It’s the ones Floyd Toole owns, so that should tell you something. Before reviewing the KEF Blade 2, John Atkinson stated the Salon 2 was his reference speaker.
Room layout/construction does matter as well.
I’d love to hear the Salk SoundScape 12’s in person, they are amazing bang for buck, is a literal full range, and comes in ~100 finish options.
But yeah, those Salk’s and the Blade 2 would be the only competitors I know of.
