Synergistic element copper good for power amp?

I;ve seen tungston mentioned in a few high end acables and it puzzles me because

• copper is a better conductor - OCC copper even better
• using a metal that does not conduct as well as copper would
  • degrade dymanic performance
  • degrade clarity, which in turn impacts imaging

Is it used to "tame" overly bright systems?

Personally I use OCC copper or silver (for interconnects) and love the dynamics and details they bring to my sysem. I cannot see using a cable to downgrade the characteristics of a system

Any thoughts?

Grover Huffman Pharoah power cables really upped the sonics of my JC1 monoblocks.  Highly recommended.

Just to give an update.  I bought the Element copper, but unfortunately, it is not a good match on my monoblocks in my system.  However, they works well on my CD, streamer and DAC.  I will keep using my PS audio AC12 for now.  The next I want to try is something similar to the AudioQuest Thunder.  

Most of the Synergistic Research power cable lines have a 10ga for amps and a 12ga version for components.
