I plug mine into a port on my AV amp too, and power it from a USB port on the TV. This is much better for me, as I only rarely switch the TV input away from the AV amp output, so the input selection process is consistent (and can be named, and displays on the AV amp). It also means the Chromecast is only powered when the TV is on, so if I am using the amp for audio only, it saves a small amount of power (I must get around to measuring it!).
If I use the Chromecast for casting audio only (which I don't do much), I can just plug the USB lead into the adaptor (my AV amp only has a front USB port behind a panel, so that would look messy, and in any case it's currently occupied by one of those tiny cruzer-fit (?) flash memory sticks, with music on it).
