crystal clear audio cable, does anyone know them?

[waddragon]

I am planning to upgrade my power cord cable of the corda opera because after reading some posts in the forum, I know that we can improve the sound of Opera by replacing the power cord.
Luckily I have a coupon from Crystal clear Audio for their Crystal Clear's Signature " Wattgate" Powercord (grey one) with the price 325$ instead of 835$.
Does anyone know about this compary? can their cable improve my Opera?
where can i read their reviews?
and how do they improve the sound?

Looks like some cool stuff. A little overkill IMO

Never heard of them

I have seen their ads on AudiogoN but haven't had any experience with them. I would check out their return policy.

They had a good write-up in the last Absolute Sound

I suggest checking out Zu Audio...american made...reasonable prices...good reviews...60 day return policy...YMMV
