Can you explain what poles of articulation are?
Multipole Technology - MIT Cables - Music Interface Technologies
MIT Cables’ core audio cable technology is our exclusive Poles of Articulation, named after the fact that every audio cable has a single point where it is most
efficient at
storing and
transporting energy. At this point in the audio frequency spectrum, the cable will articulate best, and represents the cables’ particular Articulation Pole.
Theoretically, if you could use three different cables at the same time, each with a different Articulation Pole, to interconnect two audio components together, you would have an interface with three Articulation Poles; one for the highs, one for the mids, and one for the lows. Together, they would work to transport the audio signal from component to component with more articulation. This is what MIT Cables accomplishes with its patented technology, to a much greater extent, within each engineered interface. We call this Multipole Technology.
The benefit is more lifelike vocals and instruments, mid and high frequencies become less bright or tiring, voices are clear and understandable, and bass frequencies become tight and deep.

Can you explain the concept of “poles of articulation”?
A pole of articulation can be thought of as a pole that is holding up a tent in the center.
The tent will have a slope or skirt associated with it on both sides of the pole. Electrically, a pole has a magnitude and it stores energy. How much energy the pole stores is determined by the size of the storage elements—linear capacitors and inductors. Capacitors store voltage for a period of time and return that voltage back to the cable or network. Inductors store current for a period of time and return that current back to the cable or network. If the capacitor or inductor is larger it will store more energy. An articulation pole stores energy and then over a predetermined amount of time can deliver energy to the load.
All cables have one articulation pole, the point where it is most efficient at transporting energy, which is usually around 1500Hz. This is why most cables sound OK at about 1.5kHz but sound brighter at high frequencies and muddy at low frequencies. With just a single articulation pole the first few harmonics of middle C and A are not correct with regard to timbre, and won’t image properly. We end up with an articulation response in conventional cables that is shaped almost like a bell. The highest point in the bell-shaped curve is the highest articulation frequency of the cable, again, about 1.5kHz. We add more poles of articulation above and below that frequency by adding additional capacitive and inductive elements to produce a straight-line articulation response. The first technology we invented that helped overcome these issues was our MIT 2C3D Technology. I wrote a paper about this in 1991 called “Transportable Power in Audio Cables and Energy Storage Elements.”
Going back to our Jitter Free Analog technology, the new version of that, JFA-2, is the primary reason the Articulation Control Consoles are so sonically superior to the Oracle products before them. The Articulation Control Consoles also use a very improved 2C3D technology, which also helps imaging and soundstaging within the very important frequency range of 80–800Hz.
