Alpha Labs measured the Ultimatum Infinity speaker cable 3m length.
Anas had nothing to gain and all to loose by sending this to Jaap so a brave action and indicates a total belief in his products.
Good results and best conductance Jaap’s ever measured in a speaker cable.

The impact of our cables on the music experience is transformational and we've chosen to undertake this measurement exercise to compare our cables' performance against the top competitors. Our aim is to provide scientific proof that the impact on music quality is backed by science.

Some videos captured during our listening sessions with Jaap from Alpha-Audio. Another joyful experience!

I must agree with Anas and all opinions that favor QSA Lanedri Ultimatum Infinity.
Those are very special speaker cables.
I did comparison between the Speaker cables: Mit Oracle SHD ,Transparent Opus, Siltech Triple Crown, Crystal Da Vinci and QSA Lanedri Ultimatum Infinity.
Spent weeks of careful listening and switching between the cables in my system.
Also asked 2 audio friends for their opinion.
The clear winner was QSA Lanedri Ultimatum Infinity speaker cable.
I am amazed every day by their performance.
Unfortunately I might be temporary forced to sell them due to unexpected reasons.
I will buy them back in a year or two for sure as those are by far the best you can get.
If someone wants them in a good price please PM me. I am not listing them elsewhere yet.
I am in Europe.

We are pleased to share that the Ultimatum Infinity speaker cable has received the "Alpha-Audio Approved" award. The full review will be available soon.
This is fantastic confirmation of what people owning those speaker cables know.
You compare it to anything else and nothing sounds as good.
It's very interesting that you can mesure cable properties and confirm it's sonic performance by how it measures in the lab.
Thanks for sharing
Not exactly and not yet. One can correlate aspects of sonic performance with measurements (or vice-versa), but not nearly all or necessarily the most important.

That is certainly the case for speaker cables. It is easy to show they are dependent the equipment they connected to, to environmental conditions, internal design etc. One of the most important issues is termination. See for example articles 4 to 6 of this series.
Picking and choosing one particular property seems a bit pointless, especially when its impact may be irrelevant given the cable length. The easiest way to optimise a speaker cable is to keep it as short as possible, or remove it completely.
So this cable has fairly regular inductance at 2uH. The Townshend Isolda cable, sold for over 40 years, considers this critical and has inductance of 0.002uH. QSAL capacitance is 200pF, whereas Townshend Isolda capacitance is 3,100pF. If you want low resistance, just get 8 AWG UPOCC cable, it's about £130/m but is about 25mm thick and not very flexible.
Speaker cables do matter, but they are far more part of a system (with amplifier and speaker) than any other type of cable. I've not heard of Alpha Audio, but what is the point of these measurements in isolation?
A couple of months ago, Alpha-Audio conducted an extensive comparison of 32 interconnect cables to understand the differences in their impact. They later carried out a similar exercise with 32 speaker cables. Unfortunately, our QSA Lanedri cables were not included in these tests as we found out too late about it.
Alpha-Audio performed hundreds of tests and concluded that the impact of speaker cables is less auditable than that of interconnect cables.
It was in our to-do list to perform comparison exercises to measure the performance of our cables and compare them against some of the best on the market. We did not hesitate to approach Alpha-Audio for this comparison exercise due to their thorough and objective approach.
During the listening session with Alpha-Audio, and right up until the moment before connecting the Ultimatum Infinity speaker cables, the reviewer Jaap had low expectations regarding their impact. However, immediately after installing the Ultimatum Infinity speaker cables, Jaap affirmed that he has to reconsider his initial thoughts. The transformative impact was undeniable. Some f Jaap's reaction, "Ouuuh...this doesn't need a couple of minutes. Wow, that's a huge difference." "Okay, I have to reconsider the impact of speaker cables. This is nuts, I alwyas tought the impact is okay but this huuuge...other league"

Could you please expand on the router discussion? My router is in a totally different room about 60 feet away from my 2 channel system. Are you saying that I should put an Ult. Infinity there?
I have two more Ult Infinity PC's coming in late August. My plan was to use them on my Aries Cerat Essentia mono amps and then move the Gamma Infinity PCs to my external speaker crossovers. Does it make more sense to put the new cables on my Lucas Audio Music Server and the router which is in another room? How does the Ult. Infinity PC make the router better?

The Ultimatum Infinity power cable has a transformative effect on every component it powers, each power cable elevates the music experience to new heights. With these cables, the law of diminishing returns does not apply; once you experience their impact, there’s no turning back.
To truly understand the magnitude of these cables' effects, I recommend experimenting the Ultimatum Infinity power cables on various components. Based on our experiences, I recommend starting with the router and the server. The impact on the router exceeded our expectations and is at least on par with the impact on the server, impacting both online and offline music experiences.
Can someone explain the science of these measurements? The design of a speaker or amplifier may require, for example, low inductance (Quad ESL) or low capacitance (Gryphon). The inductance and capacitance of this cable is pretty much the same as Belden 5T00UP (total cost $140 - this is the Gamma Infinity cable). The conductivity is allegedly twice as high as the Belden cable. However, signals pass down speaker cables at around half the speed of light for a fairly basic cable, which is about 500,000 times faster than the speed of sound. So any timing differences from propagation or conductivity would be less than the impact of the slightest twitch of your head. Do these Alpha people explain the purpose of their tests anywhere?
Did you ask at the A-A review comments section? They monitor it and respond fairly quickly.
Btw, there's a new fantastic, informative interview/discussion Jaap of A-A does with Ole from System Audio in Denmark, "Measurements vs. Listening." Well worth the 54 minutes.

But we can hear differences much smaller than the slightest twitch of our heads.
Normal listeners can perceive timing differences as small as 10 microseconds. There are some who can even perceive smaller differences. This precision allows us to localize sound very effectively. It also helps us perceive of pitch.
I raise this to point out that without understanding how our ears perceive of sound, it can be difficult to understand which measurement matter and why.
May I ask what "timing differences" are you talking about here?
ssfas I think was talking about timing differences inside of a cable due to different velocities of propagation at different frequencies. Are these the timing differences you are talking about?
10ms is a HUGE difference, IMO/IME. At least to these ears. If I heard that on any component within my rig? That component would be long gone before it even arrived. Jeez.

I was responding to “less than the impact of the slightest twitch of your head” to say that even such little differences can matter given the precision our hearing can resolve. If a sound arrives in as little as 10 microseconds later to our left ear than our right, we can detect that and factor it into exactly where the sound was coming from. Likewise when we hear improvements to our system that help us better pinpoint images in the soundstage it could be that fidelity has improved such that we are better able to perceive the timing differences baked into the recording. Without a good understanding of how our ears perceive sound, it can be difficult to know if small measured differences can matter.
