Every audiophile who tried with better power connections has heard about their performance. The improvement can indeed be dramatic, moving a system typically from good to great. Simple resistance is the most significant characteristic of an amplifier cord. Other elements like capacity, inductance, and protection are not sufficiently noise-reducing and do not influences even the most revealing audio systems.
The quality of the connectors is vital for power amplifiers as well as other equipment but reliability and resistance are the reasons for this. Good quality with every aspect of the system is a prerequisite for any decent system. The high price does not guarantee decent quality. Importantly, well-designed devices do not need any specific power cords or even power conditions. Well-designed appliances filter and control internal power for the appliance to function properly even on distorted and noisy Audiophile Power Cables, in addition to brownouts or blackouts. Going out of the grid is an unnecessary task with high sound quality equipment.
Generic power cables generate audibly difficulties and this is why a thoroughly designed cord can improve the reproduction of music. The fact is that component power supplies are faulty and allow power line Noise to blend with music is the reason for sound variations from Audiophile Cables. Shielding cords help since external interference can be eliminated and the capacitive filtration increased, but there are still other audible difficulties. Triboelectric noise is a static loading or discharge effect when drivers touch the insulation. This noise varies drastically in magnitude and frequency depending on the isolation materials used in the cord.
