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!

Jtimothya,

Talk about a very thoughtful observation, your penultimate paragraph, especially, expressed what seems to me to be a very thoughtful observation. I've always thought the transduction processes are the most critical to audio quality, with the role of the speaker and its interaction with the amp being paramount.

db, I agree that transduction process is critical, but I would say that the speaker/room interaction is even higher paramount than amp/speaker....IMHO.

Jtimothya, I agree with much of what you say, I would only add that I think we all use cables/cords as band aids to some extent. Yes, obviously having great equipment comes before cables, but sometimes, even equipment from the same manufacturer doesn't hit the sweet spot for us. Sure, we could try 20-40-60-100 different preamps (speakers, amps, etc) in our system to find the one that is just right, but most of us only get to try a dozen or so at best. We then use cables that help to make our system sound it's best. Are we looking for a bit more speed and resolution? Are we looking for more dynamics and power? There are many different flavors to try, but from my experiences, two general directions.

I have played around with a lot of gear and cables over the years, and generally, as far as tonality is concerned, you have the warmer, richer, powerful end of the spectrum and then, on the opposite end you have the speed, resolution and articulation end of the spectrum. I have heard very powerful bass slam, but it tends to come from equipment/cables that are on the warmer, powerful end of the spectrum. What most feel of as bass slam (weight) tends to actually be an emphasized bass and lower midrange. Emphasized by the fact that the note hangs longer or is slower in speed.

I don't wish to get too long winded, but yes, I find that bass 'slam' and bass 'definition' are mutually exclusive. Just as one cannot get hotter and colder at the same time, one cannot get faster and slower at the same time. I've heard a lot of gear and cords, but I have not heard anything that I would say has great bass weight and bass resolution, you sacrifice one to get the other. Of course this is just in my own personal experiences. YMMV.

Cheers,
John
