ETHERNET CABLES

Ethernet cables do not make sonic differences

If only that were true, life would be grand. 

I second the fiber media converter tactic.  It makes a world of difference in the sound. 

I too work with computers and in fact, I work with highly complicated global networking.

Guess what? Cables absolutely matter and the correct cable for the correct application is critical.

I echo the comments about sticking with Cat6 - I have used Audioquest Pearl Cat6a and the results were very good.

For a cable run that long you should consider the recommendation around a fibre run however the claimed isolation benefits are reduced as the 10GTek devices are very noisy, especially their cheap-as-chips SMPS (I've trialled a pair of 10GTek's and they aren't great, very cheaply built). Alternatively, look at using Powerline Ethernet Adapters with passthrough sockets - they can yield great results. TP-Link adapters are very well made.

If you want to get into fibre in a quality way consider using Cisco switches with Cisco SFPs as they have very high-quality internal power supplies for serious data and voice applications and are intrinsically less noisy.

With all of this said, my sound quality improved the most when I switched to using a wireless network bridge (ifi Zen Stream) with a quality WiFi circuit connected to a high-quality WiFi router (TP-Link Deco). For me, this is the cleanest (less cabling mess) and sonically best solution.

REVIEW:What causes audible differences in network cables

https://alpha-audio.net/review/wat-zorg ... erkkabels/

Intro

We round off our little investigation into network cables with a listening test and a clear conclusion. As promised we subjected the network plugs to a listening test and listened to three different configurations: shielding fixed on one side, shielding fixed on two sides and double shielded (and both sides connected). Do we hear differences? Well…. yes…!

Let’s clear up one myth: there is NO audible difference in network plugs. There is a difference in build quality, price and ease of installation. In short: it does make sense to invest in a good plug.

But let’s continue with the sound reproduction: as you know, we have installed everything from standard plugs to expensive Telegärtners. We tried all cables on the same switch (with an IFI power supply) and listened to the same system:
We did not notice any difference between the connectors. Sometimes we thought we heard something (think of a louder or sharper S-sound), but when we went back to the other connector, there was no difference. It is sometimes very complex to listen to this properly and to judge it honestly. But after hours of switching back and forth, we dare say that there is no difference in reproduction. In any case, we do not dare to take a bet in a blind test…

But where we do hear immediate differences – and continue to hear differences even when going back and forth – is the method of shielding.

We made three cables for this purpose: one cable with DeLock plugs and shielding fixed at one end. One cable with Delock plugs with the shielding fixed at both ends and finally the double shielded version with the nice sleeve. Also with the shielding on both sides (and Delock plugs).

What we observe almost immediately is that the version with the shielding fixed on both sides focuses better. The version with shielding on one side seems to play a bit larger, but that is not true: the effects in the song Perfect Life by Steven wilson are placed at the same spot in the room, but are more tightly framed with the cable where the shielding is fixed on both sides.

With voices, the same is true: it’s tighter in focus and also more stable between the speakers (if we move our heads back and forth, the voice stays in place better very odd).

Going to the double shielding we make another step. Again a bit more tightly focused, again a bit better framed. And with that a bit more calmness in the reproduction allowing details to surface a bit easier.

Clearly, for us it is clear where the differences come from: shielding, shielding, shielding.

And that is quite logical if you consider that a network cable is included in a digital chain. A chain that relies on clean energy to keep everything clocked tight. A chain that works with noise-levels of -140dB. A chain where small deviations are immediately audible in staging, focus and smoothness.

This also explains why fiber networks work so well as a first upgrade: you immediately shut out a lot of misery by creating a barrier through which electrical energy cannot pass. And thus no electrical noise (common mode in particular).

To conclude…

Can you hear differences between network cables? Yes… definitely. Our samples have shown that. And about the real cables you can buy at the store… pay particular attention to what the manufacturer has done in terms of shielding. We would still leave the unshielded versions. Especially after this experience. But anyway: try it yourself at home!
