As far as cables are concerned, there is no benefit from “audiophile” cables. You can and should buy brand-name, factory assembled and guaranteed cables such as Leviton or Hubbell. Home made cables where you crimp your plugs on to no-name chinese twisted pair cable of unknown quality are to be avoided like the plague. Cat5E is more than sufficient. Cat5 is sufficient. Cat6 is good but not a requirement for gigabit Ethernet.
