Why?

Supra has a good measurement for there 75Ohm. I can recommend them. Trico series

They are not coaxial cable, see my captured pictures

Because of the cables listed at 38 and 53 ohms, just totally whacked-out with no known application

Are you saying the Neotechs I listed aren’t coaxial cable?
You are 100% wrong if so.

I don’t think you understand cables and ohms.
The impedance given in a coaxial cable data sheet is its "characteristic" impedance, not its actual impedance. What that means is that "50ohm" coax will have the least loss when the output impedance of the transmitter is 50ohm with no reactance, and the impedance of the load is also 50ohm with no reactance.
The above neotech cable would be fantastic for 50ohm clocks with proper BNC connectors.

Just curious how to fix these kind of cable into BNC connector

Depends on which one you choose
The rectangular wire would be great to split and have a tidy dual BNC for multiple devices.
Neotech NESW-5001 would be great on its own as a single.

Found this one from ebay, the title is subwoofer cable, the price not high at all, but it is good to use in high frequency 10Mhz clock cable?

LHY is a mixed bag with the OXCO. I think some are in the spec range and some are out of spec. Its a lottery.
I jumped also on the LHY hype train last year and bought the OCK-2 and thought it is a improvement to the R26 K2 but after a couple months listening with the OCK-2, i took it out of my system and there was no difference in SQ.

I hear You all but I have a hard time to accept/swallow the message. I must be the luckiest guy to have got two different LHY clocks, the OCK-1 and the OCK-2 where both performs very well. My OCK-2 impacts with a clear A-B result on Agd DI20HE+R7HE Mk2, U18+ X26 Pro, R26 and the A26. I still stand for my text in my review and the summary still holds here in my rig. In some time I will try to rent or lease a high end analyzer. Here where I live a relevant calibrated unit is rented per month for around USD3500 with insurance and to buy it would cost about USD55000 and up depending on precision. Best option should probably be to buy a few hours in a calibration-lab with a skilled technician in the right envirolment doing the real testing. I have to investigate the posibilities here where I live.

We''ll see when..

It surprises me too. I listened to each 0.5m cable separately and they sounded identical to the whole cable. I did make sure to use each piece in the marked direction and crimped, not soldered, the plugs.

I let the 50cm cable in the system last night, let the clock and DDC turn on, tonight I listened music again, I found the music detail is same as 1m cable, it is because the short cable burn in or my brain burn in?

Oh for sure
We aren’t even at high frequency yet as far as cable is concerned
2ghz is the limit
Radio is 20mhz

This one should be easier to fix in bnc connector, can put it in the list for fun test. How about the impedance matching the source and load 50ohm? Another question do you have idea cable has sin wave and square wave type for clock purpose?

It needs quite a lot of burn-in. Give it time.

You’re seriously trying to reinvent the wheel with these cables? There’s a good reason rf cables are coaxial and well shielded.

Yup
Now you can see why 50 ohm/75ohm doesn’t really matter at all for 10mhz clocks. I wouldn’t even start to worry about transmission line effects until 50MHz and a cable longer than 60cm.

Harmonic Technology Digital Copper III 75 ohm BNC-BNC vs Digital Silver III

After 215 hours with the Digital Copper III from the Mutec Ref10 SE120 to the AGD R8HE 10MHz input, I swapped the Copper to the HT Digital Silver III and after about 6 hours it was apparent that the Silver III sphere of holography expanded noticeably beyond the Copper. It was really nice to experience commensurate performance with price increase, especially for such a modestly priced product suite. It's hard to put a percentage of magnitude on this as these are spacial enhancements in the spherical domain vs lateral sound stage expansions beyond the boundaries of the speakers out to 180 degrees as I was previously used to. But the spacial demarcations of voices/instruments within the sphere are noticeably and vividly more unto themselves and for me adds a new sense of thrill to the listening experience.
A more artificial studio piece I always come back to is Led's "Since I've Been Loving You" where the kick drum, bass pedals and vocal occupy the phantom center channel, the rest of the drums are out of phase to the right from 0 degrees to about 40 degrees and the guitar [before the solo] appears around 100 degrees and the keyboard is 135/45 degrees. The system spacial improvement shows up as more silence between the instruments making the out of phase mixed instruments show up as more vivid and real as opposed to previous upgrade improvements to my system where there were "degrees of less vagueness".

Also, the loud brass transients on "The Name Is Bond" from the Casino Royale sound track are presented much more convincingly with the Silver over the Copper to the same effect that the Copper was in a completely different league over the DH Labs Silver Sonic.

I probably shot myself in the foot on this one, but for $62 shipping, I bought a few extra cables and I still have the new Copper III for $158 with PP/Ship included to CONTUS if anyone has been holding back because of the $45 shipping from Labkable.... [SOLD - 4/26]
