Want to Upgrade Speakers from Paradigm

I have had my Paradigm Signature 6 version 3's since 2012 and I am getting the upgrade bug.  The honest main motivation is I am tired of their looks: outrigger feet; the gray plates; cherry veneer.  I do like their slim low profile.   I am pretty happy with the sound but I am sure they are not the end all of speakers.  I spent $6K for them and adjusted for inflation, that is about $7.2K today.  However, I believe high end audio does not follow inflation and increases at a much higher rate.  So my question is how much in your opinion would I need to spend today to better the sound.  I really like the looks of the Sonus Fabers such as the Olympica Nova 3 which retail at $13,500.  How would my Paradigms compare to them or maybe Revels?

Thank you!

Rest of my equipment is Benchmark DAC3 and AHB2 amp with Macbook as streamer.
