If you are convinced you can hear a difference under normal listening conditions, that's one thing. If you can show there's a measurable difference that is well established to be enough to be detectable, that's a more interesting thing. If you can repeatedly convince others who are skeptical that you can hear a difference under normal conditions that is unmeasurable or measurable but well established to be inaudible, then that's a VERY interesting thing.
Interesting things sometimes happen. VERY interesting things are extremely rare, and science and knowledge moves forward when we encounter those and investigate.
