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.
