Flat speaker cables like the ones Nordost makes tend to be the cables people go to when they want to brighten things up. In a sytem that tends to be very warm or laid back sounding this helps a lot to make things more lively.
For me Analysis Plus cables accentuated the low end way to much in my system. I needed Nordost to show me how cables are suppose to disappear and make it seem as if the speakers were attached directly to the power amps outputs :-)
