There may be more break in needed with an aluminum tweeter and overall most speakers continue to mature and evolve over the first year or so.
If your using class D power this kind of sound is not that unusual. An expensive approach albeit hard to swallow is to seriously think about a class A power. That isn't cheap but there are some amps that have a bias that produces mainly class A. An even more wild switch and I hope not annoying is to use tube power amps. You may find your audio nirvana that way -honestly it made me stop thinking about any other amps. (well I could be tempted to try some others but...)
Finally if you don't mind using cables as tone controls and I think it is perfectly fine to do so, get warm cables made of copper. I think Cardas has been the best, but the older "golden" this or that were the best at providing full rich sound, don't know the current stuff. I also like Jena labs cables but she's expensive, so I bought used.
Good luck but if you really hate them, just take them back and get the best deal you can for a better speaker for you.
