Yes, all those kind of TCP/IP events happen on a regular basis. But TCP/IP deals with them even on the cheapest network equipment. Out of order packets cannot be fixed by an intermediate router, only at the destination (the packets are cached at the destination, so most events can be handled transparently). Also, a typical path from Tidal.com may go through 14 hops (14 different switches on the Internet) and it is not necessary that they all follow the same path, as the final destination device (streamer, etc) can put them back in order or request a retransmission of any packets that are missing.I installed Wireshark and did a bit of packet capture, and this screenshot alone shows the complexity of TCP/IP communication, with a bunch of different types of errors (such as duplicate and out-of-order packets) that have to be dealt with.

So far, with the Optibox. It's interesting to discover which equipment is affected by it more, and which less.
The components came in, it worked out immediately, and with no fuss:
- 10Gtek [Mini Size] Gigabit Ethernet Media Converter with MMF Module (Amazon link, $22.49) x 2
- OM3 fiber patch cable (Amazon link, $8.99) (I'm sure OM2 would be fine too)
So the current setup is:
[router] > [generic, long lan cable] > [MC] > [fiber cable] > [MC] > ["good", short lan cable] > [Bartok]
And the MCs are using just their stock power supplies.
After a couple hours of listening and couple quick direct comparisons with vs. without the MC's, I'm super-impressed. The main word that comes to mind is "natural". It's more free-flowing, "ease-ful" and relaxed. Cleaner bass. And a greater, easier conveyance of low-level information -- more sustain, more microdetails, smoother treble. No changes in tonality.
I feel like the 8Switch (in my system at least) was committing sins of omission, subtracting stuff in order to create a sense of greater separation and a blacker background. But this is not like that, and nor is it committing sins of commission either. Just revealing more of what's already there.

Next LPS on your FMC. Jameco Reliapro should do the trick.
Edit: Got also a 10Gtek FMC and since its 5V, I used a Topping P50 for both of them..

Thanks for letting us know Amos, that feedback confirms our internal tests as well. Enjoy!

Its interesting that it has that kind of effect with such a short run.The components came in, it worked out immediately, and with no fuss:

What do you think is happening that its affecting the sound in such a way?
I'm not doubting that theres a difference, I'm just curious as to what might be going on.

It's probably perfect isolation whereas before the RJ45 was probably letting in some noise spectrum.
Agreed.
And in my case, outside of "super-serious critical listening" sessions, I have my TV/gaming PC running and hardwired to the local network, which probably consumes like 100+ watts while idle, creating extra havok...

I intend to proceed with an optical system, to replace a 50ft generic CAT8 cable and LAN Isolator. I have decided on Corning fiber cable and Finisar SFP, but there are a few FMC's to choose from, at radically different prices; TP-Link MC220L, ADOT MC-1, Sonore OpticalModule Deluxe. Does anyone know how much the FMC affects the sound of a fiber network? It would seem to me that the power supply of the FMC would be the main criterion.

There's this one that @kumar402 recently posted. I havent seen any other high end option.
Has option for oxco clock.
Looks really nice, r core transformer but everything is pretty tightly packed.
I did reach out to them for R-Core transformer and the person who replied to me back is not the technical person but he got some info from his designer or technicican and replied below
" R-core transformer sound quality and noise is lower than toroidal transformer and EI transformer.
Encapsulated toroidal transformer can fix interference problem, as good as R-core.
EMI from motors, high power and current devices, cell phone…transformer can receive EMI interference
EMI filter can fix most problem, TeraDak and Metro have EMI filter too."
As far as subjective thing goes, I have kept TeraDak close to Metrum Ambre which has 30 VA toroidal transformer, and I don't hear any brightness or hum either from output of the amp or from the streamer or TeraDak. no Saturation of any transformer is going on to cause audible hum etc.
Also, my tubes are prone to EMI /RFI etc and there is no buzz or hum picked up by them and I am talking about using as sensitive tube as it can get.

Unless the power wires and the Ethernet wires are running parrallel AND right next to eachother, I would not worry about it. It sounds like they are indifferent cable tubes, so probably not a problem.
But even when EMF, etc interferes with the Ethernet wire, the result would be an unreliable TCP/IP connection, and probably not any noise carried on the wire itself getting into the music. If an abnormal number TCP/IP errors occurred at the receiving end, that could cause the streamer, etc to work harder to fix the TCP/IP error, causing some noise in the signal.
If you know the IP address (or hostname) of your streamer, go to a PC on the network and type in the following on the Windows PowerShell command line:
Code:
ping ifi.local
Code:
ping 192.168.1.70If you don't ever get any errors with the ping command, then I would not worry about it.

Do I need 2 P50? Or can I use one connected to both, what power cable could I use to split the power? If it’s possible
