The most simplistic view of AC power is binary — it works or it doesn’t. Your blow dryer or toaster gets AC from the outlet and powers up or it doesn’t, and you let your hair air dry or eat something else with your tea. But this black-or-white view of AC power doesn’t encompass sensitive audio gear, whose performance is greatly affected by the quality of the power it receives.
