NBS Signature or Fim Gold Interconnects

I don't know about the Signature line. I use the NBS Statement and FIM Gold interconnects along with Nordost Valhalla. In my opinion the FIM are a touch darker and slower than the NBS and Nordost. The NBS and Nordost are almost interchangable in my system. In that the Signature is a lower class interconnect from NBS I would asume the FIM will be a step up in detail, imaging and treble extension.
If you want specific thoughts please write me, I'd be happy to share more.
