Ethernet Switch and Cables Mania

Totally incorrect, it’s a technique also used by Naim to fine tune firmware by shaping the noise profile of the induced processing noise. Naim have mastered noise shaping to an extent so as to act as a crude tone control and provide more openness etc…

It’s also referred to in the Texas Instruments engineering papers on mitigating the effects of Fast Ethernet noise on connected equipment… Noise shaping is very real… but yes if you are not an electronics engineer I concede it may be hard to understand…

BTW noise shaping will occur with all network cables, irrespective of what they cost… good music and physics doesn’t need to understand the retail price of a streaming lead… but the relatively poorly measured NEXT on the Vodka cable might possibly produce quite a distinctive effect…

Why not go to Chord factory Mike and learn them how to make the best ethernet cable? Your big knowledge will certainly impress them a lot.
They will say: « why have we not thought before on asking Mr Mike Gyver? «

Look forward to hearing how you get on. Not a massive fan of the Telegartner plugs, but the cable should be good.

I thought the Ghent cables were Belden (US) cables with Telegartner (German) terminations. Are you sure?

It’s what I read here. Perhaps it’s not entirely true.

Naim don’t make Ethernet cables. And thanks for your condescension.

The noise profile is in the equipment influenced by the connected cable… if you are genuinely interested I can post an engineering guide again. But you do seem a little hostile, and I can’t quite understand why.
An apology would be nice from you, but I won’t hold my breath…

Are you sure that’s not a reference to the Velcro straps?

There really is no need to resort to sarcasm FR, its bad enough with someone else with that type of attitude. I am not claiming I know anything about anything, I’m just amused by you challenging a paper by a leading electronics company.

I really doubt that this venerable company will say that audioquest diamond or chord music are introducing more noise than cheap ethernet cables. Just that.

You can be amused, but I feel you have not understood what I tried to say.
I will say it in french : Les cables ethernet audiophiles ont pour but de favoriser la qualité du signal. La construction de leur cable et les composants utilisés ont été conçus entre autre pour stopper les bruits parasites pouvant interférer sur le signal. Ils ne vont donc pas engendrer du bruit mais bien au contraire le diminuer fortement.

I imagine you as Obelix, carrying kilometers of BJ cables to the audiophile world :grin:

Thank you, this is the discussion I’m interested in. Specifically if we can observe any consistent truths wrt the specs for which these cables are measured and the favorable or unfavorable influence on what we hear when said cables are connected to our equipment.

According to Audioquest:

*Audioquest diamond uses NDS system : noise dissipation system *

RJ/E Diamond prepared Cat 7 Ethernet cables use solid 100% Perfect-Surface Silver conductors, which completely eliminate strand interaction, one of the biggest sources of distortion in cables, for clearer, more dynamic and involving sound. Superior conductor metals minimize distortion by having fewer grain boundaries and less impurities (such as oxides) at those boundaries. Solid High-Density Polyethylene (PE) insulation helps maintain critical signal-pair geometry. Of course all AudioQuest Ethernet cables honor the directionality inherent in all analog and digital audio cables; arrows on the jackets indicate the direction (from source to destination) for the best audio performance.

Over the past several years there’s been a revolution in the way people store, distribute, and access digital media (in real time), including photos, movies, and, of course, music. No longer dependent on physical media, our media is often data that’s moved from multiple devices to multiple locations. For audio applications and protocols, audio over Ethernet offers the virtues of high-speed, low time delay (latency), significant distance capability (328 feet without an active booster or repeater), and extremely low-jitter, bit-perfect communication. Who wouldn’t want all of these things?

#### Solid Perfect-Surface Silver (PSS) Conductors

Perfect-Surface Technology applied to extreme-purity silver provides unprecedented clarity and dynamic contrast. Perfect-Surface Silver (PSS) is AudioQuest’s highest-quality metal. Solid conductors prevent strand interaction, a major source of cable distortion. Extremely high-purity Perfect-Surface Silver minimizes distortion caused by the grain boundaries that exist within any metal conductor, nearly eliminating harshness and greatly increasing clarity compared to OFHC, OCC, 8N and other coppers.

#### High-Speed Data Capacity

The Cat 7 cable standard has been created to allow 10-Gigabit Ethernet over 100 m of copper cabling.

#### Dielectric-Bias System With Radio Frequency Trap

All insulation between two or more conductors is also a dielectric whose properties will affect the integrity of the signal. When the dielectric is unbiased, dielectric-involvement (absorption and non-linear release of energy) causes different amounts of time delay (phase shift) for different frequencies and energy levels, which is a real problem for very time-sensitive multi-octave audio. The inclusion of an RF Trap (developed for AudioQuest’s Niagara Series of power products), ensures that radio frequency noise will not be induced into the signal conductors from the DBS field elements. (DBS, US Pat #s 7,126,055 & 7,872,195 B1)

#### Carbon-Based 3-Layer Noise-Dissipation System (NDS)

It’s easy to accomplish 100% shield coverage. Preventing captured Radio Frequency Interference (RFI) from modulating the equipment’s ground reference requires AQ’s Noise-Dissipation System (NDS). Traditional shield systems typically absorb and then drain noise/RF energy to component ground, modulating and distorting the critical “reference” ground plane, which in turn causes a distortion of the signal. NDS’s alternating layers of metal and carbon-loaded synthetics “shield the shield,” absorbing and reflecting most of this noise/RF energy before it reaches the layer attached to ground.

** Geometry Stabilizing Solid High-Density Polyethylene Insulation*
** Precision-Made Low-Loss Ultra-Wide Bandwidth Connectors With 100% Shield Coverage and Strain Relief*
** All Conductors Controlled For RF Noise Directionality*

The AudioQuest factory, now that’s impressive.

Je comprends parfaitement ce que vous dites, je ne suis pas d’accord.
No one knows what effects the Chord mini-coax streaming cables have regarding RFI & other noise artefacts, why ?? because no one has made such a study.
The same applies to more conventional ethernet cables such as those from AQ.
All this obsession & argument over ethernet good/bad, best/worse & fancy/generic is not about music or hifi, its just forum keyboard warriors stuff, get over it…

See the post above about the diamond ethernet cables scientific claims. They indeed study the noise reduction process in ethernet cables.

You are probably more a keyboard warrior than me. Compare the numbers of the words you have typed here vs mine…since the beginning of this thread.
