Synergistic Research Element Copper vs Tungsten


Anyone tried both the speaker cables and the ICs? What will make a bigger difference, Tungsten speaker cable over Copper or Tungsten IC over Copper?
It seems like many folks found the Tesla Precision Ref speaker cable a big step up from the Accelerator, far more than the equivalent IC upgrade. The same with the Element series?

I have a specially ordered Tungsten audio cable from my new a Sony 830 TV split into L-R rca ends running into my Arcam A39 amp.  Speakers cables are also Tungsten into my 6.1e Genesis tower speakers.  No longer use my subwoofer.  Soundstage is wide, deep, smooth, very easy in the ears.  Copper can be a bit grating.
