Your thread title mentions wall plate or direct connection. You’re asking about a 5.1 wall plate, which tells me you’re talking about the location behind the equipment rack? If that’s the case, why bother? Sure they’re pretty, but behind the equipment rack no one is going to see it anyway, so why bother? It’s just added expense and connectors that aren’t adding anything of value.
