Do not mix in "Difference between cables" in analog world and "Difference between Ethernet cables" in digital data transmission.
Why not? Did I beak some sacred laws of science? You might’ve missed my note on electromagnetic waves in cables. That’s how information is transferred, all types of information. Even satellite transmissions, which have been digital like forever. 🛰 Hel-loo!

Ah, the old blind test scam raises its ugly head again. I guess it was just a matter of time. They always threaten blind tests but they don’t wait for the results. Which is really the most important part. 😛

@rja good idea. When you borrow - you did not pay yet.
If you do not want to spend extra money without reason you will try to listen more carefully...

Obviously folks who are unable to hear differences in cables need not worry about it. End of debate. Or is it?
Question to self: why is it always the same ones who can’t hear differences in fuses, differences in directionality or differences in cables? 😬 |
How so, Mr Smarty Pants? That’s not much of an argument. If you don’t have an actual argument I’ll understand.

Ethernet cable is digital.
As such it cannot change the quality of the music.
>>>>Sorry, that’s the same illogical argument naysayers have been using for years to try to explain why there can be no differences between digital cables, the ones that connect to the external DAC - because it’s digital. The problem with that illogical argument is all signals - analog OR digital - are electromagnetic waves. As such they are subject to the same cable characteristics as any other cable - geometry, conductor material/purity, dielectric material, directionality, etc.

kosst_amojan"Foggythink, a highly resolving system does reveal the differences in Ethernet cables. A highly flawed system does."
Costco while I completely agree that a highly resolving Music Reproduction System can reveal genuine audible differences in ethernet cables that can be reliably detected in a proper scientific double-blind listening tests I think it less likely to be detectable in what you call here a "highly flawed system." That is not to say that it will never be detectable in your hypothetical "highly flawed system" but statistically I think it is substantially less likely to be reliably detected in such a Music Reproduction System it would depend on the specific system and what exact limitations it possesses that caused it to be "highly flawed" e.g where care the non-linearities noise distortion or other flawed aspects of it’s audible presentation?

Costco, thanks for an almost coherent post. 😬 |

A Google search for “signal speed copper vs fiber optic cable” turns up this explanation at the top of the page. Find the mistakes.
“Fiber optic transmission is faster: Fiber optic versus copper wire transmission can be boiled down to the speed of photons versus the speed of electrons. ... And while fiber optic cables don’t travel at the speed of light, they come very close — only about 31 percent slower.”
Extra credit. Does an electromagnetic wave travel faster through water or glass? |

Optic fibre is good for data and low level audio. I believe @geoffkait stated that jitter was a debilitating effect on music over OF. I would imagine that this to will be overcome in the future.

John Archibald Wheeler and Kip Thorne wrote the definitive book on the subject of gravity many years ago, Gravitation, 1973, 1336 pages. Everybody and his brother now knows that gravity is actually the warping or distorting of spacetime as a consequence of mass. That’s the reason the LIGO Project detected gravity waves a couple years ago. It detected gravity waves created by a merger of two monster size black holes. The LIGO sensors detect ripples in spacetime. The head of the LIGO Project for most of its life was Kip Thorne, former student of Wheeler and co-author of Gravitation.
Addendum for the advanced student: Considering the notion that positrons were electrons that were traveling backwards in time, Wheeler came up in 1940 with his one-electron universe postulate: that there was in fact only one electron, bouncing back and forth in time. His graduate student while was a professor at Princeton, Richard Feynman, found this hard to believe, but the idea that positrons were electrons traveling backwards in time intrigued him and Feynman incorporated the notion of the reversibility of time into his Feynman diagrams.[24]
With Neils Bohr Wheeler helped explain nuclear fission. |

I didn’t even bother to shield the 600VA transformer in my amp. And why?
>>>>I’m guessing monkey see monkey do.
Because Nelson Pass doesn’t bother to.
>>>>Ah, just as I thought.
And it makes virtually no difference.
>>>>and you know this how?
Twisting is generally the safeguard against crosstalk between signal pairs.
>>>>But in the case of transformers the magnetic field is an issue for everything in proximity to the transformer. That’s why shielding is used around transformers. If there’re smart, anyway. You know, the low frequency high permeability stuff.
