Ethernet Cables, do they make a difference?

These naysayers have no freakin clue about how audio works. These guys claim that all digital is just zeros and ones and nothing will have an impact on the sound. Cable sheathing, cable terminations all make a difference. 
Ask these guys why fibre is quieter than copper, and it’s still 1’s and 0’s. When I went fibre to my house, Tidal SQ jumped way up.

I love it when somebody wants to convince the world that they are right by stating they talk to an engineer and he said blah blah blah! I don’t give a rats @$$ What an engineer says, if you have to rely on somebody else’s opinion then you don’t know what you are talking about. Also, There are differences in network cables running into your house. I’m guessing you have copper of some sort, which is noisy. I have fibre and fibre is always going to be less noisy than copper. Ask your guru buddy about that.
Everybody on this thread talks about the speed differences between cat5 to cat8 cables, in reality, it’s more than just speed differences, much more between the different cables. Cat5 speed rating is far more than what you need to transfer digital music. Cat5 has much better throughput than the throughput from a CD player. If you check out the cable sheathing and shielding, it is much better on the cat7 and above cables.
