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

my dealer says i should really purchase the IsoAcoustics BAIA I Neo Isolation Feet for my speakers.... that the difference is very noticeable, any thoughts on this for the Focal scala evo speakers?

I have found that using the appropriate IsoAcoustics isolation feet improves every speaker in very noticable ways.  By all means follow your dealer's advice in this matter.

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
