![]() ![]() 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. 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. 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. You may read more here (use Google Chrome and let it translate the page) I will report back and let you know my findings between mid-late April after I receive it and break it in. Unlike the PERF10 or particular FS725, this Cybershaft unit seems to have a better internal PSU but I'm not discounting the potential move to another HDPlex power supply with a retrofit in the future to get an even better bespoke PSU to drive the Rb-clock. This should surpass the already great performance of the D-02 clock circuit by a clear margin. I plan to use this 10Mhz reference clock sync to drive my Esoteric D-02's clocking baseline while leaving the D-02 to sync itself and the P-02 transport together at 22.5792 Mhz. I have taken the plunge and ordered one as of yesterday this should be a very nice and affordable test. #Bnc word clock plusThe Rb-only unit has a single FIFTY (50)-ohm BNC clock output they supply all their test and calibration results with each unit plus a 1 year unconditional warranty. They are rated for 100-120V and 50-60Hz use which makes them perfect for US or Japanese usage. ![]() ![]() It seems they make OCXO, Rudidium-only and OCXO+Rb clock units (single port each standard) for high-end audio, video and studio purposes at an extremely aggressive price point (the Rb-only unit is about $1300-$1500 USD depending upon JPY->USD conversion rate). I stumbled on Cybershaft Japan as an option via listings on various sites. The lead-time on the PERF10 or FS725 is longer than I would like to wait personally and my RFQs out to LibertyTest, AllTest and other certified/used equipment vendors for a PERF10 or FS725 have come up dry at the present time. I've done a lot more research in this regard and have had a number of conversations with SRS as well as other options. ![]()
