Taking a Balanced View

It is fair to say that most hi-fi enthusiasts have paid little attention to the importance of their mains power supply and in part this is because of their ignorance of the impact of less than ideal supply wiring and of the various types of noise that creep into equipment via the mains plug. But, says Stan Curtis, L|A readers need make no apology as most of the amplifier designers he is aware of take a great deal of care in the design of everything after the IEC power socket - yet seem to assume that their equipment will be fed from a perfect supply direct from the power station turbines. This obviously is not the case, but Stan has some solutions to make it almost as if it is the case.
