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!

You should just borrow cords and see which has the best synergy with your system. The best cord I used on my VAC Phi 200 tube amp was a Fusion Audio Enchanter. Great bass weight, slightly warm sounding. WyWyres also delivers awesome bass. Both companies offer trials. I would not commit to pay $1K for a power cord I have not demo'd...too much hit or miss involved
I don't want to be a killjoy, but I think you should consider whether a $1K power cord is the best use of your funds, especially when you consider that your speakers are $3K, your amp is $3K, and your source is $2.5K.

To be clear, I'm NOT criticizing your equipment, which from what I can tell, is well designed and well regarded. I'm merely suggesting that there are other ways to allocate your resources that may be more likely to yield the results you're looking for.

I'm not trying to ignite a debate about whether expensive power cords are effective or worth the money. I've owned several power cords that are more than $1K, and numerous power cords that are considerably less expensive. So I'm not merely speculating when I say that the improvements I've heard from expensive (and highly regarded) power cords are smaller than the improvements I've heard from other tweaks, many of which can affect the specific characteristics you mentioned in the OP, namely "bass slam," "openness," and "liquidity." For example, you could...

1. Install better Romex for your dedicated line. For example, VH Audio's 10 gauge cryo'd Romex. IME, this can improve the system's "bass slam."

2. Change the balance of shielded and unshielded cables. In my system, the best results were achieved from shielded power cords and shielded digital interconnects, but unshielded analog interconnects and unshielded speaker cables. That may not be the best approach for your system, but IME, finding the right balance between shielded and unshielded cables can improve the system's "openness."

3. Reduce the effects of EMI and RFI in the system. There are a great number of ways to accomplish this, many of which are discussed in this thread. IME, reducing EMI/RFI can improve the system's "liquidity."

There are more approaches to achieving the results you mentioned. Happy to discuss if you're interested. If, however, you want to stick with a new power cord, then feel free to ignore this post. You should of course spend your money however you like.

I second the comments by Bryon and MCondon.

Also, I would point out that your amplifier is described as using minimal filter capacitance in its power supply, the theory being that that will allow for faster recovery following high demands for current. That is the opposite of the philosophy that most high end amps adhere to, which is to maximize filter capacitance, so that (oversimplifying slightly) there will be less depletion to recover from.

That is one reason (among many other more general reasons) that I would not expect a high degree of consistency between the sonic characteristics that are reported for specific power cords in other systems, and the effects they would have in your system.

I third the comments...i went from standard to dedicateds.It was the best upgrade ive done by far.everythings improved,550.00 for install was the best money spent!
Assuming your power may not be clean to start with, which is often the case, I would first try a suitable power conditioner to accomplish your goals before investing in a fancy power cord. THere is a good chance that will accomplish your goal and you would then find that different power cords make little or no difference as long as what you use has basic quality construction.

I say this because power conditioners are much better suited to effectively address any power issues at play than power cords.

Different power cords might result in a difference in sound as well in any case, but are much less well suited as the best place to address power issues in general.
