SOtM sNH-10G - SOtM’s first network switch

[PrTv]

Hi guys, I have a question about the standard and upgraded versions of this Switch.

Earlier this month, I borrowed the standard Switch + standard PSU from a local distributor to try, and after hearing a clear improvement, I ordered the fully upgraded versions (Switch + PSU), and based on the boxes the specs are as follows:
- PSU: Silver DC Cable / SE-S / CAP / eABC
- Switch: sCLK-EX / 12V / MC75 / SE-S / EVOX / eABS

I received them earlier last week and when I replaced them with the loaner (standard), I was surprised that this upgraded version sounds brighter / harsher and not as full-bodied as the standard version.

 

 

I stacked them and compared both with the same AC + LAN cables and the difference was very clear.

Units with gold badges are loaner (standard version) and units with silver badges are mine (upgraded).

I truly have no idea what might have caused this and below are my observation:

- Is it because of the voltage? The standard version uses 9V but mine uses 12V. I understand that if the external clock is installed, 12V is required... is this correct? Would voltage affect how the unit sound? What will happen if I reduce my voltage setting behind the PSU from 12V to 9V?

- Now mine have around 70-75 hours on them (both PSU and Switch) but still sound brighter than the loaner (that has countless hours on... possible thousands). How long would it take for the Switch / PSU to fully burn in?

- Is it possible that all the silver upgrades/components inside the black unit cause it to be bright?

Any suggestions or tips / settings I might try to make it sound more full would be appreciated!

FYI, I made sure to recheck the voltage setting of the PSU and both units were setup correctly (standard version with 9V and upgraded with 12V).

Thanks!

Hello @PrTv i'm afraid i don't have clear feedbacks to share with you except that my first assumption was more on the burning time side : you need perhaps more than 70 hours. Silver is reputed to bring more bright sound but harsh not sure. Yoou don't have any opportunity to try another 12V PSU different than the upgraded one you ordered in order to evaluate if it could come from this PSU ? I understand you can not put the one you loaned as it is a 9V.

 

In fact, i'm very interested in your feedback as i was looking to the same full option switch you selected ( sCLK-EX / 12V / MC75 / SE-S / EVOX / eABS) with priority to sCLK-EX and MC input. Do you confirm that if i want the MC input, the 12V option is mandatory ? I also understood that SoTM is recommended the 50ohm and not the 75ohm : with which 10Mhz clock are you using the sNH-10G ?

 

 

The loaner PSU can also be adjusted to 12V and I tried to use it with my (black) unit. I don't think the brightness was reduced with the standard PSU (at 12V). To clarify, I do not use the MC port at all. It just comes pre-config with the unit I purchase (one that local distributor in my country had in stock).

 

My switch has internal clock upgrade and the 75ohm clock input will never be used as I don't have external clock device.

 

I understand that inside the switch the voltage can be changed, but I don't know if 12V is mandatory with the upgraded clock board.
