Franco Serblin Accordo - anyone hear it?

I am in the market for new monitors. I really like the Sonus Faber house sound so am leaning towards new Auditor M's or the Olympica I's. I just became aware of the Franco Serblin Accordos. Has anyone heard these?

I'd speak to Harris4crna about the Franco Serblin speakers.
He owns the Ktema and might have heard the Accordos.
Here's his posts about the Ktema.
