Rubidium Clock

Sibelius: Thanks for letting me know,..

Interesting discussion. I'm using Oscilloquartz 8607 powered by custom PSU and very happy with results in my Aurender/dcs system. Problem now is availability of 8607 on used market so your option could be very interesting alternative

That looks to be one outstanding OCXO clock module...phase noise and precision specs are really impressive! It reports discontinued unfortunately....this seems to happen alot from what I've seen recently.  I'm told that vendors often will buy up 1500-2000+ units of such a component when they find it and test it/validate its quality just in case. Very similar to what happened alot in the DAC chip market and how some vendors (AMR, others) have chosen to proceed (which is a good approach IMHO).....

Hey Zephyr,

I just had to...... Thanks Zephyr for contributing Cybershaft's excellent OCXO at affordable prices!

Just received from Kenji an option 16, -116db/1 Hz OCXO hand selected/tested from many OCXO's.

The packaging was 1st class all the way, just beautifully well packaged and delivery was just too fast, i hadnt even expected it for another 2-3days. 

I have to run it in, nut off the bat, coming from a Quartzlock rubidium 110db/1 Hz into a G-02, what i am experiencing  exactly echos your comments from switch from rubidium to OCXO.

" I had precision in many ways but not the beauty and naturalness I am experiencing with the lower phase-noise OCXO-based presentation."

The Rubidium has maybe better sparkle or "brightness", not in a really bad way and a bit more pyrotechnics in the bass... I would term it a hardness and some glare which i did not really find distracting with careful tweaks and room adjustments. Rubidium thus lends to a brighter, showy or flashy presentation.

Cybershaft's OCXO is just so much more grounded in the mid regions  and has zero brightness that i can tell so far from any genre's of music now, even "poorer" commercial recordings.

Hi Custodian, i appreciate your comment now of low phase noise from your BVA 8607..."Zero digital glare" from discussion from another forum.

I am not certain is this an combined artifact of low phase noise and also character OCXO as opposed to a rubidium unit.

I guess i have fueled my quest of experiment with clocks. Thanks to all, a most excellent resource in this discussion.

You are very welcome....it was a very lucky stroke to have come upon this company and their products via HiFiShark and then following over to Yahoo Japan.  Kenji and his team are consummate professionals and have done their best by a few of us who have taken up one or the other of their top clock models into our systems. As Kenji explained to me, the most precise clock is not the end-all/be-all for an audio or video high-quality system; he explains that alot of hardcore testing and real world use cases have proven to him and his team that the best strategy is to come as close as possible to the clocking standard and precision of the original recording. He has also further explained the fallacy (which I was guilty of same as others) of only focusing on "ppm" or "ppb" accuracy to evaluate our purchases of master clocks and to instead look at all the aspects of a clock's performance including Allen Deviation, Phase Noise, etc....to truly evaluate how that clock will perform.  Suffice it to say I've learned alot more in the process than I had ever picked up on before and I am glad that what I am hearing insofar as audible differences in my system with the clock is also being enjoyed by yourself and several others who all write about very similar positive experiences with this fine company's products.   Have a great day and Enjoy The Music!
