I have found cables and power cords to have some impact. The things it impacted was not what I had experience listening for. When I went from a test cable back to my baseline cable, I could tell some slight variances. I would say that ICs are like tone controls. And as has been mentioned, not every component will have the same impact using that IC. Power cords also have an effect on some devices, in particular amps.
The big issue is whether the cost is worth the difference. The vast majority will conclude that no, it's not worth the cost. But taking price out of the equation and having the opportunity to try different setups at your leisure and with your gear is the only way to learn. I certainly wouldn't spend my money trying to find out. But if you get an opportunity to try some different items, it's worth trying for your own peace of mind. If the article or review has financial implications, keep that in mind. If a hobbyist is giving their experience and it's like a component upgrade, they are embellishing their purchase. But there are a lot of us that have found a difference worth change that don't have a bias other than liking the sound better. For those who need empirical data to tell them what to do or how to spend their money, buy a radio shack set and let live. Superman was a comic book character and couldn't save the planet, don't try.
The differences you hear is most likely a phycological effect, I know because I've been there, try conducting some fair blind-testing yourself and you'd see what I mean.
Either that or you have superhuman hearing abilities that I don't have.
Power cables? Don't even get me started until you've re-cabled everything from your regional power plant all the way to your home and change all of the infrastructures in between. Incase you don't know, power companies don't use OFC or silver to make their cables, nor are the cables in your house or what ever you live in (Unless you've already re-cabled them.)

1. What is the theory that supports this will have an audible effect?
2. Did you do any blind testing to ensure you were level matching and eliminating bias? Or were you able to measure the signal changes (not just the impedance) to see if there were measurable differences?
LOL, do keep in mind that cable capacitances are actually VERY small (in the magnitude of 1-10pF), This is smaller than the high-frequency filter capacitors used in amplifiers to remove unwanted supersonic frequencies and prevent oscillation in the amplifier (these capacitors are in the magnitude of around 100pF).
Yes the theory and fair blind-testing results are very important if you're trying to prove something here, the phycological effects plays a large role in our listening experience.
