The Serafino2 has been out ,I owned the Olympia Nova 3 the Serafino 2 is much more refined .
for less money you should absolutely take a look at the Borresen X3 speakers .
a Ton of trickle down technologies other speakers Donot have . The ribbon with wave guide 1-100 of a gram very powerful neodymium magnets ,and drivers 5x faster by design with type of carbon fiber,sandwich design ,for $11k ,120 lbs each ,comes in only gloss black or gloss white . Read a few reviews I have heard much of their line up . A huge open soundstage, detailed loudspeaker , with fast tight bass into the mid 30hz range ,btw most recordings don’t go lower then that. At least read a few reviews then go have a audition. These are much better then the nova 3 I owned . The Sonus Faber are more beautiful To look at that’s their only + .
