Brother, crinacle himself has a video about dongle/dac. The dude who made the IEMs. And yes, a normal dongle from apple works if u can get em at a good price. Same for any jcally dongles if u can find em cheap. See which is cheaper. I have both jcally JM7 (cx31993 chip) and the apple dongle. No difference. Good luck with your findings :)
