I'm also interested in comparison of the Serafino vs Olympica nova line. From what I can tell, many people claim somewhere in these two lines is where the "real Sonus Faber sound" is, which I feel is a bit nonsensical. SF offers many speaker lines with their name on them, afterall.
If anyone could comment on this: the only experience I have in my own listening area consist of Dynaudio C1 Platinum and Elac Solano floorstand models. Both of these models are definitely on the polite side. I wonder how similar or different Serafinos would be. Ultimately I'm after a clean, natural, and transparent sound over all else.
