Ethernet cable question


OK, at the risk of starting a big debate, I have just a dumb question: I see a lot of post talking about Supra 8 and Wireworld ethernet cables, so are you talking about cables making a direct run from your router? I have Cat 5 run throughout my house by me when our home was built 8 years ago. Everything is finished in the home and my sound room is not real close to where I have my network router/modem. So does the ethernet cable going from the wall to my Node 2i make any difference if inside the wall is only Cat5e?

Which do you have Cat 5 or 5e, you mention both? Cat 5 is susceptible to crosstalk 5e not so much. If it's Cat 5 your wifi might sound better, 5e I would  check connections etc... I have Cat6 (compareable to 5e) never noticed a difference except for occasional dropout with wifi.

There is a designer from Sweden makes CAT8 and claims you can run it as long as you want.  Supra Cables. Find them on Ebay. I got my USB from them and the noise I was used to disappeard. He twists the power leads and the data leads and adds a separate shield. In fact this cable made a bigger improvement than the ifi iSilencer+.

I have a 80 feet Belden Cat7 run from the router to the streamer. When I installed  SOtm sNH-10G network switch and dCBL-Cat 7 ethernet cable next to the DAC. Awesome improvements, so much less muddy, overall staging so relax and distinctive. This prompt me to add a cheaper Angel silent bonn n8 network switch next to the router using the ethernet cable provided by the bonn n8 kit. Again there was a step improvement.
