have mutec ref 10 for gustard a26
I use this cable 50ohm now

much better sound

I have the Tubulus Concentus on order. Hope it’s a jump from The Harmonic Technologies which are pretty darn good.

I was amazed at how much better it is than the HT.

Don't forget, it needs a long burn-in (silver always does). Give it a month with the clock running and you will hear a new level of transparency.

strange question
I only believe that 10mhz clock
and clock cables match
and what is measured
nothing else

Clock signals have been standardised for decades. If they weren’t, then ADCs and DACs could only work with an external clock specifically made for them, rather than with any external clock (for digital audio). That standard calls for a 75 Ohm clock cable. However, this is not applicable with I2S, because I2S was never designed for connecting different pieces of equipment and therefore contains no external clocking provision. In other words, unlike other digital audio protocols, there is no correct clock cable, it’s whatever a manufacturer decides.

It’s therefore even more likely you will introduce even more jitter and therefore more jitter artefacts (noise and distortion) with externally clocked I2S (than with other protocols). Although that appears to be what some here desire, even though they are claiming they’re after lower noise/distortion (higher fidelity). This is “what is measured nothing else”.

Thanks everyone with your technical and subjective support. I got the 50 ohm bnc from aliexpress. I found sine wave to be tad better than internal clock of R26. It’s an improvement and noticeable.
On squarewave it has gone another level in terms of dynamics clarity and airiness but i find a slight harshness. Maybe that will go with burnin or not?
Any recommendations for bnc cable?
I am using burson timekeeper 3i amplifier with spendor classic 4/5 on desktop setup. Running roon, jriver and Apple Music.

For the LHY OCK-2 do you recommend turning the clock off if not used for a period of time >24hours or should I just leave it on 24/7 set it and forget it?

Thanks in advance.

No, Keep it running for longer times to get the best out of it. If You are abroad for a long time turn it off. Enjoy life!

Try adjusting the filters within R26, that could help smooth things up. Try to use square wave wherever possible, clock cable also affects the sound a lot, if the aliexpress clock cable is harsh, try Harmonic Tech, HT cable definitely is not harsh.

It takes a long time for the clock to sync everything.

Once disconnected, it will take a while to resync.

I dont know how long but I think someone mentioned a week or a two.

Any idea where to purchase the HT cable in the US?

 

[xkamran]

Very interested in the difference of those two.

I have something similar to the pasternack cable.

Hi where do you get your lmr 400 bnc 50 ohm cable from?

Audio Accessory Hong Kong sell it, the only place I could find that ships it as a complete cable.

Where are you located?

I got mine in the US, via eBay:

Note that this is the more flexible version, which is a must, IMHO.

 

[PeterCraig]

If You are abroad for a long time turn it off.

That's when you burn in the new clock cable.

Alright. Forgive my ignorance about switches. I have a gustard r26, using lhy ock 2 exrternal clock, with ifi lan silicner and running it with roon. In my setup would a network switch makes any difference? is a network switch replacement of external clock since it has an internal clock eg lhy 10 switch?

Where do you get from?
