Quick question, I'm making an cable replacement for the Focal Celestee (3.5mm mono — same as Stellia, Clear, etc...). However, I only have 3.5mm stereo TRS jacks rather than the TS jacks that Focal ships with their cables.

I figured the tip would be hot and the sleeve would be negative/ground? Or is it sleeve and ring? Or just ring?

For the headphone ends you can use TRS plugs as good quality monos are hard to find. The tip as hot and the sleeve as common neg/ground. I did this for my focal clear professionals just recently. Check out this pic.

Just strip the ground/negative back further, solder to the S then take it over and solder to the R too. Basically easy way to bridge the R and S together, ensires it'll work with all 3.5mm headphones, some random models use the R as the ground....

I use Cardas on everything now, no issues whatsoever soldering to the rhodium plated Furutech. Can get the Cardas flux paste too, flux that baby right up.

Quad Cardas is eutectic so it'll stick on anything with flux and heat but they refuse to document the % of silver and it comes with a low melting point so IACS conductivity is most likely very very poor.

Very very poor hey. Strong words.

I think you're worrying about a bunch of nothing. The electronics you're using upstream are all soldered together, more than likely with lead-free SAC305, is that somehow not conductive enough for you?

Cardas refuse to document the exact mix of their quad solder, silver % is most likely very low considering the low melting point so yes, expect 5-10% IACS or so: https://doc.xdevs.com/docs/_Materials/Chemistry/solder_alloy_directory_brochure_97720_r2.pdf

Copper is 100% IACS for that matter: https://www.bluesea.com/resources/108/Electrical_Conductivity_of_Materials/

I'll go screw-in for the RCA sockets, that'll also save from pesky soldering on rhodium plating

14% IACS isn't too bad: https://www.telametal.com/en/cproduct/sac305-fil-soudure/

Thank you both!

Guess the cheap arse poor Cardas or 60/40 solder hooking up all the internal wiring is very very poor too. Real strange to use it. In all high end electronics and all high end cables. Real odd.

Haha. Moon audio uses FedEx. Whatever they do, it comes USA to Australia in a week, no customs etc on top. Might be different in UK.

Then USPS I'd be lucky if it ever arrives. And Royal Mail just takes its Royal time. And its updates go silent for weeks and it suddenly arrives!

I ordered some Senn HD 800 connectors from Moon. I'm ~60 miles from them in NC, and it took 5 days.

Personally for me, anyone but FedEx.

FedEx for Australia!

I have never done this for headphone cabling; however, I feel like it shouldn't be any different.

Hello! I need som guidance here I received a OEAudio's Multi-Plug yesterday that im planning to use it on one of my cables. All my cables is either 4 or 8 core. How do i find out which cable that is R+, R-, L+, L-? The multiplug looks like this:

Do i need to buy myself a multimeter?

Yes, one with continuity functionaltiy...

Or...haha...

Track the cable from the connector alllll the way to the amp end plug haha.

Any good cable boots/splitters?
I’ve seen the via blue ones, but they are kind of expensive at 17 bucks a pop.

Not necessarily. Some cable testers have continuity function and are good for people who just want to work with cables. Cheap ones can be dangerous when you try using them in situations you should not and anyway multimeters can be overwhelming for people.

If you're gonna get into electronics, wait until you know more about what you want.

The Thomann cable tester has a continuity tester, comes with probes, and can help with many standard kinds of cables. Not headphone cables though except for 3,5mm and 1/4 inch.
