Sonas Faber OLYMPICA versions

Note that the iii are the latest version Nova and the ii are not. I auditioned the Nova ii and iii.  Same basic house sound but the iii’s are much fuller and go deeper.  Both are very nice speakers but I think the iii’s would probably be better for your room size.  You’d probably be very happy with the ii’s unless of course you listened to the iii’s.

I bought a used pair of Sonus Faber Serafino speakers for $11,500. They are in perfect condition and sound fantastic. Highly recommend them.

I own and love my Olympica II in my small room, but for your size room, I would definitely go with the Olympica III.  They should work perfect for you.  

I can't speak to the past versions of the Olympicas but I did an extensive demo with the Nova 3s and a Hegel H390.  I thought the pairing was excellent.  The Nova presentation was a tad too warm for me so I ultimately went in a different direction but I can see how the sound would be very appealing to many listeners.  I listened a lot of different speakers and while the Novas are expensive they seem to be worth the money compared to the competitors.  Side note, make sure you're going digital out of the Node and are utilizing the very good DAC in your Hegel.  Good luck and cheers.
