The equipment reviewers at Stereo Review and I believe, High Fidelity, also became convinced that a lot of differences they thought they identified with sighted listening disappeared with level-matched blind listening. There are many others. I am not alone in this, by any means.
In his debate with John Atkinson, Arny Krueger notes that training will increase the ability of a person to detect differences in a DBT. John Atkinson agrees. jj agreed with that. E-stat agrees.

And, the more transparent system you use, the deeper into the recording you will hear and differences among components will be more readily observed. Just like any other activity:
It wasn't until I became a more accomplished ice skater and got Reidell Comp 925 boots that I could discern differences between John Wilson vs. MK blades. The MK Phantom provided better support taking off and landing jumps. Riding deep edges was a snap. I no longer had trouble with Camel spins.
It wasn't until I got a Honda S2000 capable of neutral 0.9G cornering that I could readily tell the difference between a truly high performance tire like the OEM Bridgestone S02s and lesser tires with which I experimented. The S02s (also supplied to various Ferrari and Porsche models) offered higher levels of adhesion and better road feel.
It wasn't until I had the chance to shoot a neighbor's highly modified rifle (comp trigger, floating target barrel, etc.) that I appreciated that the particular bullet and loading greatly affected long range (400-600 yd) accuracy.
The examples you give show an improvement in performance, in you skating, in your driving, in your ability to hit the target.
Now, a change in equipment may increase your enjoyment temporarily or long term.
A DBT may determine whether you actually can detect a difference in the sound of your system due to the change in the equipment.

Category Error. Tests produce data. Well conducted tests produce evidence. Neither determines anything. People make determinations.

That proves it is a test of the listener's critical listening/test taking skills and invalidates it a scientific test of audio component differences.
In real scientific DBTs, does training the subject change the result of new drug clinical trials?
Laughable.
"That proves it is a test of the listener's critical listening/test taking skills and invalidates it a scientific test of audio component differences."
Well, well, now, I see the source of the confusion. Whoever said that an audio DBT was a test of audio component differences?

That would be you fewer than thirty minutes after asking that question!

Reading comprehension is not your strongest point. Let's look again at what I wrote.
"A DBT may determine whether you actually can detect a difference in the sound of your system due to the change in the equipment."
Where does it say the test is of the differences in equipment? It doesn't. We already know there is a difference in the equipment, and one need not even turn it on to know that. With reasonably accurate measuring equipment, one could doubt measure the performance of each piece and compare the differences.
As Tony Lauck has pointed out, a DBT provides data, and people determine whether the person doing the DBT can detect a difference from the sound alone. Saying that a DBT does it is a linguistic short cut.
The issue is whether the person doing the DBT can detect the difference from the sound alone.

Read again the second and third sentences. Aloud, if necessary.
In particular, pay attention to words found in both sentences!
'Differences' and 'differences one can detect from the sound alone' are not the same thing. As I said, reading comprehension is not your strong point. Neither is good will, I would guess.

After listening to it again, my original feeling remains unchanged... which is that the mindset of those who have heard it remains as unchanged as mine. I think both sides chose the "winner" that corresponds to their POV.
But thanks for posting anyway - it was interesting to hear that again.
