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!

If you want to hear the true tonality of instruments, lower floor noise, superior dynamics and the feeling of real instruments between your speaker, you should try CH Acoustic X20 power cords. they're unbelievable...
Do the CH Acoustic cords and cables actually sell for their list prices, or is CHA like most other cable companies that offer steep discounts on their list prices? I've never seen a used one for sale, so it's hard to tell.

The reason I ask is because at their list price, there isn't even a conversation as far as I'm concerned. I do own a RSA Dmitri, and would like to try one of these cords, but at anywhere near the list price, I wouldn't bother to waste anyone's time.
Purist Audio is the way to go.......sometimes things in life are that easy....It will do the things you ask for!
My approach is for amps, which draw large amounts of power and current, you want a heavier gauge power cord that is also good quality, essentially a bigger pipeline. Build quality is important for durability and also for connector quality as well mainly.

For digital devices, pre-amps, etc., size of the pipeline is less critical. It becomes much greyer what matters most here, but in general I would go with a mainstream company that has a focus on audio sound quality, but would hesitate to go overboard.

$100-$200 max seems to provide ample choices for both categories based on some recent investigation I have done.

The pwoer cord into my DAC has some wear on it and I woudl like to replace it. I am looking at a Pangea power cord that comes in for under $100 on sale as being a decent bet for both value and quality. No doubt more could be spent but I struggle to have a clear justification for doing that. I have decent but not SOTA power cords on my amps and DAC currently and the sound is already quite top notch I would say. Bass slam can hang with the best reference systems out there I have heard, so the current power cords though nothing out of the ordinary, are doing quite well in that regard in particular.
Any PAD cable but as you go up the line the bass gets deeper and more controlled (as does just about everything else).
