Ethernet Cables, do they make a difference?

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.

Optic fibre is good for data and low level audio. I believe @geoffkait stated that jitter was a debilitating effect on music over OF. I would imagine that this to will be overcome in the future.

A Google search for “signal speed copper vs fiber optic cable” turns up this explanation at the top of the page. Find the mistakes.

“Fiber optic transmission is faster: Fiber optic versus copper wire transmission can be boiled down to the speed of photons versus the speed of electrons. ... And while fiber optic cables don’t travel at the speed of light, they come very close — only about 31 percent slower.”

Extra credit. Does an electromagnetic wave travel faster through water or glass?

I have no audio on Ethernet but I can't imagine the quality of the cable NOT having some influence. I work for a company that  we specialize in Industrial Automation products. Everything talks to one another over Ethernet or in my world Profinet. PLC;s talking to Variable Frequency Drives, Industrial PC's etc. We DO NOT use your Radio Shack / Walmart cables. We use a industrialized cable that is shielded to protect the signals from noise. We actually terminate the cables with shielded Metal connectors made specifically for this cable. I am not sure you would need that, but if you think you would let me know.
