Audioquest cables?

I am the owner of a pair Audioquest Midnight speakercables, but I am looking for better sound from my Dynaudios and I think I could get this with another speakercable. I think the Midnight is to soft in the bass, More control and fastness is what I need.

I tryed Nordost, but it´s to metallic and analytic to my Dynaudios. But then I think: couldnt I just buy a more expensive and newer Audioquest speakercable?

Have anyone heard the diffrences between old and unexpensive Audioquest cables, and new and more expensive Audioquest cables? Or maybe just experiences with new Audioquest cables?
