Hidiamond Cables, Do these reveal the live show?

These HiDiamond cables sound interesting. Is there a 30 day offered on them ?
I use Elrod PC's and love them. Can anyone tell me how the HD's compare ? Thank you.

Does anyone know how they compare to Elrod PC's.
I'm using Elrod's and can echo what is being said about the HD PC's with my Elrod's.
I'm all for trying new PC's, but I would like to hear from someone that has compared the two.
Does HD have a 30 day return. If so I would love to try a PC. If they best the Elrod, they would be something special.

The purest produced copper for cables in the world is Furukawa's PCOCC (FACT). BTW, what happened to all the old Hidiamond threads?
