LowMidHigh: Thank you for the reminder on the Clock Distributor newly announced today.  I cannot edit my original post any longer so I'll amend it here....

 

 

Newly announced Cybershaft Platimum (single output 50-ohn or 75-ohm);
 
http://www.cybershaft.jp/a-products/ultimate1.html
 
or Cybershaft Limited2 (3 output 50-ohm or 75-ohm, selectable for each!);
 
http://www.cybershaft.jp/a-products/limited2.html
 
Can be ordered in levels OP14 up to OP20 (the higher levels are likely to be rare so best order soon!).
 
Kenji's been VERY busy and the phase noise and jitter specs on the higher end units are off the charts!

Brand new today (19-November-2018)

 

New announced (today) audiophile-grade Clock Distributor (up to 3 outputs);

http://www.cybershaft.jp/a-products/clockdist01.html

 

Thanks for reporting your feedback and conversations regarding the earlier generation units. I'm very glad you found the REF10

to be a perfect match for your existing gear.

 

A few thoughts based upon your post;

 

- footers: I've found putting my Cybershaft clock up on Stillpoint UltraSS footers with Bases is a very good and cost-effective

solution that delivers aurally evident improvement to isolating this clock (or any other). I would imagine that EdenSound's Terracones would also be a great solution....

 

- "Used OCXO units...": agree that Cybershaft's higher end modules (including the OP21 unit I have today) are curated and deeply tested used and proven units.  When i first heard of this as I ordered several clocks to test and to eventually own, I was skeptical being the good audio-nut that I am ? and wanting 'brand new'.  Kenji explained the benefits of finding such proven units and rigorously testing them versus buy supposedly perfect new units and hoping they will stabilize and be rock solid; I was sold on this after several iterations.  Just like anything else in high precision manufacturing, every unit coming off the line is not perfect and some are much better than others over time.  For a component like an OCXO module (or Rb for that matter) I'd rather (now) have a used unit that is validated, proven and certified than a new unit where i hope all is well...

 

- Inconsistent answers: to the extent that my experience matters, I can promise you based upon that experience alone that the inconsistencies are due to language barrier.  He's been extremely reliable in my dealings with him over 2+ years and always delivers what he says he will; the finer details of the communications and the fact that he's learning English these last 2 years including I believe taking classes as of late to improve his communications take a bit of getting used to but I trust him completely for which the proof has been in actions, not in words...

 

- Testing Reliability: Again, only from my experience, diving deep into the test results, I have found them to be squared away and objective scientific measurements.  It may help that Kenji uses the following facility for all his testing;

 

http://www.cybershaft.jp/cyberqc01.html

 

http://www.cybershaft.jp/clockcal.html

 

- Levels above OP14,....I have heard that OP14/15 is sufficient and there is no audible difference for many users who also find REF10 to deliver equal or superior performance.  For my own testing with OP's below 14, OP14, OP17, OP18, OP20 and OP21 (my unit and I owned 2 others of less precision/higher phase noise along the way from Cybershaft plus an Esoteric G-0s and G-03X), I found that not all levels above OP12, 13 and 14 delivered any benefit and in 2 cases detracted from the sound using an Esoteric P-02 and D-02 as my test rack for music listening.  I found the following to be superior in sound and noticeably better at each step (OP14, OP17, OP20 and OP21 with my preference falling for the OP14, OP17 and top of the heap, the OP21 I happen to have). This included the Rb and  OCXO models from Esoteric which weighed in with much higher phase noise and lower long-term as well as short-term precision (at least to my reading of the test results including Allen Variance & Deviation).  Listening testing was done non-blind so there is possibility of placebo effect, owner bias, etc...however I did own and OP12, and OP14, OP17 and lastly the OP21 so I would say owner bias if not totally removed was limited in all fairness.

 

- No return policy: I think this may have to do ( a pure guess) that he is small vendor and has limited markup; he cannot sustain the try, try, try and maybe buy that many audiophiles sometimes do.  As far as faith in what he does, he does share a full test and certification report battery report with the buyer (did so with me 4 times) BEFORE he ships giving the buyer the right to walk away from the transaction so to me, that is another sort of faith in one's product as he builds them all from scratch at time of order so he's taking the chance that he could build something out of his own pocket that the buyer walks away from before trying.  Sounds like a very similar arrangement just without the ship, wait, return shipment, possibility of damage expense and time....

 

- For me,...I've tried 2 Esoteric clocks (owned, Rb and OCXO) and demo'ed (2, G-01 and and G1) all weighing in at much higher prices; for me, for my Esoteric stack, I simply love the sounds and musicality that comes out when it's all driven by a Cybershaft clock...

 

Very glad you have good luck with the REF10; I've now heard as of a couple months ago at a friend's place and agree that it is one hell of a great unit!

You mount a vigorous defense of Cybershaft, Mark…The passion is appreciated. And thank you for sharing all that edifying information.

 

Still, there’re a few points I’d like to raise.

 

You completely ignored my re-stocking fee offer to Kenji. I understand he might loathe to be the victim of whimsical audiophiles, but said fee would separate the wheat from the chaff and compensate Kenji for any trouble; really an insurance policy to keep both sides satisfied.  

 

You make this point:

“As far as faith in what he does, he does share a full test and certification report battery report with the buyer (did so with me 4 times) BEFORE he ships giving the buyer the right to walk away from the transaction’”

 

That wasn’t the case with me. He was going to have my paypal the fund 8 days before the unit was ready for shipping. There was no claw-back.

 

You make this point:

“Used OCXO units...": agree that Cybershaft's higher end modules (including the OP21 unit I have today) are curated and deeply tested used and proven units.  When i first heard of this as I ordered several clocks to test and to eventually own, I was skeptical being the good audio-nut that I am ? and wanting 'brand new'.  Kenji explained the benefits of finding such proven units and rigorously testing them versus buy supposedly perfect new units and hoping they will stabilize and be rock solid; I was sold on this after several iterations.  Just like anything else in high precision manufacturing, every unit coming off the line is not perfect and some are much better than others over time.  For a component like an OCXO module (or Rb for that matter) I'd rather (now) have a used unit that is validated, proven and certified than a new unit where i hope all is well...”

 

It's very interesting logic, even convincing, but going by it, we should all inspire to purchase used and “well-tested” products, especially high-precision ones. I guess most humanity disagrees. Julian would certainly beg to differ, given Mutec has opted for a new OCXO, supposedly having given it careful consideration. Personally, I don’t care either way. I could test drive the Mutec for a full refund and that was swaying enough.

 

“Inconsistent answers: to the extent that my experience matters, I can promise you based upon that experience alone that the inconsistencies are due to language barrier.  He's been extremely reliable in my dealings with him over 2+ years and always delivers what he says he will; the finer details of the communications and the fact that he's learning English these last 2 years including I believe taking classes as of late to improve his communications take a bit of getting used to but I trust him completely for which the proof has been in actions, not in words...”

 

I’ll tell what raised my hackles. In my original communication with Kenji, he explicitly said one can’t perceive the difference between OPn and OPn+1 (e.g., OP10 vs. OP11). Later on, when I made more inquires, he stated OP16 sounded better than OP15 when feeding MC3USB. So which is which? Could be a “translation” error, but it still raised a quizzical eyebrow.

BTW (to all): The web form is not always to best to get in touch with Cybershaft if you have questions.  I don't work with them and not industry-affiliated in any way so I've had the same issue.

 

You may wish to try emailing at [email protected]; has always worked well for me and 2 other guys I know that regularly chat with Kenji via email.

Good Morning LowMidHigh, apologies for the delayed reply (work and life intervened!) and more importantly thank you for the EXCELLENT discussion!!!

 

I did not think I avoided any of your topics and in the one specific item you pointed out, I thought i gave an alternative that Cybershaft was able to provide however I'll try to be more clear this time around.

 

Here goes...

 

You mount a vigorous defense of Cybershaft, Mark…The passion is appreciated. And thank you for sharing all that edifying information.

 

from me: You are welcome...I love music listening and anything that gets me to hear more realistic and nearer to the source renditions of what' son my shelf.  I do get passionate about that as home audio owner and music-nut (sometimes too much so) however what I also get passionate about are the firms, designers, cables and gear that helps me get there.  I've spent ALOT on digital front ends of varying make-ups over time for HT+2ch and then 2-ch only with even more spent on clocking.  After hearing and believing a lot of marketing hype (PPB is better than PPM and falling for the Rubidium and Cesium games, knowing nothing else about clocking for years) it did me well to read more deeply talk to various clock vendors, etc...about 3-4 years ago which ultimately led me to Cybershaft.  The price at which they deliver better music to my system makes me very happy over and above the musical experience.  That stated the REF10 appears to be in the same quality/reasonable price band.  It seems clear to me that if I had not found Cybershaft I would most probably be running a REF10 by now...

from me:  I'm with you...While I do have a used Esoteric P-02 and D-02 that I bought, they were demos from a dealer; still used but with certain advantages (broken in, price, remaining warranty). Normally I would take your side and all my other gear purchases and cables have been brand new for 30 years as an FYI.  HOWEVER, with clock modules there is (to my non-expert understanding) Variance and Deviation, also 'Drift" that can occur in a flawed quartz oscillator cut and/or OCXO assembly over the initial time from burn in through first months of 24x7x365 usage that take time to manifest.  This is the only area in which I would say it's better to have something proven to stand the test of time (pun intended!), accuracy and low phase noise that is used versus taking many weeks or even months to find out you've got a flaw on your hands and then have to prove it.  This bears up to what some extremely smart friends (i.e Advanced Degree Physics lab-rat as they call themselves) advised me unofficially told me about high-precision clocking assemblies.  ***My logic may be tragically flawed and I should have said I'm not advocating that anyone agree with me or make the same choice; it's one I am personally comfortable with and seems to be holding up for 2+ years now very well, i.e. based upon what I hear in my system.  You know the old saying,..check with me in a few years and I'll tell you how wrong I was (or right) :--) !

 

from me: Julian and MUTEC as a whole is well respected by all and as I mentioned, if I had not stumbled on Cybershaft years ago and not had great dealings as a customer with them thus far I'd bet I'd have a REF10 in my system.

from me: I'm with you there and had similar exchange mid-way with Kenji.  Here is what he meant (at least in my case);

 

 - it is impossible or at the very least improbable to hear a difference between OPn to OPn+1 as n and n+1 are each ranges of values and the actual values plus Allen Variance and Deviance may be so close together that the net effect for phase noise is literally a few femtoseconds which no one can hear as far as I know

- it is however possible (based upon direct listening) that OPn versus OPn+1 shows one HAPPENs to work better with a specific component and the two OCXO modules then also happen to be separated only by one gradation on the scale

- (my contribution): going up the scale by 1 or 2 does not necessarily always bring benefit.  I tested a number of modules inserted in a number of Cybershaft clocks over time at varying levels from OP10, OP12 on up to OP21.  As I believe I mentioned before but will emphasize now there were some OP levels that sounded quite bad even though they were n+1 or n+2 'better' than a given OPn level that had prior sounded quite good with a component. To my limited understanding, this tells me that not all OP levels are best for all gear and some may not be good matches for audio gear at all though I frankly don't know how to pose a scientific explanation for this...

 

from me: Great Conversation, thank you! Have a great holiday weekend!

Thank you for making your points enlightening, packed with information and yet clear.

I have only one correction of sort. I enterd the cloak "fray" quite recently, when a substantial body of knowledge had already been accumulated and  disseminated. As far as I've gathered, "drift" - - that is, a clock losing its  calibration over a long period of time - - has no bearing on audio applications, which hardly ever extend longer than 2 hours.

In fact, what's crucial during that the relatively short period of playback is to consistency deliver high-precision signal, which OCOX  oscillators true shine at. 

 

In summation, even an aging clock that has drifted far off should deliver the same sonic benefits as a brand-new one.

You are welcome...it's a great discussion and I appreciate the candor and all the useful facts!

 

I have the same understanding of drift at a baseline level however if a clock drifts in terms of its short-term accuracy and therefore also affecting phase noise (being then possible higher), I had thought (and could be wrong) that that would affect the quality of the sound.

 

It is definitely true as you state it though to my understanding, i.e. if a clock's behavior during playback periods is to produce rock solid and accurate timing, all will be well and what you state is 100% on point.

 

Have a great day!

Hello all,

 

although the last reply has been sent some time ago in this forum, I hope somebody will be able to help me here.

My name ist Olaf and I just signed up today because I have an issue with my brand new (second hand) Mutec MC3 USB that will be delivered next week.

 

I am not very familiar with Ohm, Volt, Ampere, SPDIF, etc.

 

For me it was difficult to figure out how to connect an Mutec MC3 USB to my headphone system.

 

Meanwhile I think I will connect my Auralic G1 > USB > Mytek Brooklyn Dac+ > USB > Mutec > AES/EBU > Mytek Brookly Dac+

Am I right? 

 

Now it gets even more difficult for me. I also have a Cybershaft OP13 Clock. 

Cybershaft (50 Ohm) > 50 Ohm Cable > Mutec Clock in (75Ohm). Can i do this or do I need an adapter. (Like the one that Cybershaft offers??)

Mutec Clock Out to my DAC (Mytek which I believe has 75 Ohm hopefully)

Mutec Clock Out (75 Ohm) to my SOTM USB Ultra (50 Ohm) Can I do this or do I need an adapter. And if I do so, which adapter would fit.

 

Sorry for all those questions. And thanks for those willing to help me.

Best regards

Olaf,

 

I believe this is your best chain:

G1|(AES) --> Mutec MC3+USB| (AES) --> Mytek Brookly Dac+ --> Headphones

 

It's the shortest, most efficient, using the best available protocol under this scenario.

 

Next for the clock:

A.  You can feed the Brooklyn with the word clock from the Mutech. I believe both are 75ohm. Whether the MC3+ has a better clock than the Brooklyn is subject to research.

B.  Mutech clock cannot feed your SOTM (I suppose it has the clock board installed).  That board expects a REF10 signal, such as the OPT13. However, adapters are far from optimal so your results may vary.

C.  Alternatively, you can feed the MC3+ with the signal from the OPT13, which will affect both the MC3+ and the Brooklyn if you end yo feed it with the word clock from the MC3+. Again, employing an adapter may not be optimal. 

 

 You can't do both C and D, because the OPT13 has only one output.

 

Here again, I'm glad for choosing the REF10: 8 outputs some which are 50ohm and others 75ohm.

 

Good luck! 

  

 

 

[Olaf P]

Hello LowMidHigh,

thank you very much for this feedback to my question! I will follow it.

 

 

[Olaf P]

I have changed my SOTM equipment to the 75 Ohm Version. But the SOTM equipment does not lock to the Mutec although all are 75 ohm.

Does the SOTM stuff not work with the Mutec MC3 USB?

 

My Dac locks easily to the Mutec.

 

[justubes]

Olaf,

 

Yes it does not work!

 

As MHL stated, your best option may be to buy a Mutec Ref 10.

 

The Sotm devices all required to be fed a 10Mhz signal from the Ref10.

 

MC3.1+USB does not output 10Mhz, Only audio clock frequencies, it has nothing to do with 50 or 75 ohms.

Hi justubes,

 

thanks for your help. So another 3K Euro to leave my bankaccount

There may be an option, please contact kenji on your Cybershaft op13 as they offer a clock 10M distributor with 3 outputs.

 

This will allow more 10Mhz outputs.

 

You can connect the op13 to the Mutec/Cybershaft  clock distibutor to allow multiple 10Mhz outputs to connect to your MC3+ USB.

 

A really simple way is to use a bnc T joint. Kenji does not recommend this as this put a strain on the op13 and can shorten the life and damage the output of the clock.

 

This will add more equipment and cables and personally feel may not be the best solution.

 

The Mutec Ref10 is the best option (equavalent to op16 and above). Cybershaft has Limited2 model with 3 outputs, but may not have stock currently. 

 

If you are not considering a lower phase noise clock, ask Kenji if he can use you can send your op13 to him and fit the existing ocxo in to his Limited2 model unit using your op13, this may be the cheapest and also a tidy option.

 

From a performance perspective, a Ref10 just using 1 output to either the MC3+ usb or the Sotm will possibly provide even better results that having an op13  feeding both the mc3+usb and Sotm together.

 

If you read Marks comments on his experience with OPn and Opn+1 or 2 may not bring improvements or may in fact sound worst.

 

I had posted before that one has to take into consideration that the different brands of OCXO of the same OP level will still differ with very different Allen variances and deviances.

 

Further, i might add, that the different make of OCXO will already sound different even if every parameter is the same.

 

The circuits and transistors used inside different OCXOs will most definately have a different sonic presentation by itself.

Thanks for your detailed answer.

 

I will try the clock distributor and already ordered it.

I will post my feedback as soon as I have enough time to listen to all the different options you mentioned.
