What speakers can b considered as world reference?

As audiophiles, we know that only live concerts can be considered as the true point of reference. We strive to get our systems to sound like the real thing and acoustical instruments are probably the best examples. But with the advancement of technology we are seeing better tranducers from familiar names and not so familiar. What could be considered as reference speakers today.
In my experience, the fantastic control room in Focus Recording Copenhagen, is a world reference. The custom monitoring designed by Ole Lund Christensen simply makes a mockery of every high end setup I have ever heard, including those costing three hundred thousand dollars for a stereo system.
