Sonus Faber Cremona Auditor M upgrade to Sonus Faber Guarneri Evolotions

Hello All!
Currently driving SF Cremona Auditor M's paired with two REL G-2 subs with McIntosh 601 monoblocks with C-2300 tube pre amp.  Very 3 D, holographic presentation with great detail, imaging and focus.  IMO the Cremona Auditor M's are a sleeper....just an incredible performer that gets little recognition....Having said that.....couldn't resist ordering a pair of SF Guarneri  Evolution's.  Wondering if anyone has had experience with these particular speakers?   At four times the to be better, right? :)
