Personally, I have 2 Sotm snh-10G with clock inputs, synchronized with a LHY OCK-2S clock.
The addition of the first was significant, the second was just incredible.
The soundstage has expanded so much, the details are endless.
I think there are two prerequisites in Hifi streaming, the first a quality AC current (good wall sockets and quality power cables), the second an audiophile switch… Of course, it’s always 0s and 1s that arrive in the streamer, and yes the song is always the same, but…, what changes with these improvements is the perception, the immersion in the music, the fact that the speakers disappear to make way for the music.
The contribution of fiber is an undeniable plus, more silence, more of everything…

You keep mixing the terms…One is galvanic isolation, the other is isolation through optical fiber. If you want to make an isolation through the optical fiber before the switch, you can use one in a box solutions (iFi Audio LAN iPurifier Pro, Ediscreation fiber-box, JCAT OPT Bridge, Reiki Optical Decupler, etc.), or the ADOT solution (Audiophile Digital Optical Technology) which can be done with equivalent equipment.
Galvanic isolation in the network can be done with equipment such as Baaske-Medical MED MI 1005 Network Isolator, Emosafe EN-1005, Aardvark In Line Network Filter, JCAT Network Isolator, etc., which is something else (see image).

I use this type of fiber isolation: iFi Audio LAN iPurifier Pro, with a good ifi Ipower MK2 power supply, it gives very good results, for a “reasonable” price. it is connected to the output of my internet provider’s router and is connected (on both sides) by Sablon ethernet cables. the output of the filter goes to the 1st Sotm.

Hi PatriceP,
I also use the iFi Audio LAN iPurifier Pro between the Internet provider’s ONT and the router. Initially I also used an SMTP power supply, Ipower MK2, but then I replaced it with an LPS, Topping P50 (also sold by Cybershaft under the code CYB-LN02).
For the linear source, I use a decent 220V current cable and a good USB cable.
However, the electrical/optical and then optical/electrical conversion is not totally free of electrical noise and is dependent on the quality of FMC, SFP, FO used.
As they say that a picture is worth 1000 words, I give only an example from the FMC field (above Sonore opticalModule 395 USD and below TrendNet FMC 46.99 USD).
Similarly, the discussion can continue regarding SFPs (laser type) and FO (plastic or glass).

Hello Philsisch,
There is a media converter inside the RS130 that converts the optical signal into an electrical signal! You can connect RS130 via optical fiber (FO) and SFP to a switch that has an optical port.
The SFP and FO model you have chosen are multi-mode which, according to general acceptance, are inferior to single-mode.
For what reasons did you choose a router instead of a switch?
I use a supercapacitor jack filter between the Ipower and the Ifi lan filter, it’s like the filter is connected to a battery…

Hello,
Thank you very much for your response and the helpful insights.
However, I believe there is a slight misunderstanding: I’m already using the RS130 via SFP and fiber-optic cable. Currently, I’m utilizing a low-cost TP-Link Gigabit SFP Media Converter after my router to establish the SFP connection.
Thank you as well for pointing out the potential benefits of Single-Mode SFP modules. I chose the Allied Telesis Multi-Mode module based on a friend’s recommendation and its compatibility with my setup. Additionally, I specifically wanted a product that is not manufactured in China. As far as I know, the Allied module is made in Japan and is said to be of exceptional quality.
Do you happen to have any recommendations for an SFP module that offers a good price-performance ratio, is of high quality, and also not made in China?
Regarding the switch: I deliberately decided to minimize the amount of equipment in the signal chain. That’s why I opted for a new router with an SFP interface, as its clocking appears to be sufficient for my needs according to the specifications.
Thanks again for your support!
Best regards,
Philipp
Isolation through fiber optic is a form of galvanic Isolation. What do you think galvanic Isolation is? It seems you don’t understand the meaning of the term, yet you claim I am confusing the terms?
fiber optic cable can be used for galvanic isolation because it transmits signals using light instead of electrical current, effectively creating a complete electrical separation between two circuits connected by the fiber, thus achieving galvanic isolation. You just reading audiophile product marketing of what galvanic isolation is, but you can consider to think about it from a scientific perspective with deeper conceptual thinking. Of course we all don’t know everything, but we shouldn’t accuse people with faulty ideas.
I think that the FMC (fiber media converter) TP-Link is entry level and there are cheaper (industrial) or more expensive (audiophile) options.
I would recommend the TrendNet TFC-1000MGA . But then I don’t understand why you don’t directly connect RS130 to the router if it has an SFP port!
Which eliminates the need for an FMC! (RS130>SFP>FO>SFP>router)
Regarding the SFP modules (as long as they are original), the place where they are manufactured is the last thing to worry about.
There are other criteria by which you have to choose them. As you can see, HiFi Rose uses SFP modules and single-mode optical fiber both for the connection with RSA720 and RD160.
The most important are the SFP modules, and the type of laser used in them.The most commonly used are, FP (Fabry Perot Laser), VCSEL (Vertical-Cavity Surface-Emitting Laser), DFB (Distributed Feedback Laser) also known as DML (Directly Modulated Lasers), and EML (Electro-absorption Modulated Lasers).

I contacted Alvin a while back, and his statement was, that they do not manufacture the LHY-10 any more.
LHY said that new model replacing SW10 is coming.
Do you know what features will be different?
Don’t remember what the boss said. Except that it will be an upgraded model with more features.

I wrote again to Alvin, see what’s his statement on this.
With a SW-10 I could realise my LAN with just 1 device next to my setup. otherwise I would have to go with a SW-6 and keep my SW-8.

Answer recieved today - No SW-10 or replaced model!
@TomT maybe you can enlighten us with your information from LHY?
As I replied to Bicyle earlier: I don’t remember what the boss said. Except that it will be an upgraded model with more features.
FMC will be integrated to the new model, something like that. I am not sure
I have the etherregen . External clock and sfp connection. I am very happy with the sq
Hello @SPaul,
what do you think of this combination? Would this be the better choice?
Router:
-
MikroTik RB4011iGS+5HacQ2HnD-IN
- High-performance router with an SFP/SFP+ port, 10x Gigabit LAN, and dual-band WiFi
SFP Module:
-
Finisar FTLF1318P3BTL
- Single-mode SFP module, 1000Base-LX, 1310 nm
Best regards,
Philipp
