Cat 5, 5a, 6, 6a, etc


I was on another thread amongst the non-insiders, and there was discussion regarding ethernet cables.
So, learned gentlemen and ladies, what is your take on how far up the Cat level does it make any difference to audio?
Is there a point of diminishing returns?

Hi Bob,

See my three posts on the first page of the following thread (assuming you have posts sorted oldest first):

I would not assume that a cable having a higher Cat number would necessarily provide better sonics than a cable having a lower Cat number, even if there is a difference. For example, a higher Cat cable is likely to have greater bandwidth than a lower Cat cable. Greater bandwidth will result in faster signal "risetimes" and "falltimes," those terms referring to the amount of time the signal takes to transition between its two voltage states. Faster risetimes and falltimes could very conceivably result in an increased possibility of digital noise finding its way around (i.e., bypassing) the ethernet interface circuit in the receiving device, and coupling via grounds, power supplies, stray capacitances, or other unintended pathways to circuitry further downstream, where it may cause timing jitter or other unwanted effects.

As you’ll see mentioned in one of my posts, a member for whom I have great respect reported several years ago that in his system a considerable sonic improvement resulted from changing a garden variety unshielded ethernet cable to an **inexpensive** shielded type.

I don’t use an ethernet interface in my own system, btw, although my DEQX provides one. Perhaps I will at some point in the future.

Thanks Al.
I was just wondering if I should upgrade the ethernet cable from my ONT box to my router, and the cable from the router to my Memory Player Mini.
That is one long thread, so maybe the answer is in the remaining pages.

When I saw your previous post I was about to respond that pretty much all you were likely to find on the subsequent pages was a lot of controversy.

In any event, IMO whatever differences may result, if any, figure to be highly dependent on the specific designs and technical characteristics of the components being connected. Including (among many other things) signal risetimes and falltimes, which are almost never specified. So aside from the slim possibility that someone might have posted relevant experience somewhere involving the same or similar router, player, and optical terminal, your guess as to the potential benefit is as good as anyone else’s.

Whatever happened to "Cat 10"?
 It was the only "Categorized", cabling that had an architecture and build quality inherent, that not only impressed me. But absolutely, "Floored", me. And that is hard to do.... "Let alone it's listed spec."
  I was sent some to play with after they had finalized the design, "Including a tool specific", "Kit". The cat-10, cabling specs at the time were all purely theoretical though as nothing existed which could actually, "physically",  test it. (Circa 1997)!  As in, "Testing it through to it's theoretical potential".
 Anyone ever learn of it's final disposition? Or even have any exp. with it?
Over the years I have asked after it several times. But except for myself? All seem to think that it never actually, "Physically" existed. At least at one time. I do remember that it was quite expensive. About 50 X, the cost of "Cat 6e" at that time. (They had simply skipped over the development of "Cat 7, & Cat 8", I was told).
