Anyone with experience having cables made using Amorphous Metals/Alloys

@bugredmachine thanks for your reply. It's good to see your response kind of validating my hunt for Amorphous metal. So did you sell the Indra now that you have balanced pre? I know these kind of cables are crazy expensive, something which I will never spend my money on.

Strange coincidence but a pair of stealth audio indra's just showed up in the classifieds!

5K for a 5m RCA interconnect pair. The same seller is also selling a pair of Sakra interconnects - 5K for a 1.75 m. The Sakra's are Stealth Audio's top of the line cable.

@srinisr saw those listings...too much of money for me to try amorphous metal. Maybe someone else with deeper pocket can snag it.

@audio_phool - RE...

So have you measured the capcitance of same conductor (of same lenght, geometry, width/diameter, thickness) with different dielectric used as insulation material. I thnk thats what is making the audible differences.

Turns out, the Dieletric Constanct (Dk) of the insulation has little to do with the capacitance of the cable. The capacitance of the cable is measured between the signal conductor and the neutal conductor and is governed more by cable geometry, (e.g. number of conductors, space betwen conductors etc...)

• so, the capaciance of the cable can impact sound quality by impacting the magnitude of impacted frequncies within the audble frequency range
  • e.g. more Treble or Middle or Bass
• whereas the Dielectric Constant of the insulation governs how much noise is generated within the cable itself
  • i.e. as the signal alternates from +ve to -ve, the insulation is charged in one direction and then charged in the other direction. The switching to and fro causes noise that imapcts the signal being conveyed and reduces clarity and details
  • so clarity and details can be improved by using an insulation having a lower Dk value

I have measured the capacitance of my interconnect cable with each change in insulation material and there was little to no change in the value of its capacitance.

• certainly not enoungh to impact treble and bass response
• But the improvement in clarity and details was easy to discern as the value of DK of the insulation was reduced

Hope that makes sense? - Yep, I also had to research this aspect of cable design because I initially thought the Dk of the insulation on a wire would impact cable capacitance, but my measurements did not support those thoughts.

@williewonka Thank you for your response. I am actually intrigued by the mechanism and it's explanation of how dielectric can affect the conductivity. I would like to know about your thoughts on how dielectric induces noise in the signal, a more indepth discussion. Feel free to PM me if you think this is not the appropriate forum to discuss it.
