What Power Cord can improve clarity and bass slam?


My price limit is around $1K new or used. The new pc would be plugged into a dedicated line(12-gauge Romex)using an Oyaide DX/WPC-Z wallplate. My amp is a Valve Audio Predator/Mullard CV-2493-Northstar Sapphire CDP and Focus Audio FS8 speakers. Cables are JPS Labs-Superconductor Q/Plus. I would be replacing an Opera Audio Ella Baby pc on the Predator. Want to improve clarity in complex passages, add bass slam/definition and create a more open/liquid presentation without giving up speed-resolution and neutrality which are my systems strengths. After many hours of research here is a list of power cords that could work.
Cable Research Labs-MK 2
DH Labs-Red Wave
JPS Labs-Kaptovator
Silver Circle Audio-Vesuvius
Stealth Audio-Cloude 99
VooDoo Cables-Black Diamond Dragon
Your comments regarding these power cords would be appreciated along with any other suggestions. Look forward to your responses!

@ Bo1972, whatever!, I know your last post is YOUR opinion, I know for fact Taralabs has a better performing mid-band than any P.A.D. cable.

Hahahahaha....how did I know this was coming Audiolabyrinth?! This post also is YOUR opinion. Face it, there are no FACTS when it comes to the best performing cable. It's ALL subjective opinions. Oh the irony is delicious. LOL!
@ Audiolabyrinth; hahahahahahaha....very funny11 Good to hear you are still alive!! I did not compare your powercable with the PAD. I cannot Judge, but the PAD are extreemly good in all the different parts you Judge a powercable for.
LOL!

No power cord over the stock UL approved one.

Clarity and bass slam are due to the amp alone.

$1000 for a cord is BS!
Hi John, I never said what is best, I said their is an uncanny mid-band that is really magical about Taralabs cables, The new cables are available over the next few weeks,It's funny that no cable company has the equipment or the know how to make a cable like the Taralabs Evolution Grand Master to have the Frequency of a 32 gauge conductor and still be 000 gauge speaker cables!, By all means, this is the all time referance in cables!
