There are some cable manufacturers who tell their customers that a thick, heavy gauge power cord is unnecessary. And some cable manufacturers even espouse that an audio-grade power cord should not have any effect on the sound of a component. How strange! At VooDoo Cable, our priority is to design and build power cords with the best sonic performance possible at that price point. We believe the power cord is the foundation of the cable network in any system.
Power cord design is a complex balance of conductor line capacitance and inductance using all the dielectric materials and conductor alloys available to achieve the desired dynamic control and tonal balance. Most importantly, a well designed audio-grade power cord should act as a filter to suppress unwanted line noise without constricting the flow of AC to the component. The larger gauge conductor will provide ample amount of line capacitance to the component, which allows the transformer inside the component to operate efficiently and quietly, without interference from eddy currents, and other forms of line noise. When plugged into a high-current power amplifier, a well-designed power cord will allow the transformer to operate at a cooler temperature. Over the years, we have heard from many customers who told us their amps seem to run cooler after they upgraded to one of our power cords.
Some high-end cable manufacturers make skinny light gauge power cords, while others make thick heavier gauge power cords. Some high-end cable manufacturers use copper braid shielding to protect the conductors from EMI and RFI, while others don’t. Some high-end cable manufacturers use thicker dielectric insulation that is matched to the charge of the conductor winding, and others don’t. Some high-end cable manufacturers use the minimum cable construction to lower the profile and manufacturing cost of the power cord, while others use a beefier cable construction to maximize the sonic performance of the power cord. These design specs and dielectric materials add to the size and thickness of the power cord. Take a look at the profile of premium, high-performance power cords from the best cable companies, and you will see that thick power cord design trumps thin power cord design when high-end audio performance is the goal.
