If someone hears something with different network switch, good for them. Who am I to question someone else’s enjoyment. After all, I can’t tell one scotch from another.
But technically should not be any difference. Comparison with cables is not correct. Cables that carry analog signals susceptible to RF noise. They have resistance and capacitance so, combined with one component output and another input impedance they may make small or significant difference. Digital cables, not so much.
Network switch? Tidal stream passes thousands of switches on its way to you. One more won’t make any difference. Besides, there is no "stream". Internet is all chunks, compressed and chopped into packets that are frequently traveling arriving out of order at the destination, some are lost and get re-sent. At the receiving end it all needs to be reconstructed.
That WiFi router you have also does a lot of work and is a network switch.
