I have a very limited knowledge of electrical engineering that almost entirely revolves around music equipment. From everything that I’ve seen, music equipment ends up converting the AC power to DC power right at the power entry point (or at least soon after). It appears they’re converting AC power to a higher voltage and current DC power. Is the only real advantage of AC power to pump more power over a line to where devices will then manipulate it to what they need in DC? Are there any common household items that actually fully operate off of AC power or does everything convert to DC at some point?

To give you the simplest possible answer, it is much easier to transmit A/C over long distances.
So, if you want to create a national power grid to supply a whole country then A/C is the way.
If you used DC then you would need boosters all over the place to keep the signal strong and useable.
