I do agree that this test seems to be the most valid and honest method of blind testing. It's too bad we can't simply test as we would pictures of colors with slight differences, holding them up and rapidly flipping our eyes from one picture to the other.

Gross differences such as turntable example should indeed be picked up by rapid fire blind testing. Subtle differences might not, IMHO.
I'd be interested to see any test that has been passed whether it is long term or short term. I think that your original post had a question about whether people have failed a gross difference test so I included my observations about my TTs.

The problem with the Audio Lab is that it is www.audioreview.com's thread purgatory. When the mods don't want a particular line of reasoning, off it goes to the Lab. That's probably why you don't get as many replies as when you post to HT or speakers or even the cables forum.
