I second what the previous two members said, and add the following:
The best power cord for audiophile purposes will be the best conductor of low frequencies and the best impediment to high frequencies, without restricting dynamics. Stock power cables are not very good in either respect. Indeed, I don't know any stock power cord that features any sort of high frequency rejection or attenuation. High frequency attenuation is important simply because the high frequencies that travel along power cords into your gear are the most invasive of frequencies: they are perhaps the most limiting factor to system performance. So, even if expensive gear comes with a basic power cable, these other reasons existÂindependently of whether expensive equipment comes with cheap power cordsÂto investigate the effectiveness of power cords.
Perhaps I'm mistaken, but audiophiles generally accept that the quality of our gear's power supply has a significant impact on the end result of what we hear. For that reason alone, a serious music listener ought investigate the significance of the power cord. After all, as Robert Harley says (and others I'm sure), "from the gear's perspective, the power cord is the first six feet, not the last" (paraphrased). That is just to say that, despite it being at the end of hundreds of miles of electrical wiring, to the gear in question, the power cable is the most important wiring of it all.
