So Focal Clear over Arya and Diana as an end game, nice and tight recommendation.All depends on your preference. I like certain Focal headphones over HD800 or 800S.
But those are also pretty expensive, but far more practical.
If I ever go truly all out, it will be Abyss Diana for sure.
IMHO Focal headphones are overshadowed by their speakers.
Focal clear is a brilliant and beautiful piece of art.
I know Utopia should be the next logical upgrade, but if you hear Diana once...it will win you over.
