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!

see what I mean Nick_sr, they are not kidding, this post is in regards to my last post for you, cheers.
@Audiolabyrinth, I am not suggesting that all expensive power cords are over priced. What I am saying is that I find it hard to believe that spending $10k on a power cord will provide the biggest bang for your buck for improving the sound.

As an example say you own an amp that is worth $10k and your not entirely satisfied with the sound you look at all the alternatives and you have determined that an upgraded amp would cost 5k more than what you have. Alternatively you could spend say 1k on power cable that would provide a similar benefit. Clearly the 1k power cord would be your best choice.

Now assume the cord cost 10x as much, clearly upgrading the amp becomes the better option.

Assuming my first scenario holds in general, then $10k power cords would only be sold to people owning $100K amplifiers. But now you must ask the question, if you pay $100k for an amp that amp must provide the absolute sound! If a power cord, $10k or $1K, can further improve the sound then where is the value in the amp?

Basically, in the cost is no object domain, when you buy a piece of gear it should be the absolute best and provide the absolute sound, the manufacturer should be tasked on finding every optimal sub component of the unit, be it power cords, power supplies, caps, resistors, whatever as long as it is optimal. If this is not the case then in my humble opinion something is wrong.
My focus is Always on the endresuls. Expensive cables you sell by doing a-b blind comparison. When the Nordost Valhalla came out, it went crazy. I could live only from selling these cables for a long time. It was that convincing. People bought less expensive sources with a Valhalla. Just by doing a-b blind tests. Every person whants the best result for they money they want to spend.
Budburma-I'm just enjoying the banter! The 2 HiDiamond P3's I just purchased have made substantial improvements. When I upgrade my electronics/speakers a HiDiamond P4 will be at the top of my list.
Hi Nick,

Your points are well taken. Insanely/"stupidly" priced power cords are NOT the first port of call imho. Sure, they'll make a difference...but is that where you put your money first? In my particular case, I am blessed to have a CJ GAT which I got demo...the hospital grade cable is far better than most 3rd party cables I have tried. But it WAS better with a 2nd hand PAD Dominus cable I picked up for a few hundred bucks.

When the ENTIRE system had been totally isolated (all 9 components including speakers), all cables on 'my list' had been bought...THEN, I came across a friend's silver power cable and tried it on my CJ GAT. yes, it illuminated the treble in a way I had not ever considered before...but it also shaved the treble/mids in a way I did not like.

That got me thinking...and after nearly a year, I came across a well-priced PAD 25th Ann PC, and got it, as a 'final touch' where after 7 long years of searching for each piece of my Dream List one piece at a time...I finally have my Dream System assembled. So, I guess I am generally agreeing...this kind of cable is not really first up on the list...but as a final touch, it has made a tremendously positive difference, and I really like it. IMHO.
