No worries.
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
On page 13, IBasso showed the proper plug you need to run coaxial. Moon Audio can make you a custom coaxial cable that will work. Just send them that picture. It should be a standard 4pole 3.5mm plug.
