Thanks, Steve and Guy, for your replies. Yes, I believe experimenting is probably the easiest way (if someone hasn't done it already). The idea came to me at work. I have one of these slim notebook computers with only two USB-C connections, and one of them is also serving as a power supply. I have, however, connected ethernet, HDMI, a USB typ3 for the keyboard and mouse, and a charging cable for my iPhone through one of the all-in-one hub solutions, and it still has a card reader and a few additional empty USB connectors left. All of these are connected to my computer with a single USB-C cable. So a USB-C cable shouldn't have any problem transferring power, ethernet and line signal. I sent an email to B&O, and they told me that the USB-C on BS-Level and BS-Emerge are for powering only, but I don't know about Balance or any other BS speakers. The question is why B&O don't provide a much more elegant solution, provide easier connectivity for the customers and save space on the device, which would make it easier for them to design as well? Anyways, I will order two combined ethernet+USB-C and two line-in + USB-C cables (see the picture) and will update the post once I've managed to test my hypothesis. However, if anyone has already tested this, it would be great to hear about your experiment.
