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

I haven’t tested the Ultimatum series personally, but here’s a review with measurements of the 1/0 AWG Ultimatum 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.

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.

Although your job was to convince people to pay $250 for $5 Monoprice power cords and you seem to have largely failed, you have valiantly tried (and continue to, though hopefully not for much longer).

All efforts deserve reward, and to be fair QSA should indeed sell you an Ultimatum cable (what an idiotic name though!) for like $10 - just so you can keep claiming with a straight face that you pay for product with your own money.

@ionna22, exactly.  I have no problem with someone thinking that their $5 cable sprinkled with fairy dust sounds better than my Shunyata Omega speaker cables.  All good.  But I have a big problem with the magical claims by the company about how sprinkling some magical fairy dust turns regular metal into a SUPERCONDUCTOR.  One is personal opinion, and that is fine, and the other is fraudulent marketing BS that is not fine at all.  Reminds me of the magical record clamp made of magical ebony from the "ancient swamps of Africa" for $4,000 that apparently makes your vinyl system transport you to a live concert.
