Remember everyone, it's perfectly possible to have a civil discussion about this. That being said, I find it extrememely difficult to wrap my brain around the idea that a fatter power cable can make your system sound better. It screams of self-fulfufilling marketing BS.

Keep in mind that I'm not saying those who did hear differences are deaf and dumb. I'm just saying it makes no sense to me whatsoever. And the differences you've heard should easily show up in tests where equipment is connected to measuring devices.
