No worries.no I haven't tried this, I accidentally saw that you can order this coaxial cable for Ibasso D16 and PB5
The point is Ibasso isn't offering an official product that is approved to work with DC Elite and though I found myself an (unstable)'workaround I am just waiting for someone confirming that some standard product like your suggestion is working perfectly and not like in my case with some cheap 3rd party 4 pole Adapter half stable as the plug is too long for example
