RCA cable recommendation for coaxial digital - up to 192kHz

[rhythm]

Hello,

I am using a WiiM Pro and using the coaxial digital output. To avoid a bunch of trial-and-error, I am looking for recommendations on RCA cables that you know from experience will work all the way up to 192kHz. I am currently using a Mogami 2964 RCA cable (brand: World's Best Cables) that I originally purchased for an analog audio interconnect, and it was fine up to 96 kHz, but silent at 192kHz.

Note: I did find an old set of component video cables lying around and I did have success using one of them for 192kHz files, so I know the rest of my setup is OK for playing 192. But this cable is way longer than I want to use, so I am in need of a new RCA cable that will work for 192kHz daudio.

Thank you,
Greg

For what it's worth, the Mogami RCA cables that I am using do have a 75 ohm impedance listed in their specs. As I mentioned, I did have an extra one and it worked fine for 192kHz audio. So the one that I was using may have an issue. I can still hang onto it if I ever need another one for analog audio.

I had a bad HDMI cable a while back and it took a while to figure out it was the culprit. The rear of my components are not easily accessible and it was quite the ordeal. If I had a swear jar it would have been over flowing.

Yes, I'm going to be in the same boat when replacing my cable in this case too. It's going to be a PITA.

Don't do that (other use), there must be something wrong with the soldering (take a look in the plugs) or is has a torn or cut wire somewhere along the cable.

Thx for the info. Mogami is indeed great stuff and WBC makes nice cables.

For 75ohm the cable must be coaxial (super cheap rca cables sometimes are paralel, but any decent rca cable is usually coaxial) but for 75 ohm the problem is the connector, it's not the quality or the material but the geometry of the RCA connector that simply cannot be 75ohm, nothing to do there; for 75 ohm the use of BNC connectors is mandatory, RCA 75ohm cables is simply misleading marketing.

Said that, for digital audio it's not absolutely nessesary, you can can use RCA cables completely fine for digital audio including hires, 75ohm BNC connectors are needed for other applications such as video etc.

One thing that I've seen many times (though I don't know the facts or if its realy true) is recomendations of using cables of at least 1 meter to avoid signal reflections that can increase jitter.

Any RG59 or similar cable with BNC plugs and BNC/RCA adapters will be fine.

That is a very good option but I bet not many use it
