They may sound and look the same as the Built in Denmark, but you'll always have that little doubt in the back of your mind. Although I would want what I paid for, here is one idea: bring them to the dealer and listen to his and yours side by side, without knowing which one is playing, and pick the one you like best. Have him hook it up to an amp with with an A/B switch.
Also, if he refuses, or hesitates to give you the ones from Denmark, that is a sure sign HE feels there is a difference, whether or not there is one.
