Clocks [not Coldplay]

I give you that, it sounds like nonsense propaganda, but the articulation on the Oracle Ma-X series actually do work, please try it before any judgements if you haven’t. :+1:

Perhaps I should have elaborated in my original post :wink:

MIT’s “articulation” is marketing-speak for a modified Zobel network for impedance matching, and frequency response flattening. MIT also hints at dielectric dispersion compensation, but thats rubbish since its immeasurably tiny for frequencies & power involved in audio systems. Those articulation graphs are bogus. IMHO, MIT cables are only really useful for interconnecting mismatched systems or systems that are somehow otherwise compromised.

I used to own the Oracle v1 speaker cables years ago when I had VTL Amps that were a very far from my low-impedance speakers. They worked well enough for that system.

MIT cables are not useful, and likely sonically detrimental, to interconnect dCS components. :metal:t3:

Thanks @Anupc. I was hoping you might provide a more technical explanation. And after doing a little searching and reading, I know a lot more about Zobel networks than I ever expected. :wink: From reading the reviews, I had been wondering if this was anything more than impedance matching, perhaps slightly more. Sounds like MIT cables could be useful for some amplifier loads and speaker runs.

I know of Spectral audio, who design their products to work specifically with MIT cables. On their frontpage: http://spectralaudio.com/

Great story.
I know 0 about clocks, at least the audio kind.

I have a Bartok; I understand a dCS Clock would turn up the magic.
Can someone explain in non clock terms, where a Cybershaft clock would fit in , would I need a dCS one too and lastly, Cybershaft’s website is 98% written in Japanese… you guys are also fluent in Japanese?
How much is this thing? I(I know… if you have to ask, you can’t afford it).
Building a working man’s system here…

Thanks

Yes, Bernard! :rofl: But wait, no. If you run the site through Google Chrome—FYI, I am a true Google-“hater” and will normally do anything to avoid using Google product or services—it becomes very comprehensible with Google’s good translator.

The Cybershaft [or any other reference clock] provides a 10mHz reference clock signal to a dCS Clock through that unit’s 10mHz clock input. In theory, it helps the dCS word clock be even more accurate and stable. It is not a necessary addition for the dCS Clock to provide its magic. When I demo’ed Bartok, I found the Rossini Clock notably improved its SQ. External reference clocks range from a few hundred dollars [and likely a complete waste] to nearly $50k for the Abendrot, and probably more for others I don’t know. The TOTL Cybershaft is about $7k+USD. There are other high quality offerings from Stanford Research and Mutec in the $2-4k range.

Addition of the Rossini Clock to the Bartok. IMHO, is a easily apparent improvement. Addition of an external reference clock will not have as significant an effect; more subtle.

Thanks;
I was on the Timex website before this information. :slightly_smiling_face:

You could upgrade your Bartok using a dCS wordclock. However unless you have the headphone version and that is essential to you, IMO you would be better off putting the money towards a Rossini. However if the more expensive DAC is out of the question then adding the Rossini clock would certainly improve the Bartok.

The dCS clocks and the Cybershaft clock are not interchangeable and do different things. Your Bartok already has a very good inbuilt clock. An external dCS wordclock improves upon this and provides a more accurate timing signal at the required frequencies of 44.1 KHz or 48 KHz or multiples thereof. Basically the external wordclock is providing a more accurate reference to the clock in the Bartok.

The Cybershaft or a similar device is a 10MHz clock that cannot be connected to the Bartok. It provides an even more accurate reference for an external dCS wordclock. However the wordclock in question needs to have a reference input to cater for it and this is only available on the dCS flagship Vivaldi clock.

I hope that helps.

Very good.
Much appreciated.

Pete, thanks for that clarification. I had not noticed at the time I demo’ed it that Rossini Clock did not have a reference clock input, and incorrectly assumed it did. My error. Regrets for any confusion I caused.

@PAR
Pete, in your estimation how much would I need to spend on a clock where I’d notice a definite improvement over the built-in clock of the Rossnini? I’m thinking SRS Perf10 for $4k or the SRS FS725 for $3k. SRS states that the 50 ohm output of the FS725 will work as well as the 75 ohm output of the PERF10.

Thanks,
Brian …

I’m afraid that have no idea about clocks other then those made specifically by dCS for their components.

Like Greg’s comments about cheap 10MHz clocks I suspect it may be easy to waste a lot of money as clock performance is far more complex than just generating a steady pulse. I am also sure that dCS will tell you that it needs to be 75 not 50 ohm.

In any case these SRS clocks are NOT what you can use as they are 10MHz rubidium clocks. As per my earlier posting you need to buy a Vivaldi clock first to use a 10MHz clock with it . For your purposes you need a clock with 75 ohm 44.1 kHz and 48kHz outputs and the ability to autoswitch between them and multiples thereof as the files that you are playing change resolution. You really do not want to find that you need to manually reconfigure the clock output every time that you change from redbook to 24/96 or internet radio etc.

So the answer to your question is really only the Rossini clock which may not be what you want to hear as it costs ( I think) around $ 7.5K.

Brian, because you have Bartok, Rossini Clock is your best (maybe only) real option. Rossini Clock brings Bartok very close to Rossini, even taking into account the firmware differential. So, if Bartok is already your endgame, then Rossini Clock is very much worth trying, especially if you can demo it in home or at least have a return privilege with your dealer. I heard what Rossini Clock did for Bartok over headphones at my dealer, and I was impressed.

And if there is a chance that Bartok is a stepping stone toward Rossini, then Rossini Clock might make even more sense as your first piece of Rossini kit. It will only become more impactful.

Speaking from my own experience, if you’re at all interested in improving your clocking, the. best first investment is the dCS Clock that will work with your equipment. The third party 10mHz clocks like Cybershaft, Mutec, or SRS will have significantly less impact due to the quality of dCS Clock you could already own.

Yes ultimately less impact as he cannot use them no matter how hard he tries ! How often do I need to explain that a 10MHz clock will only work in a Vivaldi system? The OP has a Bartok.

I know that Pete, as I (thought I) acknowledged earlier. I was simply speaking broadly to the impact of clocking within the dCS family, versus using a third party reference clock, and their relative impact, purely from my personal point of view. And if he finds himself on an upgrade path, well then . . …

Sorry Greg. I must have been a a “snappy” mood last night.

Hey, no worries; I know the feeling! And sorry that my reply wasn’t a bit more diplomatic. I don’t know how everyone else is doing, but we’re all feeling a little emotionally threadbare here in our little corner of the world. Don’t get me wrong; we’re very fortunate to have access to all the supplies we need, and we live in a single family home with a large lot, so there is plenty of safe space. But we’ve got five adults 24/7 at the moment (due to timing circumstances and university closures), where normally we have two. And even with lots of outdoor activity, that sense of close quarters can sometimes get overwhelming. I hope everyone here is safe, healthy, doing well and enjoying as much music as possible. :laughing:

Space is one thing that I am short of as I live in a London apartment. What we call a split level maisonette here ; is that a Duplex in US English? London apartments are the size of closets in my American friend’s homes :slightly_smiling_face:. With my adjacent neighbours including several children who sound like they spend their time either trying to murder each other or in practising mountaineering up and down the wooden stairway that buts against the other side of one of my interior walls life can be a bit fraught.

Anyway stay safe and don’t try injecting disinfectant :wink:

I’ve briefly lived in a townhouse in Chelsea, and stayed in many a small hotel or flat on various business and personal trips. You have my sincere sympathies. I have three words for you: closed back headphones. I mean that lightly, of course. I know they don’t solve anything. But a little escape now and then makes all the difference, eh? Stay safe and healthy.

:joy::joy: dCS should print a red cross on their products.
