Power Supplies

Electrical noise is everywhere, your best bet of eliminating it without altering your system is the always overlooked, but very useful mains block (also known as the Power Supply).

Your electrical devices not only draw power from the mains, they also have a nasty habit of depositing electrical noise back into it. Why is this a problem? Well, your hi-fi and home cinema equipment is sensitive to this kind of noise, and electrical interference can upset all the hard work you've put into assembling your system.
