When did you ever hear a system sound so life-like

Breuninger,
I can identify with the mbl's. To my ears they are one of the few best speakers with proper setup.
The only other speaker up there next to the mbl's are the wilson x2 alexandria, totally believable!
I feel that playing the system while sitting in an adjacent room could easily fool me at times.

Ok I believe those that claim it is impossible.
But wouldn't it be interesting to get a top notch system and have it set up on a stage next to live musicians and do an a/b test between live and recorded playback.
How many can claim they will definitely tell the difference, I would love to partake in that experiment.
Not writing this to pose a challenge but as a learning step.
