I've participated with several blind wine tastings, knowing what the line up was going into it. It was very sobering picking a $25 bottle over a $300 bottle as being "better", when I thought for sure I would be able to pick the high dollar bottle. When you no longer know what your are drinking, the playing field is leveled. I suspect the same can be said for auditioning speakers blind. Haven't tried it, but sure would like to.
