Sonus Faber Olympica nova 2 VS Sonus Faber Cremona M Loudspeaker vs

I am looking to upgrade my speakers, I am looking at either used Sonus Faber Olympica 2, or if I can find at a good price the Olympica Nova 2, or a used pair of Sonus Faber Cremona M Loudspeaker

I am also looking at the GoldenEar Triton 2 plus, or One R

wondering if anyone has heard these and has an opinion. 

Mostly Hard Rock some Metal, Jazz Rock Fusion, and once and a while Jazz 

Thank you
