Hidiamond Cables, Do these reveal the live show?

@Ozzy, I have noticed my overall volume level has increased. Attributing to the cleaner signal for sure. I really noticed it on my subwoofer, almost 10db's more...Of all the cables owned I never had this experience with the volume increase at all....

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.
