jelt2359 Posted June 6, 2017 Share Posted June 6, 2017 I'm thinking of using this in conjunction with a mutec, then using mutec wck out to my rednet 3. Does that sound like a good idea, or should I only use this with the mutec? Still not sure what are the differences of wck in (on rednet) vs what the mutec has. Link to comment

And I would like to know if Ref10 able to connect to sMS-200Ultra with master clock that has 6-9v connector Yes, I would also be very interested in this. It might be useful if we had some kind of summary as to the basic uses, benefits and compatibility of the REF10. From my perspective, I am a huge advocate of the Mutec MC3+USB. The Mutec is by far the best 900 Euro's I have spent on audio kit in a long time. Then we get the the 'add on' REF 10. Now, the idea of adding something to the Mutec that improves performance is highly compelling, that is until you realise that the 'add on' is over three times the cost of the original MC3+USB. So a struggle a bit psychologically with this. OK, high quality clocks are expensive, I get this. It is just that somehow I feel that if I'm buying a 3600 Euro product I need to do more with it than connect to a 1000 Euro reclocker. Maybe the MC3+ REF 10 would provide excellent results well worth the extra cash, I do not know, but it is in part a psychological consideration. Somehow for me if I was connecting say a £3K clock to a £3K dCS Network Bridge, this would seem reasonable, but a £3K clock to a £900 USB to AES/EBU converter I do struggle with! (Although as posted earlier, it would appear that the REF 10 is not compatible with dCS products, which is a shame) On other threads there have been reports of folks getting good results using the SOtM clock board to run Ethernet switches, endpoints, USB regen type products. Is there any potential to use the REF 10 in a similar way? For me, I could well imagine a set up with the REF 10 connected to my Ethernet switch, a sMS-200Ultra and the Mutec. Is this sensible from a sound quality / performance perspective, would it even work? It is perhaps worth mentioning that I bought the Mutec MC3+USB as a 'bit of a punt', mindful that I could order with a 30 day return policy. However, when you get to the £3K + price point, 'taking a punt' seams a little reckless! So I guess another question is will the REF 10 be available for demo in the UK, or will it be available similar to the MC3+USB, purchase with a 30 day return policy?

The MC3+USB have a 10MHz input and that will the SMS 200 Ultra also have if you get the external clock option (inside the Ultra is a sCLK-EX board that will use the 10MHz for referens to it`s output what that now is? ) https://www.sotm-audio.com/sotmwp/english/portfolio-item/sclk-ex/ If you want to use a external clock for your switch for example you will need to find the clock on the circuitboard and se what MHz that runs and then get a sCLK-EX board with the right output and then connect the REF10 to that. The 10MHz clock is just a referens to the other clocks if I get this right. The manual shows example of how to use the sCLK-EX and how to connect it to a 10MHz master clock. https://www.docs.sotm-audio.com/lib/exe/fetch.php?media=manuals:sclk-ex_operating_instructions_rev1.6_-_en.pdf julian.david and Confused 2 Main system TAD D1000mk2, TAD M2500mk2, TAD CE-1, Ansuz Mainz 8 C2, Ansuz Darkz D-TC, Qobuz Studio -> Roon ROCK on NUC -> Uptone etherREGEN -> dCS Network Bridge -> AES/EBU -> DAC HD Plex 200W PSU (4 rail for ISP fiber, router, etherREGEN and NUC) Second system Qobuz Studio -> Devialet Silver Phantom, Devialet Tree Link to comment

If the sMS-200Ultra is simply a sMS-200 with a better clock, then I would have thought a sMS-200 (not Ultra) with the external clock mod would be all you need? The short answer is, it's complicated. Clocks have to be placed as close to the DAC as possible. This is because the jitter performance suffers the more interfaces get in the way. If you had clocks with equal performance, the clock placed next to the DAC will perform better than the same clock placed externally. Furthermore, the performance of the external clock depends on the type of PLL (phase lock loop) in your DAC. Using an external clock may or may not increase the performance of your DAC. It comes down to the performance of the external clock, the performance of the clock in your DAC, the design of the PLL, the number of interfaces the external clock has to traverse, and even the quality of the cable connecting the external clock to your DAC*. (* this is something that even objectivists won't disagree with! It needs to be 75 Ohm impedance, and both clock output and DAC clock input need to be designed within spec, otherwise jitter performance suffers) PaulJL 1 Link to comment

To make sure I understand this correctly, if you had a system with say a REF 10 clock, feeding both an sMS-200Ultra 'end point' as well as a Mutec MC3+USB, to optimise you would need to make sure all cabling and connections are per the 75 Ohm spec, plus it would be important to keep these cables as short as is practically possible, in particular to the Mutec MC3+USB?

Keith_W Posted June 7, 2017 Share Posted June 7, 2017 What I am saying is that the clock signal generator has to be as close to the DAC chip as possible. This is why the clock which is built into your DAC has an inherent advantage over any external clock. For an external clock to offer superior performance depends on the combination of factors that I listed. Note that I am careful to say that the external clock will or won't offer a performance advantage. It might, but it is not possible to make a blanket statement. Unless you happen to be John Swenson and have access to equipment that can measure this amount of jitter, you will not be able to tell the difference an external clock makes (either positive or negative), short of using your ears and deciding if it sounds better or not.

The 10MHz clock input on a SMS 200 Ultra is 50 ohms and the REF10 has both 50 and 75 ohms (dont really know how this works but perhaps @julian.david can explain this). I think SoTM uses a 50 ohm connector on their stuff so you would need a cable with 50 ohm SMB plug at the SMS 200 end and a 50 ohm BNC plug at the REF 10 end and of course a 50 ohm coaxcable something like a RG316 cable with smal diameter to fit the SMB plug.

Just look at the posts up this page alone. There is a prevailing view out there about this. Maybe it matters more for "word" clocks rather than "master" clocks. I don't know. That's why I'd like the experts at Mutec to weigh in. Does master clock cable length matter? Does it need to be super short - like 0.2m - for the master clock to provide any benefit at all over a good built-in reference clock like the one in the SOtM sCLK-EX board?

Yes, I too am interested in some clarity here. To be honest, I am reading stuff on other threads in this forum where folk have achieved excellent results adding various clocks in the chain before the DAC. (see the 'front end' known as 'the full Romaz') Then we have other posts providing a note of warning with respect to master clocks and some indication clock implementation may actually be detrimental to performance. Away from the purely theoretical discussions, I could easily imagine myself buying a sMS-200Ultra to feed the Mutec MC3+USB I already own. This alone should be a reasonable 'front end'. Then I would have the possibility to add the REF 10 to act as clock for both the sMS-200Ultra and the Mutec MC3+USB. The question is, would better results be achieved simply using the REF 10 to clock the MC3+USB alone, and avoiding using the Ref 10 to run the sMS-200Ultra as this would be counterproductive?

Well it seems many people are interested in this setup. I am another one. I have been recently to the Monaco Hi End and I have been impressed by the Sforzato Master clock (14.000 €) attached to the sforzato server and Dac that was confronted with another Dac (metrum adagio with no master clock). According to the Dutch distributor the master clock made the difference in performance ( the adagio is said to be an outstanding Dac) And what was that difference? Well, the master clock made the sound so much clear and clean, obvious. So now I am looking to some kind of clock to include in my setup. I have the SMS-200 and I was thinking to upgrade to Ultra. The ref10 also seems to have a reasonable price. Who is going to pull the trigger first?

Maybe master clocks are different, but I just learned from May at SOtM that in their internal listening tests, they found that SQ deteriorated between using SMB clock cables of 0.3m vs 1m. Again - this is in the context of distributing (word?) clocks of 24MHz and 225MHz from the sCLK-EX in the Ultra box to the other boxes in the chain. I'm hoping Mutec will clarify for the master clock @ 10MHz. My Audio Setup Link to comment
