Double blind test- over a month- could this be a reliable test for any equipment?

Blind tests are in reality almost never performed. I hate to judge these things too critically but it appears blind tests are primarily a ploy by naysayers and pseudo skeptics to try to argue their case that such and such cable or tweak must be bogus. “I bet it won’t pass a double blind test.”

I think one should first determine whether they prefer tube or SS; which would of course be sighted, and then go from there.

I would never go double blind because I'd want to know every detail about whatever it is I'm trying to decide on.
