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.

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

"SOtM recommend the TP-Link TL-SM311LS Gigabit SFP module. "

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.

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.

I think a lot of the benefit of the SOTM ethernet, or gigafoil, etc has to do with reducing the electrical noise coming into the dac, vs jitter.
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.

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.
