I see…The supplier does the sorting and grading, thanks !
I Can see that you use the output directly, so no need for an extra level adjustment to use with the RS130 ?
BTW, you didn’t report your experience with the RS130 and this external clock…
I understand that @ROSEHAN suggested SineWave only but why. If I own high quality BNC cables shouldn’t the RS130 be capable of both Sine and Square Wave without issue as long as the Master clock can accommodate both. What is the technical limitation that HifiRose is only suggesting SiineWave for the RS130, that is my question.
@duffer5 it’s a good question actually ! I will borrow a LHY OCK2 soon and check both sine & square waves…
RS130 is capable of both Sine and Square Wave
I said it rudely above.
When connecting an external clock to RS130, both sine and square waves can be connected, but sine wave is recommended.
I have MSB premier dac which has wordlock output. I’ve tried several times to sync clock with rs130 but can’t not. Unfortunately, my dac has coaxial input only (and a ethernet - renderer module) so the sound from rs130 to msb dac via coaxial without clock sync doesn’t attract me so much. Does anyone try to use msb dac clock with rs130 successfully? Tks
Using Gustard C18 master clock into RS130 via 50 ohm square wave connection with good results.
On good recordings the leading edges of notes, space and depth are superior to onboard clock to my ears. The midrange also seems more transparent highlighting more detail. The downside on poorer recordings it shows warts and all. The joy is with a button flick I can return to onboard clock or for a warmer presentation flick to the USB output and let the DAC to its asynchronous role bypassing both clocks. The joy of choice

I have both MSB DAC and RS130 streamer : MSB Word clock frequency is 22,579 MHz for 44.1KHz (or its multiples) signals, or 24,576 MHz for 48KHz (or its multiples) signals… Cannot be input to the RS130, which requires a 10 MHz external clock ! I use a Cybershaft on my RS130, which improves layer separation, attaks and mostly decays. My 2 cents.
Thank you so much. I wonder if it can be adjust by later firmware version or it is hardware matter.
It is hardware… No 10 MHz is generated by MSB DACs, but you may want to use an 10MHz external clock on the RS130.
Beyond the basic coaxial input and the already pretty good renderer (if you are ready to use Roon…), you should try MSB USB input modules, especially the fiber PROISL combo…
Yes I’m using msb renderer module. I’m curious how good it is due to budget/performance for investment option:
1- rs130 coxial and ext clock to msb
2- rs130 + msb usb module
3- msb usb module + roon nuc.
Off course add rs130 on opt 2 is probably the best but how much it better than opt 1 as I still have some doubt about usb connection as it mostly bypass many high quality components a good streamer is equipped
I use LHY OCXO EXTERNAL CLOCK TO CONNECT TO SWITCH / DAC / DDC. SOUND IMPROVEMENT CAN BE RELISED CLEARLY.
I USE HOLO RED AS STREAM TO CONNECT WITH DDC GUSTARD U18.
I CAN SAY THAT USING EXTERNAL MASTER CLOCK OXCO WILL MAKE SENSE. BY THE WAY, I CAN NOT REALISE SOUND IMPROVEMENT WHEN USING 2 SWITCH TO BE CONNECTED BY SFP PORT.

Hi ZABOKS,
What’s the impression you had with LHY OCK-2 ? Do you think it worths adding to the system?
Hi,
Which cable do you use ? 50 ohm or 75 ohm ? square wave or sine wave ?
Hi, i’m using a Cybershaft OP19A (sine wave), connected with a 1.5m 75 Ohm Cybershaft silver cable. It adds extra layering and improves note attaks.
I’m not sure ock-2 clock specs are so much better than the INTERNAL OCXO, so I cannot predict its effets…
Noted and thank you for the information.
I can add that i’m using LHY SW6-SFP Switch (connected with Fiber to my RS130) which has probably the SAME INTERNAL OCXO than the OCK-2.
I also noticed some improvement by connecting its external clock input to my CYBERSHAFT clock…
Thanks a lot.
In your opinion, which one provides more improvements, the OCK-2 or the SW6-SFP ?
Also, are you using the SFP module coming with the LHY siwtch ? From spec, it is a SFP+ 10G module. There are people saying that SFP+ module is not recommended.
I am interested to buy the LHY OCK-2 clock and FMC receiver.
Again, I don’t have the OCK-2, but a (better) Cybershaft.
I can tell though that the improvement due to this external clock is more important on the RS130 than on the SW6-SFP.
I’m using FINISAIR 1310 dual simplex SFP modules, as recommanded by ROSE.
Noted. Thanks very much.
