You just plug them in and that's it - no problem. It's a well defined standard and you can put a lot of power through it - that's what the PD standard is which the OP was talking about (although it won't work on this amp as it requires AC). You can connect a 4k monitor to a laptop and power the laptop from the monitor via USB-C. It's great. A lot of connectors support different standards - you can plug two devices into a monitor via HDMI, for example, and discover one of them only updates at 30hz in 4k mode - nice. Standardizing on USB-C at least allows for consolidation of all these other sockets into just USB-C allowing cable reuse and ideally one standard to bind them, although I'm sure cheapskate manufacturers will screw that up as usual by cutting corners to save costs, be first to market etc.I read somewhere that the USB-C connectors are very finicky. Keep in mind that USB-C is just the form factor and there are a bunch of different standards jammed into that unified port connector. It's probably possible to implement with some time, but I don't think it's worth the effort for most smaller/mid-sized companies to spend that time on it when they could be improving more substantial aspects of their products.
