The thermal management stuff on the Nucleuses (what I assume you are referring to) was designed to allow it to operate without a fan, so as to avoid putting mechanical noise into its environment.
Whether or not that stuff has some indirect effect on sound quality via another mechanism is not an area in which we are making any claims.
I’m sure there are other companies that would spin wild stories about sound quality secret sauce if making a product like this, but we’ve never really been in the snake oil business, and we know better than to argue with audiophiles about what makes a difference.
