Hi everyone. Get my oldfashioned ER4S with pretty nice custom cable (2*4*250 cores cooper Litz). I'm using DX150 as source. Player has balanced 2,5 mm out, so i want replace 3,5 jack to 2,5.

So i asked a local service about it and they advice me a Ranko Acoustic rep 1050 jack. With work and discount it cost 36$. Will i get some ptofit from this jack, or better take some folklorical Oiyade jack in 5 times cheaper?

I like the rhodium Oiyade jacks in the moon audio silver dragon and black dragon cables I have for my Fostex 900 (silver dragon direct-hacked by moon audio), black dragon for my Utopias, silver dragon v1 iem for Massdrop/NuForce EDC3, and silver dragon v3 for the Astell&Kern/Jerry Harvey Audio Layla 2s. In general, I think the rhodium sounds better than the gold plating, but that could be because the gold plating is usually with a molded plastic plug.

I do not have experience with that particular Ranko Acoustic item. You may want to contact Drew Baird at moon-audio.com to see if he has any ideas. He may be able to give you some other options and a different quote. Hope this helps.

Thanks a lot. Will write him for more info. Before this days, i never hear about rhodium jacks, so i little bit curious about this thing.

Probably. At 2.5mm, corrosion, surface wear and plug connectivity become extremely important. The contact surface on a 2.5mm plug is very, very small. Think of a square spring pressing against a round surface. Ultimately, it's like a tangent line drawn on a circle. The actual contact point is almost a singularity in two dimensions. Long-term, this means a lot of scratching in your audio, and eventually drop-outs.

If you have to use a 2.5mm connection, then everything you can do to prevent it from corroding or suffering surface wear is what you want - gold, rhodium, whatever. I am no expert on the materials, but gold is best for corrosion. I believe rhodium adds surface wear resistance as well (gold is obviously a soft metal).

Thank you for reply! I decide to take Ranko plug. I gonna leave those headphones in use for a long time, so durability is importent thing. I cannot find any same jacks at Aliexpress (2,5mm, brass shell, platinum/rhodium plating), so price for Ranko in local service center is normal. At ebay i found same offer, but only for jack, without work.

After all, i will post few photo and first impression.
