Me too.Is there a standard in these tests as to how long you listen to one set of equipment before switching, say 2 minutes or 3 minutes? I ask because sometimes when I've done non-blind comparisons, I've heard something over longer time spans (say 5-10 minutes) that I missed in shorter intervals. Difficult to tell whether this is more imagination than anything else though, in that if you're trying to notice difference, you/your brain will likely find it, whether it exists or not?
It could be, because it is sighted, we stress ourselves to hear the differences, and what do you know! we will.
May well be powers of persuasion.
