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!

Yes, the K-S Emotion will also provide more bass weight, as will Virtual Dynamics power cords, if you can find them used, as Virtual Dynamics is out of business. One word of warning on the Virtual Dynamics cords, they present a very large soundstage (height and width), but rather flat and two dimensional. Some folks love that front row excitement, others, like me, prefer a smaller, but more 3-D stage. The K-S and PAD do this very well.
When I tried different power cords in my system most robbed me of "bass slam" - quieting the noise floor but also diminishing dynamics. Only ones that let true punch come thru in my system were Audience. Energy is drippig off every note.
Hello Dayglow,

I know this is over your budget but the Nordost Valhalla is well worth it and is exactly what you're looking for.

The Valhalla P.C.'s will improve your system in all the ways you're seeking and probably more than you thought possible! You should be able to get them used slightly over your budget. Good luck.

best,
Tom
Stealth V10 Preamp cord did this in my system am also using Stealth V10 speaker wire.
I'd second the recommendation for the older Elrod's...putting the EPS-3 Sig on my mccormack dna1 amp was like strapping on a supercharger.
