Experience with NBS Black Label IIIs Power Cable

Can any users share their experience with this cable?  is it better for AMP or Preamp, DAC, CD...

I am looking forward to the responses on your query- gmbt2k.

NBS has been on my radar for awhile now.

At first, I used it on the Hovland HP100.  I don't really like it, maybe it's too new.  I am using it on the power amp now(Burmester 911), about 40-50 hours.  It's getting better. 
Don't expect it to change enough to love it if you do not like it initially.  It will settle in some but I haven't heard any component or cable to change that much.
