Personally, I would love to be able to take part in a fair double blind comparison. I do believe double blind tests are by far the best way to get at the truth of our own perceptions.
But to be effective in approaching that truth, I would want the comparison to be between amps I am already familiar with and which I already believe sound different. What I want to find out is if my perceptions are to be trusted.
Even though I hear, for instance, my Plinius amp as sounding identifiably different from, for instance, the Bedini of identical power it replaced, I am never certain that the differences I believe I hear are not mental constructs of the non-blinded situation combined with my own mental processes.
The program material must be familiar, also. All this is because the hypothesis being tested is: The Plinius 100 sounds identifiably unlike the Bedini Classic 100. That is the premise on which I am basing my purchase choices.
As a sworn skeptic, I want some better evidence of these phenomena than personal testimony or my own perceptions.
Using familiar gear, rather than strangers, means I have a ready yardstick by which to measure my results. I don't care what Richard Clark thinks. I just want to come closer to knowing whether I am fooling myself. After all, a lot of money is at stake: the thousands I spend on "better" equipment.
Setting up a double blind test in one's own room would be the ideal for this kind of experiment. Now that i have thought of this, I will perhaps try somehow to set one up. Obviously, if I do not score well, I will feel the test has exposed my prior self-deception. But, if I do well, I really will not be sure of anything because a really solid double blind test is pretty much impossible in my house.
Program material, also, would need to be familiar, for the same reasons.
