I’d run a couple of dedicated 15 or 20amp 120v circuits into the room and call it a day.
Since I have no power in the media room at the moment ... I’m running everything off a single 15A circuit and haven’t blown any thing yet. It’s a lot more stuff then your talking about. The reason I can get away with it is that my power needs are mainly dynamic. I turn on the amps and subs one at a time and play it at reasonable levels. The dynamic power comes from the stored Power in each amp

In theory you can get twice the power into the room with 220 per circuit but you’re creating headaches for your self.
