Are NBS cables are sound better than Nordost ?

I made some comparisons with NBS Black Label (BL) and Nordost Valhalla and the choice was quite easy. While the Valhalla has some good detail retrieval it lacks completely body and natural weight, also it's color is withish. In the past I owned MIT cables and found them pretty good until I met NBS. MIT cables sound a bit artificial to me(boxes??).
No, the NBS BL is the far best cable I'm aware of.
BTW in Europe there is a special version which called the NBS Active series with an excellent price quality ratio.
Now I understand that NBS is the most copied cable: because it's so good. BTW I heard recently such copied NBS (Heavens Gate Audio) which is derived from the old Statement series. Well it sounded quite bad, very hard and out of balance. So be aware of such brands, they also cost money.

Leon: NBS doesn't make the sound bigger than the real size at all. They just show what the components do. You only have to figure out which series of cable you have to apply, dependent on the quality of your components. Many manufacturers let their components sound too full, just to camouflage their faults, for such you need lean sounding cables. But this way of compensation is not the way I want.
My experience is that I get better sound by using neutral components (getting closer to the music). And with that a portray of life size instruments/voices/space will come automatically. And NBS helps me a lot with that.

It's better to judge the right type of cable depending on the quality of your system. Many people make the mistake that they think the most expensive cable is always the best for their stereo.
The "big" NBS cables and some other serious brands only work when the execution of inner and outer dynamics of your components are extremely well organized.
Otherwise the sound gets too flat or dry and the flow is gone; then the cables are letting you hear too much information.
