Hidiamond Cables, Do these reveal the live show?


Just wondering if the people that own any of these simply amazing HiDiamond cables can explain the characteristics and why/how they seem to create the live experience like no other cable has. THX in advance for sharing your thoughts....

Owners and reviewers of the KCI Silkwood plus cables are equally impressed and enthusiastic - at almost half the price the KCIs sound very attractive - anybody compared Hd and KCI ?
I would like to add, since I have a complete loom of HD Cables (except for the Speaker cables) I believe the overall volume has increased.
That is, the settings on my Pass Labs Preamp are now lower than I used to use before the HD cables. I'm attributing this to the cleaner signal being transmitted.

Has anyone else noticed that the volume level has increased once the HD cables have been added?
Can owners/distributor answer: Is there a trial period/or alternatively any place in the Northeast USA to audition them? (I am in Connecticut)
