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!

Dayglow,

Def a big fan of PAD and Sablon Gran Corona. Use only these two throughout my system. Good luck.
Lloydelee21-Almost purchased a new Gran Corona but the cheap Nema plug on a $850 pc doesn't seem right? With the PAD I wasn't sure which cord is the best value due to so many cords in their product line. If you could comment on the strengths and weaknesses of both cords it would be much appreciated.
Hi Dayglow,

Speak with Mark Coles about the SA...i would think he would do a different termination for you if you wish. The PAD Dominus is (for me) the sweet spot in the range. Second hand they run about the same as a SA Gran Corona. The PAD gives my systems a quieter, richer and more seductive appeal without 'adding' to the sound ostensibly. Its just like i went to higher quality camera to take a color picture...hence got deeper color saturation. The GC is exceptionally quiet,giving my system clear, natural, extended sound, not quite as rich...sometimes a good thing.

Perhaps you've come to this realization(or not) already, but one way to at least partially achieve your goal could be looking for powercords based on solid-core wires, believing them in general to entail many, if not all of your sought-after qualities to "improve clarity in complex passages, add bass slam/definition and create a more open/liquid presentation without giving up speed-resolution and neutrality ..." Where I've tried solid-core powercords in my setup - in different configurations and wire diameter, etc. - in all cases they've provided a more calm, liquid, and resolved sound. Bass seems notably more tight and yet weightier, subjetively deeper, and more aperiodic. Mids appear more physical, relaxed, and a "shouty" and thinnish tedency has been eradicated(at least over my speakers and compared to the different multi-strand alternatives I've tried); highs are more finely structured and not least more clean sounding. Overall the immediate sonic impression of these qualities reveals a slightly varmer, more full and relaxed sound.

Is your system (star-)grounded? Grounding my system, especially my poweramp(NuForce Stereo 8.5V3), lead in particular to a better bass respons - much like above impressions of the solid-core powercords.

Oh, I'd also pay attention to the powercord(if you haven't already) from the wall outlet to your powerstrip/-distributor. Using solidcore-based wires here has a definate, and positive effect in the same vein as well.
The kinds of differences you guys are talking about require changing gear, not cables. I think I'm "almost" with Bryon.
