Power Cord For Audio Research gear

Jadem6: My brilliant whats? What are you talking about?

Whatever that means, Gmorris. Whatever.

You're right that cable is a medium, but it's for transporting AC AND/OR DC. Not necessarily both. In fact, rarely both, unless it's a phantom powering arrangement.

Stevemj: Thanks for the common sense approach. A further deficiency of Jon Risch's "explanation" that Kevperro posted is that Risch assumes that the conduction angle in the primary of a power amp's peak-rectification power supply will remain the same at heavy current demand as at light current demand, and thus he divides the RMS current demand by the conduction angle to come up with an absurdly high peak current figure. In reality, the conduction angle increases as the current demand rises, and thus the peak current rises to only about 50% to 100% above the RMS level. That still points to the need for good power conductors to minimize power loss, but they can be had for a fraction of what the boutique power cords sell for. Power cords that sell for $50, $100, $500 or whatever serve the ego and not the audio.

No_money, you're missing the point. The important thing is not "don't listen," but "know how to listen." Understand what makes a difference in sound and what doesn't. Make direct listening comparisons, preferably properly set-up double-blind or AB-X. Understand that a listening test is not a test of your hearing, but of the sound of the equipment. Therefore, "finding" differences that don't exist is no more valid than ignoring differences that do. Understand the principals of psychoacoustics so you can better know your own conscious or subconscious listening biases and how to minimize them. The more you understand about the workings of audio, the easier it will be to make your system sound better by investing in what works and avoiding pouring money into what doesn't.
