Reality is Cruel : Cybershaft new Ultimate OCXO 10M Clocks Shootout OP20 vs OP17
- Thread starter CKKeung
- Start date
I can only confirm CKKeung and scaudiophile. I use dcs vivaldi clock and cybershaft Op21A..
I’m a bit confused even more then typical
I remember Reading some white papers based not just on hearing perspectives alone
these were measurements
a spidif cable it was noted to be critical to Match imp on cables to all devices.
so in reading above has anyone done measuring to see ?
lastly I always felt internal clocks made a better sound aside of studio usage.

My sister's system is N-01XD & F-03A with cybershaft OP20A (not OP21A) that has just been arrived from Cybershaft last week.
Cybershaft Japan has shotdown their online shop since the middle of January due to their factory movement.
They will soon relaunch their online shop and also newly open it for foreign customers.
Firstly you don't need to introduce Esoteric's clock system. Because N-01XD accepts 10MHz clock directly from Cybershaft's OPXX.
And N-01XD automatically accept both of 50-ohm and 75-ohm signals from it.
According to Hasegawa-san, CEO of Cybershaft, many Japanese owenes of N-01XD are using Cybershaft's master clock generators.
His products have good reputations from N-01XD users.
You will be able to feel rich sound stage with improved sound quality as soon as you connect N-01XD and OPxx.
My recommended BNC cable is "XP-DIC/BNC EN SE: 75 ohm BNC cable" of Cross Point(Japanese maker).
My sister is using two cables : one is Cross Point's 75 ohm BNC cable for N-01XD and another one is SOtM's 50 ohm BNC cable for SOtM's switch.

Thanks for the useful info!
Cross Point makes very hi-end audio accessories.
Their power receptacles are awesome! Uncommon in Hong Kong but two frds of mine are using them very happily.
CK, more from me as always!!
They are making high performance audio fuse,too. They are very expensive (JPY 107,000/pc).
I'm using SR's Purple fuses for Bartok, HPA4 and Octave's V110SE.
AMPs improved sound balance and DAC improved sound quality very much!!
As you have already recommended in another thread, fuse changes everything!!
Near future I'd like to try QSA's Black/Red fuse ( infortunately Silver is out of budget) for my DAC.
PS. Today I ran the following clocking impact comparison by using above mentioned my sister's system.
1. 10MHz clocking with SOtM Switch only (with SOtM's 50 ohm cable)
2. 10MHz clocking with N-01XD only (with Cross Point 75 ohm cable)
3. 10MHz clocking both of SOtM and N-01XD
Result was 3 >>1 > 2 Clocking with Switch only was better than clocking with N-01XD only.
HTMUSIC, thank you for the information.
How do you feel GND with Isolate or chassis?
I am thinking of SAEC PC-Triple C / EX and Habst.. Any comment?
Hello cykin,
You can use both of 75ohm and 50ohm cables for N-01XD as my sister is using SOtM's 50ohm and Cross Point's 75ohm cables.
In their owner manual & page 9 shows...
"Use commercially-available BNC coaxial cables for connections. o BNC coaxial cables with 50? or 75? impedance can be used"
I've set GND with isolate based on Hasegawa-san's recommendation. I have no experiences with GND with chassis.
As to BNC cable, I have experiences of using the following cables so far.
1. Cybershaft's standard cable
2. SAEC's DIG-T50 (lower price's) USD 100 or so
3. SOtM's BNC 50 ohm cable (middle class but very good performance) USD 700
3. Cross Point (High-end) about USD 2K -> I was using this before. Now my sister has taken over it and has been very satisfied with the great performance.
4. Brise Audio's MURAKUMO (High-end) about USD 7K -> I believe it must be No.1 BNC cable in the world.
I'm using it for SOtM's USB reclocker and switch.

May I know which power cords do you use for N01Xd and f03a? Which XLR to connect them? Thanks again.
Of course, therefore I’ve spent much money for Brise's MURAKUMO BNC cable.
Briseaudio Highend audio cable company
We are using local supplier's power code and XLR cables.
As you may know, the voltage in Japan is 100V.
My sister is using CHIKUMA's power codes (price range: USD 1000/pc) for them.

Interconnect XLR and speaker cables used for Esoteric system were made by an old engineer (around 70 years old) who worked for Nippon Telegraph and Telephone Corporation. Unfortunately you can't get them from outside of Japan.
For my system DAC:dCS Bartok+ and AMP: Octave V110SE, I'm using Brise Audio's MURAKUMO XLR and above mentioned custom made speaker cables.
I hope you can find a good BNC cable soon.

Interestingly, I've found the switch set to GND sound a bit more open compared to the "Isolate" setting.
Regarding BNC cables, I've switched from standard cables to the solid-core silver Oyaide DB-510, and I'm very happy with the improvement in tonal clarity. I'm using these cables not only from the Cybershaft to the wordclock device, but also from it to the DA converter and interface. Due to the improved high-end frequency response due to these cables, now I've found the 75 ohms and low level settings to be the best sounding ones (previously, I tended to prefer 50 ohms and/or high level setting).

With respect I will point out this is one area where the translation of the manual and its original content are misleading.
There is "can" and there is "should"....
The manual states ""Use commercially-available BNC coaxial cables for connections. BNC coaxial cables with 50? or 75? impedance can be used".
That is absolutely true however it is terribly misleading in that the reason it's true is the unit has both a 50-ohm specified INPUT and a 75-ohm specified clock OUTPUT that can be used with downstream devices with either OUT44 or OUT48 (see manual for text on all of this).
In other words, yes you "can" use both 50-ohm and 75-ohm cables with the unit however, you "should" use a 50-ohm cable with the 50-ohm input from a 50-ohm output of suitable clock and you "should" use a 75-ohm cable on the CLOCK OUTPUT if you use that.
While 50-ohm is the stronger of the 2 standards in terms of data bandwidth, etc...supported and several of us here and on other forums have done months of blind listening tests some years ago and found that 50 can be used in place of 75 without much downside, the substituting of 75 ohm to carry a 50-ohm clock signal leads to some interesting side effects in imaging precision, instrument size, soundstage depth, etc...with certain units that were in the testers' systems (Esoteric, DCS, other and clocks from Esoteric, DCS, Cybershaft, and other). When a proper 50-ohm cable with proper 50-ohm termination was used, the side effects disappeared.
Offering this as opinion only, your mileage may vary and all that.
In this case the Esoteric manual(s) could be much better written and more explicit. They do however explicitly state in the input/output specs list section that the input is 50-ohm and the type of signal whereas they list the output is 75-ohm and the signal characteristics. It seems they mean users to adhere to that when choosing cables and connecting devices.
Lol and. I say it’s not ideal and get crickets. lets see how you do
To get the best measuring clock and then introduce impedance mismatches has seemed counter-intuitive to me. Some are saying though that impedance mismatches matterfar less though with sine wave than with square wave. Which type of clock signal yielded the side effects you folks heard?
