Most audio power supplies do not draw sinusoidal current from the AC. The supply circuit impedance converts power supply current into a noise voltage. This noise voltage can have a very broad frequency spectrum. Any other audio components on the same circuit see this noise, and may not be able to filter it effectively with their power supplies.
Passive power conditioners that provide as much isolation as separate dedicated lines have to use series inductance with at least some of the outlets, and this can affect performance. Active conditioners are quite a bit more expensive than typical AC circuit installation costs, even with top-notch outlets.
