I don’t see any technical benefit of this cable construction for this application.

The reason is that it looks cool so people who don’t understand anything else will pay for it.
So does he have mini pylons that he strings them across so that they don’t touch like they do now?
Definitely not sound-related for a power cord. A wider spaced transmission line with air in it, which at an estimated length of 2 m is so electrically short as to be completely irrelevant for the 6000 km free-space wavelength of the 50 Hz mains.
Obviously this help to stop RFI pickup but makes RF pickup easier. Also makes the cable more easily radiate electrical field, magnetic field and RF to nearby cables than traditional mains cables.
Making sure you get as much differential-mode coupling as you can from your home AC mains so the 60Hz hum is maximized at the equipment power input.
Who would want to twists cables.
On the technical characteristics having air between wires means lower capacitance and higher inductance than traditional wires closely each other. If you want to optimize power cable, you would want low resistance and low inductance – and even somewhat high capacitance does not hurt (may even be beneficial as filters high frequencies). The design show in the picture is pretty much opposite of that technically optimal cable.

Thanks for breaking down the actual physics instead of the marketing hype!

The electricity travels through miles of unregulated power cables, transformers, distribution stations, juntion boxes etc, but the last 2 feet of audiophile cable will magically solve all issues… Yeah right…
Tomi Engdahl says:
Wires inside walls are part of a building’s electrical system, designed to safely deliver power from the breaker box to outlets and fixtures using specialized, sheathed cables like Romex.
Sheathed Cables: Modern homes use non-metallic (NM) sheathed cables, commonly known by the brand name Romex.
The cables are designed to carry specific amperage loads, with 14-gauge wire for 15-amp circuits and 12-gauge for 20-amp circuits.

Power Ground: This essential connection links the amplifier securely to the main power supply ground. By doing so, it provides not only a crucial safety path for electrical current but also ensures that any excess or stray current is safely directed away from sensitive components, protecting both the device and the user from potential electrical hazards. This connection is vital for the stable and reliable operation of the amplifier.
Signal Ground: Serving as the fundamental reference point for audio signals, the signal ground plays an indispensable role in the fidelity of sound reproduction. By maintaining a consistent baseline, it ensures that audio signals are transmitted clearly, devoid of unwanted noise or interference. This clarity of transmission is pivotal for delivering high-quality, noise-free sound to listeners.
Star Ground & Spar Ground: These terms refer to specific and carefully designed grounding techniques employed within the amplifier circuit. The star ground method involves creating a single, centralized ground point, which minimizes the potential for loop interference and noise pollution. On the other hand, the spar ground method—involving a distributed grounding scheme—equally aims to reduce noise by strategically placing multiple grounding points. Both techniques are meticulously implemented with the objective of minimizing noise and interference, thus optimizing the audio quality and performance of the amplifier.
Power Amplifier Board: Often described as the heart of an amplifier system, this central component is where audio signals are boosted to the necessary levels for driving speakers or other output devices. Proper grounding of the power amplifier board is paramount to ensuring stable operation. Without effective grounding, the amplified signals could become distorted, leading to undesirable audio performance. Consequently, meticulous attention to grounding is essential for maintaining the integrity and quality of the amplification process.

Tomi Engdahl I’ve built a lot of walls of many different kinds. Concrete, gypsum and various types of wood materials, both industrial and private buildings, and I have never seen any other kind than non-metallic sheathed cables with different gauges inside pvc tubes. I can’t see any reason to plug any cables better or thicker than those inside the walls into the socket for the last few feet, because a chain is never stronger than the weakest part.
Tomi Engdahl says:
Geir Atle Løken I see no point in going thicker than what is used inside wall. Also no point in some special cable construction. For few meters long power cable only thing that has made in some cases difference has been shielding on the power cable – shielded power cable can reduce the noise coupling from mains wiring to nearby signal cables. In some situations there has been difference in background noise level that can be heard and measured (alternative method to reduce noise pickup cam be better shielded signal cable or more distance between cables)
Tomi Engdahl says:
What is the claimed benefit of this monster power cable? It seems to be in every way worse than traditional power cable in all relevant performance features.
Tomi Engdahl …starting with standards compliance! Your insurers will forsake you.

Someone’s compensating his screwed up DNA-helix.
Tomi Engdahl says:
Utter nonsense, to me, but if someone is willing to pay for it then why not?
Are these cables safe? I mean, there are standards power cables have to comply to. Are they rated for the mains voltage? What about the earth connection?….
do any of these companies ever show sample level analyses of what happens to a test signal with / without the emporers clothes on? thats the wild thing about this stuff – we have complete information
i suppose the retort is ‘hahaha you’ve just outed yourself as an amateur by even suggesting polluting my signal chain with an AD converter’

Tomi Engdahl I totally agree. If the signal cables are shielded, I can’t see any advantages with special power cables at all. And I have seen the prices on some of those cables…
Walter Franken exactly. Then the speaker manufacturers uses bell wire from the terminals to the drivers. It’s the audio equivalent of Steven seagal……… bullshido!!
Walter – If nothing else, inside those big, expensive black boxes are PC board traces, usually. Or, thin wire in an output transformer. Heroics in the last 3 meters is a bit silly.
