The Emperor Has No Clothes!!

Differing performance between unwashed vs. washed cars would result from effects of turbulent vs. laminar flow. Which is better: environmentally- and/or behaviorally-dependent. It’s elementary, my dear Watson.

There’s a lesson for how this translates to hifi playback, I just haven’t spent enough to know what it is yet.

Man, I’ve got to stop wandering into bad neighborhoods.

If you believe it sounds better, it will sound better. 

We think we like good music. There is no objective, good music.

Seems there is no shortage of snake oil customers and the flat-Earth movement is growing by the minute. Count me in. 

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.
