ETHERNET CABLES


When using ethernet for hooking up streaming devices and dacs, what cat level of  ethernet cable should be used. Is there any sonic improvement by going to a  higher dollar cat 7 or 8 cable?

I did notice a sonic difference when purchasing and switching to an ethernet Audioquest cable (it wasn't even their top of the line). It was only a 3' cable, but I swear I heard an improved difference. That cable feeds my desktop computer, which I use for streaming (has a decent soundcard in it). My other Cat 8 cables (I don't think the Audioquest cable was rated Cat 8) I use for TV ethernet streaming delivery, so I couldn't tell you if they improve audio performance or not. When running long distances, I'm a fan of shielded ethernet cables, but to reap that benefit, you must make sure they are in fact tied to ground (not always easy). 

I went from Supra (Cat 8) to Wireworld Starlight 8 to Audioquest Vodka (Cat 7). Each step was an audible improvement, especially the move up to the Vodka, better than the two prior Cat 8's, FWIW the Cat level between 7 and 8 seems to be irrelevant. At some point I will try the WW Platinum Starlight 8. Neal

Ethernet connections have an isolation transformer at each end; however, Cat 8 cables are shielded and can transfer noise via the shield from one component to another. That is not true of Cat 5e, 6, or 7, any of which has rated bandwidth far exceeding what's needed for home audio.

I second the recommendation for cables supplied and tested by Blue Jeans Cables. Though personally, I’ve never found any significant differences in sound when switching Ethernet cables -- except for one that failed completely. That was a difference -- no sound!

Thanks Mike, I appreciate your feedback. I will need a 35' to 50' length so that is why I am questioning whether it's worth to buy a higher quality cable.
