Noisy ethernet cables


When I use any ethernet cable other than the stock cable that came with my Bluesound Node2 I get much noise. I have tried three, the latest being a Nordost Heimdall2. The other 2 I heard about here, Monoprice and Supra both cat8. ???

Ethernet over UTP offers galvanic isolation from transformer coupling. Any noise you are noticing must therefore be from EMI/RFI picked up by the cable. The fact that multiple cables exhibit noise confirms this.

I would try to locate sources of interference.

If the cable that came with the Node isn't noisy why not use it? Probably shielded 5e cable. 

Never had a noisy ethernet cable, I'm using Blue Jeans right now a fantastic sounding ethernet cable for very little $$.

Just a guess the stock cable is not a shielded Ethernet cable. All the other cables you mentioned in your OP and post are shielded.

Your problem may be caused by a ground loop. The RJ45 shielded plugs on each end of the shielded cable(s) are connected at both ends to the shield.
