Same here (except for the cables - I don’t have a high opinion of some of the very expensive cables which I have not found offer a balanced presentation of acoustic instruments, but a good quality screened cable - e.g. Belden CatSnake Cat5e or Cat6a but with screen not connected - definitely sounds better in my system than either the very expensive cables or the cheapies, including the solid performers like Blue Jeans Cat6a). Either a Cisco Catalyst 2960 PD switch with bundled external power supply or Uptone EtherRegen sounds significantly better in my system (in that order, EtherRegen best) - more natural in tone, texture, attack and decay, more extended and with a more in-the-room soundstage than even the very good Netgear GS105. You can get the Cisco switches second hand without paying a fortune.
Note, however, that these are switches, not routers.
