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, I will no disagree that silver presents more clarity and focus, for me though, this comes at the expense of musical weight and bass fundamentals. For every strength there is a weakness. Which is why in most systems I have found silver, in general, to sound clear, and lean. That being said, I have found that pure silver can work very well with speakers or gear that is overly warm sounding. Now I do understand that some place values on musical attributes differently than others, and I have no issues with that. It just helps me when judging the value of others assessments, as obviously no one can try everything that is out there. So I will note that sharpness and clarity is your primary focus, and leave it at that.

In my experiences, it's all a matter of balancing the yin and the yang to one's individual tastes. There is no absolute blueprint to audio nirvana. I currently have some silver in my system as my current cables and cords are varied and involve silver, copper, gold, and even carbon.
Lloydelee21 I cut and pasted the info on the PAD 25th Ann speaker cable which uses the combo of metals silver and copper my mistake...sorry. I see from the web site that the PAD 25th power cord is only silver.
Hi Sksos1...I was wondering where you got that...thanks.

Jmcgrogan2...I hear you! the reason I even experimented with the PAD 25th Ann (pure silver) was because I tried a silver custom cable...and it illuminate my treble...but also lost upper mid and lower treble WEIGHT. I was petrified of what might happen with PAD 25th Ann...I bought demo 'blind' and am delighted to report it carries ALL the weight of the copper Dominus and Ann Contego/Canorus...but with the delineation, clarity of silver...I suppose the network box might have something to do with this? don't know...all I can confirm is I am very very happy I went with this after getting assurances from the dealer that this would be perfectly fine. He was right.
