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?

Most light bulbs including florescents use a.c.
(Led bulbs have a converter inside)
I believe that if you go way back in history, it was determined that it was easier to transmit a.c. over greater distances than d.c.
