Blind tests don't necessarily give a good idea of what is better, only what is different between what's being compared. Something that sounds better initially, blind test or not, might not sound so good over time. I've found that to be true on many occasions.
As I understand it a blind test is not to determine which is better, but rather can you distinguish a difference which usually needs to proved statistically that there is a significant difference.
