Will Sonus Faber Serafino G2 be too much speaker for my space?

Hello Audiogonners.  I am a lover of Sonus Faber speakers and currently have Olympica Nova III.  I have an opportunity to purchase a mint pair of Serafino G2's locally for a good price.  Based on my experience listening, and all the comparisons between the two models, I am convinced the S2's are a better more engaging speaker, with better bass and more resolution up top.  I don't want to afford the next level Amati's.  

My only concern is the Serafino might be too much speaker for my space. I don't have the ability to try them in my space before buying.  I've included my system with a photo of my space in my profile.  It is 14'x20' with 9' ceiling. I have no room treatments except the WAF variety (carpets, drapes, upholstery) and it has to stay that way.  The Olympica's sound fine and do not overpower the space.  Do you think the Serafino's will be too much?  Anyone with experience with the Serafino in a space approximately of this size?  I've read all the reviews I can find and cannot find an answer to this question.  Thanks in advance for your help.
