Vibration Control

A simple placement of a hand on a breaker box will illustrate how much vibration can be caused by the flow of electricity.  Vibration is one of the largest issues in electricity, and as a result we focus on it a lot. Scientifically speaking, energy and matter are neither lost nor gained, but only change form. When an electrical signal enters a wire, it is met by resistance. To overcome this resistance, work is required. The products of the work are heat and vibration, converted from the energy of the original signal. Therefore, at the other end of the wire you are left with only the amount of electrical signal that was not lost to these byproducts of the work demanded. The breaker box may be an exaggeration of what can happen within a cable, but NVS Sound has still found that any means taken to reduce vibration results in a large increase in fidelity, especially in clarity, size of the soundstage, and accuracy of timbres.

  • Specially designed chambers are filled with unique powders that control vibration and even provide some RF and EMI shielding, while still maintaining flexibility. Different powders are used in each product series, and it is these powders that attribute to the weight of the cable.
  • The entry level powder used by the Copper 3S and FDV series weighs 7.3g/cc and is designed to pack very tightly. This powder brings greater separation between instruments, and better timbres than a non-treated conductor, as well as having shielding properties that help lower the noise floor.
  • The 2 series powder is non spheroidal, and has a particulate range from 12-44 microns in size.. Weighing only slightly heavier at 7.8g/cc, many of this powder’s advantages come in the ability to pack much denser into smaller crevices, allowing even more control over the conductor. The resulting sound is more neutral with increased differentiation of instrument timbres between like instruments (such as an E b clarinet and soprano saxophone, or horn and trombone), bigger soundstage and more inner details.
  • The 1 series powder is specially designed and formulated to pack tight and dense. Weighing over 12.8g/cc, in application it’s specially designed shape shows it’s prowess as when compared directly to the 2 series power, it weighs twice as much! In addition, it has unique shielding properties, shielding into the X-ray frequency range! The result is an increased soundstage, increased clarity of timbres and details, more immediate dynamics, and better bass performance while also allowing unimpeded treble extension.
  • The Inspire Series powder marks a departure from the increased particulate weight as the main form of vibration control. The Inspire powder took many years and over 27 elements in a special formulation that deals with shielding more comprehensively, and absorbs vibration away from the conductors instead of controlling them with mass differential. Due to it’s unique properties, it is also incredibly difficult to inject into the cables, taking over 15 times as long to fill a cable! The Inspire powder has an extremely smooth and emotional presentation.
  • “S” powder technology. The ‘S’ stands for stacked, and the premise is simple. The Inspire powder was so impressive that NVS experimented with a small application of the powder into every cable series. It turned out that applying just a little bit of powder at the end of any Series of cables brought a little of the magic of Inspire to each cable at only a slight cost increase. The Inspire ‘S’ series actually uses 1 series powder at the start of the cable, as that combination brought some dynamic contrast that a full Inspire cable seemed to lose.
  • ‘V’ powder technology was found while searching for a USB cable solution. Digital signals are very easily influenced, and we found that none of the previously formulated powders performed perfectly in this application. The Inspire powder did the best, and we re-engineered it until the results were in line with the usual expectations of NVS Sound. Due to it’s ability to pack into a tighter space, we were able to create the FDV Series, which exhibits incredible speed and spaciousness.

Conductors

NVS Sound started by using specially provided conductors, but over the years and through many experiments, found that there wasn’t anything on the market that had all the attributes combined into one assembly that NVS was happy with.  Having developed relationships in various industries over the years, NVS Sound was able to use multiple suppliers to create the most musical, least obtrusive-to-the-sound conductor.  From the drawing to the annealing process, the exact size of the conductors, whether there are multiple sizes (introduced phase shift vs. single size conductor bundles), braided to a specific PIC instead of twisted, thickness of cold drawn Teflon, and a decreased time of processing from conductor drawing to dielectric extrusion, all these things contribute to make the NVS Sound conductors unique.  Many cable companies would have been content only with these conductors as a final product, but of course, even with all of this technology, NVS Sound found that the powder technology still positively affected these incredible conductors.  Total AWG size was also found to be better modulated by adding or subtracting solid wires from the braid, not by changing the wire size.
