What about wall plate connections?

So I do about everything to clean up my digital front end.

Tonight I am running 15m Supra cables to my audio space.  (no thanks on advising fibre please).  What about the eheapo plate on the wall?  My nice Supra cat8 cable mates with one side of a female connector, and the other side connects with my EtherRegen or Muon filter Cable.

shouldn't there be a better plate?
