebody suggested to check Tannoy, Fine. I don’t see these dealers in my area. Shipping staff beck in case I don’t like it can be expensive. I will stick with SF. Hi jafox, your post is very knowledgeable. I have a chance to move the speakers to bigger rooms 20x15. My amp is Yamaha as3000, it can dip down to 4 ohms.
Thank again guys, I will tell you what my choice is going to be.
Best.
