The $250 power cables and $600 power strip that dethroned my $10k Shunyata Everest

Hello fellow audiophiles. I've been using products from QSA Lanedri who I believe offer the best price to performance ratio on the market today for their power and signal cables. You may have heard of Quantum Science Audio fuses and might even have some installed in your system. QSA Lanedri have perfected this technology/treatment and are now offering it in their power and signal products. The line of products in particular is called Veridion Discovery which is their most affordable line. I currently own 2 Veridion Discovery power strips (daisy chained), 8 power cables, 3 ethernet cables, 1 DC cable. Initially I was sent a power and ethernet cable to try and was so impressed I ordered more including the power strips. I have been comparing their power cables to much more expensive cables from Audioquest and Furutech. I've also been comparing their power strip to my Shunyata Everest power conditioner and found I prefer the Discovery power strip. Infact I'm in the process of trading in my Shunyata Everest and corresponding Sigma X power cable for either a better integrated amplifier or speakers. Once you pair up Discovery power cables with the Discovery power strip things improve dramatically. Not only does audio improve but picture quality and home cinema improves also and will challenge anything at any price. I will say the Discovery line requires a few days of continuous use or "burn in" period before proper evaluation. I compared their Ethernet cables to the likes of Audioquest Diamond and Wireworld Platinum Starlight 8 and again preferred the Discovery line. Through the Discovery products music sounds cleaner and clearer with a heightened sense of realism. This also applies to film and TV. Compared to the Shunyata Everest picture quality is now cleaner with more vibrant colours. Motion and panning shots are improved with less stutter. I will add that I have the power strips on Auva EQ CSA1 isolation footers. All of my equipment is sitting on Auva EQ footers which I found were better than the Isoacoustic Oreo footers I had previously. The Discovery products look very basic and don't scream high end but from my experience they can go toe to toe with the best at very affordable prices! They offer a 30 day money back guarantee for peace of mind. Definitely worth a look. Cheers.

HMMMMMMMMMMMMMM

A superconductor is a material that can conduct electricity with zero resistance below a specific critical temperature. This property allows an electric current to flow indefinitely without energy loss. These materials also expel magnetic fields, a phenomenon known as the Meissner effect. Examples of applications include powerful magnets in MRI machines, particle accelerators like those at CERN, and high-speed maglev trains. 

 
 
Properties and behavior
 
  • Zero resistance: Below its critical temperature, a superconductor offers no opposition to the flow of direct current (DC) electricity.
  • Electron pairing: In the superconducting state, electrons pair up to form "Cooper pairs" and move through the material in a synchronized way that avoids scattering off the vibrating atoms.
  • Magnetic field expulsion: A superconductor will expel a magnetic field from its interior, a key characteristic that enables magnetic levitation. 
  •  
 
Applications
 
  • Medical imaging: Powerful superconducting magnets are essential for Magnetic Resonance Imaging (MRI) machines to create strong, stable magnetic fields for clear internal body scans.
  • Particle accelerators: Superconducting magnets are used to bend and focus particle beams in high-energy physics experiments, such as those at CERN.
  • High-speed trains: Superconductors can be used to create the powerful magnetic fields needed to levitate trains above their tracks, allowing them to travel at very high speeds with less friction.

So, $5 Monoprice power cords actually superconduct when operated at minus 271C?

But then again, so would Home Depot power cords? 

Fascinating.

I haven’t tested the Ultimatum series personally, but here’s a review with measurements of the 1/0 AWG Ultimatum Infinity power cable.
https://www.alpha-audio.net/review/qsa-lanedri-ultimate-infinity-power-cable/

The playlist I shared earlier captures the impact of adding the Ultimatum Infinity power and speaker cables to the Alpha Audio system.
https://youtube.com/playlist?list=PLmX17B0jgFkcMUEjHFUKueBAVL_SJA8By&si=lAbDNv6-cXNhwM3X

There’s also other reviews covering the Ultimatum Infinity power cable and the 4/0 AWG speaker cables.

If every review and user impression is dismissed, there’s only one path left: try it and see. Anything else isn’t analysis—it’s assumption.

The Ultimatum series may be out of reach for most, but at $250 and with a 30-day refund guarantee, the Discovery Veridion cables make it accessible enough for anyone to test the claims directly.

Whether someone chooses to try those products or not is simply a matter of personal comfort with experimenting in this hobby. However, ridiculing those who do choose to experience a product firsthand only to reinforce one’s own position takes the discussion away from what matters—music and listening. Cheers

Yes, both can become superconductors at extremely low temperatures.
To be fair, there are superconductors that work at much higher temperatures, around -23 C (-9.5 F). But such materials are quite hard to produce (ceramic-like materials, such as copper oxides called cuprates)
High-temperature superconductors are often brittle ceramics, making them difficult to manufacture into practical wires and tapes for industrial applications. 

OSA folks claim to achieve superconductivity 1. for ANY metal 2. at room temperatures.
Makes sense?

This discussion is not only about music and listening.
It is perfectly fine saying "I do like how this magical cable changes my listening experience to the best". And that should be the end of a conversation.

It is not fine (for the "company") to make quite ridiculous claims about superconductivity and difference in sound between 1/0 and 10 AWG wires. Denying the laws of science is not fine.
Cables is not a rocket science. Especially at such low frequencies as audio signals (yes, it is considered a low frequency). No cable can improve physical parameters of your amplifier. Period. Cable can only make it worse. So, pick a right one. A right one does not mean expensive one.
