That’s only relevant to synchronous digital audio transport, as in S/PDIF, I2S, or Ravenna. Normal streaming layered on TCP/IP (which RAAT is) is asynchronous, relying on buffering at the endpoint to manage timing. Of course it’s possible that an endpoint may be poorly designed so that its (re)clocking of the audio signal is sensitive to upstream processing or electrical characteristics, but if so replace your endpoint, not your network cabling.

Even for S/PDIF, there are DAC chips (e.g. ESS) that use internal buffering and PLL to reduce jitter to acceptable levels - assuming there was significant jitter in the first place on a 6ft optical/coax cable.

I love the Digital Music World - Great sound and convenient 
Do I understand all the technical things behind it - NO!
Today I installed my new Cisco Meraki Go 8 Port Switch (GS110-8-HW-EU). Solid product.
After spendning a couple of hours to get it up an running, I must say it sounds great - better than my Netgear GS 105. Why does it sound better - I don’t know, but I does.
AND: If I use my new Blue Jeans Cable Bonded Pair Cat 6 Ethernet (UTP) and connect from the Cisco switch to my router, no internet signal. If I use a cheap CAT7 cable from my Cisco switch, I do get internet signal from my router. But why is that the case? I did not have that problem with my Netgear GS105
It is a strange world

How do you connect your Linn streamer to the Cisco switch?
Blue Jeans Cable Bonded Pair Cat 6 Ethernet (UTP) from Linn to switch. But that is not the problem. From switch to router is the problem.
How do you connect your Cisco switch to the router? Did you reset your Cisco switch to the factory settings?
Right noch cheap CAT7 - and yes reset - the whole program
You can try different input socket(s) on your Cisco switch, and make sure that Reset is reset (i.e. it must remove all previous settings). Maybe your old Cisco switch does not like CAT7?
Recall what @jussi_laako said Sound quality: USB vs. Ethernet (LAN) - #46 by jussi_laako
and here Sound quality: USB vs. Ethernet (LAN) - #44 by jussi_laako
Maybe the previous owner set to the bandwidth of the input socket/port that you are using to 100 mbps, and you know that the Linn streamers (at least the latest KDSM/3 Organik) do not like low speed (<= 100 mbps).
But the reward will be big if you get everything right on your Cisco switch.

Hi! I’m newbie here. Regarding the two fiber switches you connect using the Tx or Fx port?
So two of this is from the Ethernet port to the switch port, fiber on the middle
TP-Link Gigabit SFP to RJ45 Fiber Media Converter, Fiber to Ethernet Converter 10/100/1000Mbps RJ45 Port to 1000Base-SX Multi-Mode Fiber (MC200CM) Black https://a.co/d/0K1UeVL
The concept is: “noise” travels through the metal-based interconnect cables, but not through fiber.
From your router ---------- to a switch (such as Cisco Business CBS110-5T-D Unmanaged Switch | 5 Port GE | Desktop | Ext PS | Limited Lifetime Protection (CBS110-5T-D-NA));
Out of the switch ---------- to a device that converts wired ethernet to fiber (such as TP-Link Gigabit SFP to RJ45 Fiber Media Converter, Fiber to Ethernet Converter 10/100/1000Mbps RJ45 Port to 1000Base-SX Multi-Mode Fiber (MC200CM) Black), using both the TX and RX with this: 3 Meter OM1 Multimode Duplex Fiber Optic Cable (62.5/125) - SC to SC - Orange;
This connects to an identical device that converts fiber back to wired ethernet (another TP-Link Gigabit SFP to RJ45 Fiber Media Converter) to -------------your Streamer or DAC.
Some people prefer to insert this fiber chain between the router and the switch instead. Either way, it costs less than $100US on Amazon for the convertors and fiber cable, which most find worth the risk to hear a decrease in noise and improved sound quality.
I would also recommend that you upgrade the power supply to the switch which will give you another improvement, such as are available from iFi like the iPower. Some prefer Linear Power Supplies at greater expense.
Now, you can upgrade that inexpensive Sisco switch to an “audiophile” model such as the Paul Pang Audio OCXO Quad Switch that costs over $2100US…
Just understand that you will likely require a quality stereo system that is very “resolving” in order hear any sonic differences. If your system has a high Signal to Noise Ratio to begin with, you may not be able to detect the decrease in noise coming into the system.

Many thanks for such detailed information! In my case I have 2 DAC connected to my amplifier one internal DAC-60 other external ifi NEO iDSD, both using 2 NAA with a Intona usb filter on the middle.
I was thinking using the setting to connect to a switch and from the switch to the NAA.
Any comments on below switch?
Silent Angel Bonn N8 Audio Grade Network Switch
Here my settings
One popular option is to order a fitlet2 with SFP option for use as a NAA. This allows you to go straight with optical to the NAA. No need for media converters (if your switch already has SFP ports).
With optical you need to pay a little bit of attention that the SFP module and/or media converter supports the required functionality that is 802.3x Flow Control. It is not the case for all devices.

Many thanks for suggestions! Just saw this review and seems the Rpi4 with the Intona on usb before DAC is a great choice:
But! Will definitely consider the NAA optical update 
Edit: The Intona did made difference,

Interesting – in which way did it make a difference?

I noticed subtle details on dynamics and more crispy sounds that made me feel musically it was louder 
.
I like it too because of voltage protection to my DAC, we have many thunderstorms 
here in HK, so that’s another plus.
Notice It gets a little warm but less than ifi purifier. The product was not only designed for audio, but also other applications, which makes me also trust more the quality of the product.
Edit: Also @jussi_laako suggestion for my DAC-60

‘Jitter’ is the bogeyman we’re all supposed to be afraid of.
The fact is, is that with a well-designed DAC/Streamer, it is negligible if not non-existent and all these silly refinements make crazy claims to reduce or eliminate it.
Before I upgraded to Organik I used such things with my Katalyst KDS/3. I thought that using an iFi Elite/EE 8Switch/Chord Sarum T Streaming cable combo made a difference.
Since upgrading to Organik, I can’t hear any difference whatsoever. Go figure!

Groundhog Day again. An interminable loop. This is getting so booooring.
Now we’re back to the Silent Angel, the device that was expertly debunked on another thread a few months ago. It’s cheap circuitry inside a cheap casing (had one myself, must confess, send it back). Can’t do anything because there’s nothing to it that you can’t get with a decent regular switch. Really, it’s like filling an expensive looking water bottle with tap water and then selling it for a hefty profit. Welcome to the land of the gullible.
Must be some form of viral self-hypnosis. Doesn’t happen in any other media domain. Weird. Just weird.

I’m personally not into “audiophile switches”. I just fail to see the point. And for me, they are functionally lacking. So I’m just sticking to Cisco and HPE/Aruba smart switches and wireless access points (PoE powered corporate style clean white box), although I do have a couple of small HPE unmanaged switches too.

Well nice for you to go the Organik route. Though for most users that spend that much money on their setup it’s about what tweaks provide the best price / performance ratio.
An EtherRegen is a useful tool as are power supplies, reclockers etc.
