Upgrade from B&W 802D1 to Focal Utopia Scala Evo

No amount of snake oil products will make either of those overly bright and harsh speakers sound listenable. Start over and consider Dynaudio, PSB, or even ATC passives.

When I bought my Sopra 3 a few months ago the dealer had the Scala in the sound room.   I wouldn’t describe either as bright . I’ve not experienced   Listener fatigue despite multiple 4 and 5hour listening sessions 

If you had the chance to upgrade from the B&W 802D1..: Yes!  
which would you choose?  anything
and why? it sounds better

I would like to know what everyone likes about the B&W  802D1 and what everone likes about the Focal Scala Evo........please

The Focals are more sensitive. By a fair amount. Easier to drive. I would go with them. I am also not a fan of B&W. Not a hater just not in the cult.
