What Power Cord can improve clarity and bass slam?

In the last year I sold a lot of silver cables from Audioquest. When I visit clients they also have old cables of cables from other companies. Compared to copper, there is more air around voices and instruments. The become a lot more 3D ( loose from eachother) But Also Audioquest excels in blacks. The appearance of instruments and voices becomes much more clear. In timing and sharpness in individual focus of instruments and voices same story. I am a perfectionist and Always focus on the endresult. Most people are not aware of what is missing. There is missing often too much. I explain my clients the difference between the cables. To hear more information and details is very easy to explain to everyone. I want my clients to get a more complete sound what I call Total Sound.

Regarding the PAD 25th, yes it is silver...but having been a copper fan (all other PADs are copper) for years...I was very very concerned about where this would lead. And it turns out the voicing is EXACTLY what I enjoy about PAD...but the clarity is far greater than its earlier cables. I have not auditioned loads of power cables the way I have other equipment (like digital). But it works and it works well where others have not been as successful. The premium (to me) comes in the fact that it gets the super quiet bit, dark backgrounds and the richness...while somehow providing a lot delineation. In cables, i have found one or the other, not both. Got a demo price, so that helped.

The PAD 25th Ann is actually a combo of copper and silver:
From PAD web site reads the following:
Conductor: Stranded, multi-gauge Silver, single crystal copper
Metals: Copper and Silver
Dielectric: Teflon©
Dampening Material: Ferox (x103)
Gauge (effective): 11 AWG per conductor pair
Current Capacity (DC):
30 A @ 200°C per conductor pair
Resistance: 1.55 mΩ/m per conductor pair

actually, that is not the correct description from the website for the power cable. this is the copy and paste:

Design Goals: Low Noise and High ULTRA Performance
Conductor: 204/60 Stranding
Metals: Silver
Shielding: Ferox 103 plated silver braid 98% coverage
Dielectric: Thermoplastic Elastmer
Gauge (effective): 8 AWG
Current Capacity (DC)
(cable only):
75 A @ 105°C
Overall Product
Current Capacity: 15 A with 15 amp IECC / 20 A with 20
amp IECC
Voltage Rating
(Cable Only): 600 Volts
Resistance: 1.07 mΩ/1M per conductor
Estimated Break-In Time: 125 Hours
Cable Diameter: 1-1/4 Inch
Material Treatment: 5x Cryomag©

@Bo1972, I will no disagree that silver presents more clarity and focus, for me though, this comes at the expense of musical weight and bass fundamentals. For every strength there is a weakness. Which is why in most systems I have found silver, in general, to sound clear, and lean. That being said, I have found that pure silver can work very well with speakers or gear that is overly warm sounding. Now I do understand that some place values on musical attributes differently than others, and I have no issues with that. It just helps me when judging the value of others assessments, as obviously no one can try everything that is out there. So I will note that sharpness and clarity is your primary focus, and leave it at that.

In my experiences, it's all a matter of balancing the yin and the yang to one's individual tastes. There is no absolute blueprint to audio nirvana. I currently have some silver in my system as my current cables and cords are varied and involve silver, copper, gold, and even carbon.
