Cybershaft 10Mhz master clocks, new products at various price points....

IF you will always have an intermediate clock like the G-03X that takes a 10Mhz master clock input to provide it with a better baseline and can connect everything to it, then i would suggest driving the G-03X a good solution would be the single output OP21A from Cybershaft with the separate DC power supply for best results;

Model number: UPOCXO-OP21A-1 External DC dedicated
Model number: LTPW01P External DC power supply

I have no direct (personal hands-on) experience with the EtherRegen so you'll need to consult that product's specifications to make sure you can clock it with the G-03X.

You may also consider selling the G-03X and getting the multi-output Cybershaft however you'll want to ensure that all your equipment takes a 50-ohm or 75-ohm 10Mhz input signal.

Unfortunately, based upon what I just reviewed in that Esoteric unit's specs, it only accepts Word clock frequencies, no master clock, i.e. 10Mhz input allowed. This means it cannot sync with any Cybershaft clock model as they are pure 10Mhz.

@cycles2 I would suggest downloading the manual and reading through fully before ordering of course.  If memory serves, my G-0s and later models I owned like the G-03X all required you to set the clock frequency manually, no auto-switching; this gives the best results as the gear is not deciding for you.  I always found that 176.4 kHz and later "MCLK" word clock frequency of 22.xx Mhz were best for playback clocking; i would not want devices thinking for me on the fly and auto-switching.

@cykeric There is no difference in audio result as far as I've heard.  It's only a matter of what matches better with your gear for acquiring and maintaining clock-sync.  For Esoteric, LOW is best.

Good Morning @cycles2 !  From what I see on the DCS site, the Rossini DAC can only accept word clock input frequencies at 75-ohm;

"2x Word Clock Inputs on 2x BNC connectors, accept standard word clock at 44.1, 48, 88.2, 96, 176.4 or 192kHz.
The data rate can be the same as the clock rate or an exact multiple of the clock rate. Sensitive to TTL levels. Word Clock Output on 1x BNC connector. In Master mode, a TTL-compatible word clock appears on this output."

The Rossini DAC is a great a sounding unit, a couple of friends, on in Atlanta have it, the transport an the Rossini clock and the result sounds great used together. Unfortunately the Rossini clock does not accept a master clock input and I believe it's a VCXO, not an OCXO implementation (there is little published on it so I may be wrong so don't shoot the messenger if I am...).

Friends with DCS who have the Vivaldi clock have found that using a Cybershaft with it ups its playback quality and either use it plus Cybershaft to reclock Vivaldi or Rossini gear as follows;

Cybershaft drives -> Vivaldi clock drives -> Rossini or Vivaldi gear

All that said that may not be the feedback you were hoping for however those the limited permutations given what the DCS BNC inputs take in and what they do not.

Note: I'm not saying anything anything against DCS, just reporting what is possible.

If you go the Vivaldi clock route (or any other than can work, the best combo of Cybershaft gear is;

Model number: UPOCXO-OP21A-1 External DC dedicated
Model number: LTPW01P External DC power supply

next after that would be the OP20 level and then OP19 at lower price points.

***If you don't already own the DCS Rossini streamer/DAC, you MAY want to have a listen to the N-01XD (new with Esoteric's latest FPGA-based new DACs; they are fantastic and the N-01XD is already amazing the 3 people I know who have bought it. 

You CAN then directly use any Cybershaft with the N-01XD or Esoteric P-02X/D-02X, Grandioso K1X, P1X/D1X, etc...

I've heard the new DAC implementations in the D1X; they are absolutely world-class, even more musical than prior top Eso offerings and given FPGA use and overall design they are future-proof. Believe they also do MQA, and other popular things but I am not a server/streamer customer so what I've seen on MQA, Roon, etc... is from reading their site.

Other options; from what I've heard and read, Aurender's W20/W20SE can take in a 10 Mhz signal.

SOULNOTE's S-3 CD/SACD player and D-2 DAC can also take pure 10Mhz. Reading between the lines of a couple of communications, I think they are also working on other new things for their top offerings but have nothing concrete to state at this time.

Hope this helps...

@cycles2 There definitely will be many new things to obsess over in 3-4 years, probably 1-2 and again 2 years after that, again after that and so on and so forth!

The Rossini clock made an improvement in my Atlanta-based friend's system however his system overall is very high end and resolving in terms of speakers, amps and pre-amp spend. That stated it was not an earth-shattering improvement. If you want a Word clock that is compatible with your Rossini DAC, I'd suggest the Esoteric G-02X; it has reasonable price, better build quality and a full OCXO implementation. This is all opinion mind you.  It also allows for a 10 Mhz input 50-ohm for future upgrading. I think it will deliver a more pronounced improvement.  It's Word clock outputs at 75-ohm and have a wide varieties of WCLK frequencies to utilize to find the best match;

Esoterics G-01X is also an option;

@thyname  Yes,...they are forgettable LOL!  

@thyname Thank you very much,...I appreciate the comments very much. Truth is, I don’t spend much time here like I used to. Watching the forums go to hell over the last few years with a lot of argumentative and trolls’ posts and too much focus on the dealer-centric ’new Audiogon’, I was missing the old days when more people helped each other out and this was a great forum. I’m going to give it another try and see if we can’t get Audiogon back to what used to make it great!

@cykeric I do not know regarding the SOULNOTE....being an audio consumer, I can only tell you what I’ve either directly tested or what people I know of with specific gear and Cybershaft clocks have told me or written directly. On the SotM product I only know of 3 people personally (there are more but I don’t know them) who master clock SotM devices with a Cybershaft. The product you ask about seems to require an add-on adapter to take a 10 Mhz input so unsure about that one.  

You might try posting your question on the Cybershaft threads on What’s Best Forum; there are several guys from Hong Kong and other locations who try many different clocks with many different devices; it’s possible one off them have more experience with SOULNOTE and SotM.

I wish i could get my hands on a SOULNOTE P-3 and D-2; they look fantastic and at a price that is reasonable. I only wish they utilized the new Rohm Semiconductor DACs that Luxman just included in their top player or AKM’s 4497 or 4499 as used in the prior Esoteric product top-line.

For anyone interested now or in the future, I've recently been told that Cybershaft now has an "Overseas Web Shop" all in English:

[ NEW Cybershaft Overseas Web Shop ][/B]

http://cybershaft.shop

the legacy Japanese site

 still works and you'll find a link to the above on the "For overseas (English)" menu item...
