What headphones do you want to drive with it? Is your USB-C source a phone or computer?I would instead just want a simple USB-C to 3.5 dac adapter for those situations.
Here's one that has been discussed on head-fi: https://www.head-fi.org/threads/hidizs-sonata-hd-dac-cable-new-tiny-and-mighty-dac-amp.880478/Thank you both. It is from my phone, yes. I have a portable amp already, so what I was interested in was just the bare minimum cable with usb-c to 3.5mm with a decent dac for when I want to travel without the amp. I have several different headphones, but e.g. the MrSpeaker Aeon (closed back) is getting much use lately.
