On the D-02 or D-02X make sure you connect the Cybershaft to the "10 Mhz IN" connection which is (like the Cybershaft) true to 50-ohm connection spec.
Reasonably priced dual-master clock (10Mhz) Rb and OCXO....

Hi gents, how does one connect the clock to a Mutec3+ USB? I am out the AES of the Mutec and in AES of Yggdrasil...
Sorry for the newbie question.
Also, thanks for having me here
Since the Mutec can lock to any master clock signal 1-10Mhz (very impressive!), connect the Cybershaft to the Mutec using this input;
"
- 1 x BNC input for Word Clock + 1-10MHz, 75 ohms termination switchable, unbalanced
- Please remember to utilize a good quality 50-ohm to 75-ohm BNC:BNC converter on the Cybershaft end of a 75-ohm cable so Mutec sees the right impedance (75-ohm) and the Cybershaft is able to 50-ohms at the connector...
Thanks a lot!
Does the cybershaft exist in 220V too or only 110V? think I read this somewhere...

I believe you can specify 220V at time of order per the Cybershaft website;

Yes....at the cost of a decrease in magnitude, signal to noise ratio, and phase noise...
My friend just bought the $1000 CyberShaft Premium OCXO:
CyberShaft OCXO Premium
It already has much lower jitter than the $23.000 Esoteric G-01 Rubidium Clock, not to mention the $6000 Antelope crap:
He will test it with his dCS Vivaldi stack (directly connected to the 10M clock input on the Vivaldi clock).
If it performes as expected, we will try the $2800 Cybershaft OCXO Limited IP17 clock:
Does anyone compared the so called "crap" with the other models? Does anyone know how much is the phase noise threshold to achieve a good impact on audio?
Thanks Stereophonic, however the images are different, I guess it is new model you've posted, isn't it? I found the website: www.v-acoustics.com and did not find new pictures!
does it make sense to use such an external ref clock before an Yggdrasil? (in my case associated to my Mutec MC3+USB).
My question is whether the limiting factor won't be the internal clock of the Yggdrasil and as such, anything done before the Yggy would be negated by a potentially inferior clock within the DAC itself?

Hi SC.
I'm waiting for the new clock that you said....
I'm testing a prototype only as I said; there is no guarantee that it will be better than a great OP13 or OP14 implementation.
Surprisingly enough, in a recent test an OP28 (yes such things do exist but they are like unobtanium, 1 in thousands upon thousands tests out this good) based 10 mHz clock actually did NOT help the audio signal quality, imaging, musicality, etc...at all; quite the opposite. Even though the phase noise was almost immeasurable, signal strength was very low, locking then of course became much more difficult and most importantly, the resultant musical playback was not as good at all. I cannot give more details unfortunately but suffice it to say that I've heard nothing to date that beats a great quality OP13 or OP14 implementation. That may change but we'll see.
A fascinating read on what type of setup and care it takes to produce quality master clocking products and also what it takes to maintain the calibration and testing to do so;

Also,...I've concluded many months of testing with 2 additional OCXO clocks from Cybershaft whose OCXO circuit was even more refined than the OP13+ type 2 unit in my RBOCXO-01 and also with a loaned high-quality Rubidium unit (used to have the Esoteric G-0s but it is no longer in my system so I had to borrow its successor from a friend). Please note my earlier testing with an OP28 level device did not yield good a result set and musical playback result as I had hoped; the 2 latest units tested for several months were above OP13 but not as high as OP28....
At each step of the way, the idea that lower phase noise (and thus lower harmonic distortion and better Allan Variance (measure of short-term stability) were fundamental to the best musical playback, imaging, sound-staging and realistic playback has been proven as a fact.
In side by side comparisons of OCXO and Rb-based clocking, I found that I preferred, by a large margin, a high-quality OCXO clock circuit's impact on the musical playback experience every time.
