So what type of cable do you use after the adapter? Would a regular USB-C work? The new iPad Mini with USB-C works with the M2 and an apple USB-C, but I need more portability.
Part of me wonders if this is just cable and or hardware lottery, several other users report success. @HTML @againa how are your LT-LT1cables? No noise?
Yes just a normal USB-C cable C to C in your case. ddHiFi TC05 is very nice and comes in two lengths and straight or L connectors, I use a longer straight one for iFi Gryphon desktop but for portable the short ones might be better for you.
I don’t have that Fiio cable, I no longer have any Fiio cables. After early bad experiences with Fiio cables simply not working with other devices outside of their own I don’t even look at them now.
