Sorry to be redundant but I'm going to emphasize a point made earlier. The bottom line here is how you feel about the speakers. If you are always going to be wondering if your speakers would sound better if they were made in Denmark then there is only one logical choice. Either return the speakers or swap them for the demo pair. We can speculate all day long whether or not the Chinese speakers are the equal of those made in Denmark but the fact is we'll never know. You bought this product for a variety of complex reasons and apparently the manufacturing origin was an important criteria.
If this issue affects your pride of ownership then that is all that matters.
