Ethernet Cables, do they make a difference?

@markalarsen 
Oh.... So your explanation has nothing to do with anything happening inside the cable itself. It only makes a difference if you're running them parallel to other cables, eh? What a crock of crap.

Click the link. That's a SCSI Ultra320 cable. That's not moire effect you're seeing. That's twisted signaling pairs. All SCSI parallel cables required that at the 40MHz bus speed and faster. I should know because I've been building machines with SCSI since the days of SCSI 2. Just like Ethernet, the faster varieties of SCSI use twisted pair wiring to mitigate crosstalk and differential signalling to mitigate inductance effects in the wire. Ethernet cables generally see differential voltages of 1 volt or less. That's comparable to the line level voltages of an interconnect. If you're getting crosstalk effects from an Ethernet cable that's audible, your other cables are garbage.

Hello Brad,

Do you individually measure each of your cables on a tester (e.g. Fluke) and include the results? Have you by any chance examined signal integrity and PHY power consumption with your cables?

Have you compared different lengths of your own cable, such as 0.5 meters vs. 2 meters? Did you find any differences? If so, which one was preferred?

@zoom25 also important to descrime the differences observed, i.e. noise, distortion, clarity, etc.

“....descrime the noise, distortion, etc.” 

Excellent Freudian slip.

clearthink - And you want me to compare this cheap inferior wire not made to audio purposed for $25K USD to what cable another one from your Home Depot store?

@clearthink -

I understand you are now attempting to "save face" by pretending you have misunderstood what it is you and I have been discussing.

Ask yourself why have I insisted on lawyers, a contract and an escrow account. It is to avoid any misunderstanding by clarifying the details in writing and be in a position to enforce the release of funds (if and when we arrive at that point).

That said, the answer to your question is "no". The idea is not to compare the ordinary wire to something else. It is to compare it to itself, once its orientation has been changed. You know, reversed. This means plus/minus polarity is the same, however, the ends of the wire that are on the amp in test "a" are subsequently attached to the speaker terminals in test "b". Also, the ends of the same wire that are on the speaker in test "a" are attached to the amp terminals in test "b". Therefore, whatever the wire, there can be only one spool of it involved. From the spool we shall derive the rest of whatever wiring is required (likely 6 sets).

Your mission, should you choose to accept it, is to *reliably* determine that you are hearing a difference between test "a" and test "b" (i.e. know whether or not the wire orientation is/was or is/was not reversed).

See the following response to Geoff, which addresses *reliably*.
