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!

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.
Dayglow; I mentioned TelWire The Reference with a receiver I was using at the time, probably a dis-service to the TelWire guys. I had tried several diffferent cords and could get bass weight (not slam) with some and pretty good definition. Some with bloated bass and limited highs. The Analysis plus silver oval (now called "pro"?) that I was using, has good balance, OK bass, fair separation and no "sparkle" when called upon. The TelWire Reference is a fast cable and gives excellent tight bass slam, very good neutral balance with nice definition. I almost do not want to say neutral because that means muted to some, the TelWire is much more dynamic than that without over doing the transient respnse and still hanging on to decaying notes.

I'm using an Almarro A205a 5 watt tube amp now for music and Parasound 5250 for surround. The Almarro one can never accuse of having bass slam but is more solid at lower freq. and crisper at upper freq.

The neutrality shows up when trying different IC as each one shows it's own characteristics instead of just being brighter/duller etc.

I have not tried the $2500 cords, or $25,000 either but am comfortable with suggesting the TelWire Reference. The mr-cable and Telwire sites not as spiffy as some but fun anyway. Let us know how it works out for you. Mike.
Thanx Mike, and to all that have responded. I just purchased a RSA-Elgar to give my source the cleanest power without overdoing it. Was nearly sold on the Sablon-Gran Corona($850-new) but the cheap Nema plugs brought hesitation. I was unaware of the Tel Wire pc it looks very promising, the Oyaide 004 plugs are a nice touch. Please keep the comments/suggestions coming. Will keep everyone upated!
I've owned the Haley, Duke and Jaco from RSA. RSA makes great PLC's, very powerful and dynamic. Enjoy your Elgar.
