Everyone of us is a skeptic until we actually try one, then we regret trying them because we now know why people spend so much money on them.
I have no doubt that you believe power cords make a difference and I am not going to debate that. But your claim that it lowers distortion and increased dynamic is misinformation. These are measurable parameter. I have not seen any number or published report on this. If your claim is true, then all medical instruments will be swarming to use these "low distortion" power cord. The impact of this is much greater than an blacker background in audio.
