SOtM sNH-10G Network Switches x2 : The NEW KING of USB/Network Gadget Setup

I wrote a thread about 3 months ago : The Best USB/Network Gadget Setup I have auditioned in 2018 : SOtM+Cybershaft+Uptone.
https://www.whatsbestforum.com/thre...itioned-in-2018-sotm-cybershaft-uptone.27025/

It has been surpassed in just 3 months' time!
I listened to the following setup last night :


20190328_214455_2.jpg

Most of the components used are the same : Cybershaft Limited2 OP20 10M clock, SOtM tx-USBultra usb conditioner, Habst 5N Silver Cryo clock cables & coaxial digital cables; Lessloss C-Marc Supercord with Firewall 64X module, Chord Blu2 for upscaling before entering a Chord DAVE dac ...etc
Please refer to my previous post.

The only difference was that TWO SOtM sNH-10G Network Switches were used.
These audiophile switches have got SFP sockets for optical transceivers.
So they were linked up in-series by a single-mode optical cable.
20190328_214706_2.jpg

The Cybershaft Limited OP20 has three 10M clock outputs so the two SOtM switches and one SOtM tx-USBultra were clocked/syned by it.

The effect is phenomenal!
Once we have heard the dual-switches config, nobody are willing to go back to single-switch config!

The sonic improvement was in every aspects but most importantly the background quietness.
Suddenly much much more could be heard and the sound becomes so natural.

I am not a tech guy but I speculate that the optical connection has isolated most if not all of the noise coming from the CAS components & home network.

The two SOtM switches and the tx-USBultra clocked/syned by the extremely accurate Cybershaft 10M clock may be acting as reclockers.
An analogy may be the tweak of cascading/stacking multiple Mutec MC3+ together (https://www.mutec-net.com/artikel.php?id=1388254422).

My friends and I also did the following comparison : One SOtM switch+Cybershaft Clock vs Two SOtM switches (no Cybershaft Clock).
We found that the latter performed better! The sound was more natural.

If I can get hold of more SOtM sNH-10G Switches, I will try using three or four of them together for sure!
But of course I expect the Law of Diminishing Returns will kick in.

Anyway I am confident to say that this Dual-SOtM Switches is currently the best CAS network setup I have ever encountered.
 

Comments

I view the network setup as a whole system on its own and the permutations are just as endless as the main systems setup choices.

It can easily cost a rather substantial sum invested to a top class network system that one has to decide when it is enough and be very satisfied.

Very true. The benefits I had were for both my 2-channel audio system and my SS HT system, so it was a double-win.

In my experience, yes.

What SFP module did you use ? Has anyone played with different optical cables ? Has anyone tried a SFP direct attach cable ?

Not using optical. Good ol' CAT6.

"I am not a tech guy but I speculate that the optical connection has isolated most if not all of the noise coming from the CAS components & home network. "

To do this requires using a SFP module that was purchased separately.. I dont think optical cable brand changes will make any difference as its just to the WAN ( internet ) side. But I need to know what SFP modules work in the SOtM switch as isolation will make a big difference no doubt

SFP port devices can vary with which SFP modules they like, so I am just checking..

No need for Gigafoil. Just get the SOTM switch with the clock input, and connect that in your MSB clock output.

[QUOTE = "asiufy, post: 570309, membro: 1550"] Non c'è bisogno di Gigafoil. Basta inserire lo switch SOTM con l'ingresso dell'ora e collegarlo all'uscita dell'orologio MSB. [/ CITAZIONE]

impossibile

L'output word sync è un clock a 44,1 kHz o a 48 kHz. I dispositivi SOtM richiedono un orologio da 10 MHz.
 
So if the gigafoil and a good psu just prior to MSB renderer are providing a pure digital feed, what would the sotm switch be doing to make it sound better?
None of these things are totally immune to jitter, so feeding with a low-jitter signal is better than a high-jitter signal, even the SOtM switch.

OK then. My ears are wrong, and the amazing improvement me and my friends are experiencing is all in our minds.

And this from the MSB Diamond DAC V Manual

Clock Interface
After years of experimenting with inputting and outputting clocks we now strongly recommend not doing this. A low jitter clock must be physically close to the DACs. There is no lower jitter clock than the MSB clocks, and even if there were, once the clock was transmitted from an external box so much jitter would be introduced in the cable that the clock would be marginal at best. So we are confident that no benefit would be gained from an external clock.
A different set of problems exist with outputting clocks. A paradox is created as a source needs a clock to transmit data, but when the DAC sees the data, which can be at any sample rate, it adjusts the clock to match. No source can handle its clock adjusted on the fly. Only the MSB Transports can handle this as the PRO I2S interface is smart and negotiates the proper clock to be sent back to the transport. But, if you do have a need to access this clock, it can be done.
Within the MSB Network connection is a clock interface that allows multiple Platinum products to be synchronized, allows the Plati- num Clock to be input or output. The interface is a LVDS format clock interface with a signal level of 250 mV pp.
Pin Identification - The pins shown in the figure below are identified as follows: 1. M Clock + (Positive side of balanced Master Clock)
2. M Clock - (Negative side of balanced Master Clock)
Clock Frequencies - The clock can be selected to be either an input, output or turned off in the setup menu. The output frequencies are as follows:
· 44.1, 88.2 or 176.4 kHz sampling frequency source outputs or inputs a clock frequency of 22.5792 MHz · 48, 96 or 192 kHz sampling frequency source outputs or inputs a clock frequency of 24.576 MHz.

Modern MSB DACs, which the V isn't one of them, has a clock OUTPUT. That's what's connected to the clock INPUT of the SoTM switch.
What you quoted has absolutely nothing to do with the current environment being discussed.

What is the frequency of this clock output?

If I wanted to try to go fiber between my Ethernet switch and Music server, can someone suggest the
Fiber Type, SFP Type and PCIE card to buy for best results? IM looking for model numbers if someone has played with this and has a preference.


My switch is 1GE SFP port.

Thanks

Have you tried not connecting the clock cable to SOTM switch and hear the same improvements? The clock input in SOTM IS 10Mhz. I don’t think MSB clock can generate 10 MHz. They are incompatible. One should be using Mutec Ref 10 or CH Precision T1. What you hear the improvement is simply the cleaning of signals by SOTM switch.
