Rubidium Clock

In the way of an update, I have the Cybershaft Rb+OCXO 'dual master clock' offering up and running as of late and I am extremely impressed by the build quality of the unit and the customer service provided by Hasegawa-san at Cybershaft.  He goes to great lengths to ensure all questions are answered and provides unit-specific test data for ALL testing of the unit including Allen Deviation, reference measurement devices used, etc....It's the most specific and open backing of what a unit truly does after it is built I have ever seen.  The price point of the unit is a fraction of the other offerings in the space (that provide 10 Mhz atomic-precision master clocking) and frankly when I saw the unit, it's quality, appearance and sheer weight coupled with the exceptional customer service, I don't fee that I am missing out on a single thing compared to the offerings from Stanford Research, Isochrome/Antelope or others. I currently have this connected as follows;

Cybershaft Rb-output=>10Mhz=>Esoteric D02 (WRD CLK IN, 10Mhz)=>Esoteric P02 (MCLK frequency from the D02). 

Put another way, the Cybershaft clock is providing an atomic-precision baseline for the clocking circuit of the D02.

All the specs and other technical aspects aside, there was an immediate improvement in the natural/liquid nature of the sound when I enabled the 10Mhz input signal from the Cybershaft to drive the WRD CLK Input of the D02 over the D02 alone. All was extremely good before but I find a touch more precision in image size and placement (of instruments and voices) and an even more musical presentation overall of the system as a whole.

I am very happy to have stumbled on the company out of Japan that as it turns out produces alot of these and similar devices for broadcast and recording audio and video firms and audiophile users in Asia.  My hat is off to Hasegawa-san and his team for building on hell of a component at a fair price and topping that with some of the best customer service and attention to detail I have ever seen!

Fascinating find. I may have to consider this to work with Mutec 3+usb converter.  Can you please let me know the part # of what you purchased? 

Good Day tboooe!!! Great to hear from you,...hope all is well!

The model number is RBOCXO-01,...send me an in-mail with your current email address and I'll be happy to share the calibration data and manual from the specific unit I now have.

Thank you zephyr!  Things are good thank you!  I hope all is well with you too!  I am really happy to have found this thread as I have been thinking about adding a clock to my system.  Actually I was thinking about this waaay back when I still had my Esoteric P3-D5 combo.

I am a little embarrassed to ask this question but what is the difference between the 10M clock like this one from Cybershaft and a work clock like the Esoteric G-01?  Also, the Cybershaft websites states that it is ok to plug their 50ohm output into a 75ohm input of the downstream device.  Is this correct?  

Again thank you zephyr!

Zephyr,

The newer X version over the non-X or your D-02 uses the same clock input connecting, however, it is menu selectable to accept 10M input as well as a masterclock input of 22M (the new D-02x has this function.

The Rakon OCXO used in the cybershaft has impressive specs (possibly delivering better short term phase noise) as opposed to any Rubidium module. Not sure if sonics, beats say the G-01.

Maybe Hasegawa-san has tested or compared.

The benefit is the capability of running the master 22M from the G-01 directly to the newer Esoteric players/Dacs. Essentially bypassing all clock circuits of the player/Dac.

I believe that a separate clock, whether a 10M or G-01 unit has over the internal clock of the Esoterics is much more attention and contribution is made by the beefier power supply lacking in the players/dac.
