Amps, Pre's, Integrateds for Focal Scala Evo

This was asked about 10 years ago, much has changed, so I'm bringing this up again. 

What electronics are you using to power your Focal Scala Utopia (or other Utopias)?  What have you heard that matches well.  Most likely will be in a medium-large room.  Not sure what cables, open to ideas.  Source will be Lumin or Aurender

What do/would you use?  What do you like about it.  Pros/Cons? 

By the way, why so little from the reviewers on this (apparently) amazing speaker? 

Thanks!
