I agree utility companies do install a demand meter for large users of electrical power.

I would also agree any inductor that would be used across the mains for an audio system would not be enough to cause any problem.

Problem with too much inductive reactance, heat..... It can cause feeders and panel boards to run hot. This in turn can causes fuses to blow even though the load may be below the rating of the fuse. Same is true for breakers. The electrical wire as well as the terminations temperatures will run above their normal temperatures and sometimes be very hot.... And in this case capacitors are added to bring the lagging out of phase current back in phase with the voltage. Thus PF correction. Problem? Motor Frequency Drives hate capacitor banks...
