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.
