Flow Ultima Interconnect Cable

Absolute Sound Product of the Year

Direct signal path through continuous silver conductors

The Flow Ultima interconnect employs patented technology where the 6N silver conductor itself becomes the contact, eliminating traditional connector interfaces while carbon fiber shielding and VDM injection control resonance and noise.

Construction

  • Revolutionary patented connector technology where conductor becomes the contact (XLR and banana)
  • Dual-cycle cryogenic treatment on all components
  • Pressure-fit assembly throughout—no solder in signal path
  • Thin contact geometry to minimize skin effect
  • Built-in vibration damping—no external cable elevators needed

Materials

  • RCA contacts are fully annealed, ultra long crystal, 6N high purity silver
  • PEEK polymer dielectric for all connectors—superior mechanical and electrical properties
  • Zirconia ceramic external connector housings
  • Carbon fiber absorptive shielding on all interconnects
  • VDM (Vibration Damping Material) injected throughout cable structure
  • Zero ferrous content—all screws are zirconia ceramic, high-strength polymer, or titanium

The Role of 6N Purity Silver

At the heart of every Argento Extreme Edition cable is a simple conviction: the signal should encounter nothing but the purest possible path. That’s why we use 6N purity silver—99.9999% pure, with exceptionally long crystal structures—for every conductor and every contact point in the chain. This level of purity isn’t a luxury flourish; it’s the foundation for consistent, unbroken signal flow.

In high-end audio, you’ll often see bold claims about “single-crystal” conductors. The truth is more nuanced. While silver can begin as a single crystal, the drawing process required to form a usable conductor inevitably creates microscopic fractures. What actually matters is maximizing crystal length and structural continuity—an engineering goal Argento pursues relentlessly. Our long-crystal 6N silver reduces boundaries that can introduce grain noise, micro-distortion, and tonal irregularities.

Just as critical is what happens at the connectors, the overlooked bottleneck in many premium cables. It makes little sense to feed ultra-pure conductors into brass or copper-alloy terminations, yet this is standard practice throughout the industry. Argento refuses that compromise. Every EE connector—whether spade, XLR pin, RCA contact, or IEC blade—is made from the same annealed 6N silver as the conductors themselves. This creates one continuous metallurgical chain from source to destination, eliminating the mismatches in resistance and energy transfer that often occur at junction points.

Annealing plays a crucial role. By softening the silver rather than leaving it cold-worked and brittle, we achieve higher contact pressure, more stable long-term interfaces, and lower resistance at the physical connection. The result is a more coherent, unrestrained signal—preserving microdetail, dynamics, and tonal integrity without relying on exotic coatings or marketing fantasy.

In the Extreme Edition line, the commitment to pure, long-crystal 6N silver is not an embellishment. It’s the engineering backbone that allows the rest of the design—the VDM insulation, carbon-loaded housings, and custom CNC-machined architecture—to reveal what your system is truly capable of.

VDM: The anti-vibration solution from Argento Audio

Today, virtually all cables use some kind of polymer for insulation because it is very cheap and there is a general belief that as long as the dielectric constant is low, everything is good. Of course there is some truth — but only some — since air does sound better than Teflon and Teflon does sound better than PVC.

VDMTM — short For Vibration Damping Material — is the Argento answer to address two well known yet insufficiently covered problems in cable design.

  • How should a cable be insulated to avoid shorts and corrosion?
  • How can one avoid the small air and structural-born vibrations that affect cable performance?

During our long years of exploration in various solutions, we found that all polymer dielectrics share the same sort of characteristic sound with more or less slightly raised highs and a slight thinness in the midrange. This could to some degree be relieved by choosing copper instead of silver and thicker conductors, but both these “cures” decrease the sound quality in several other ways, making the sound heavy, closed-in and a lot less dynamic.

The conclusion is that none of the usual “solutions” — plastic, air, teflon, composite materials, etc. — were the correct answer to the problem, either because they were simply inoperable or they created other issues when removing the problems caused by the vibrations.

Furthermore, we concluded that the artifacts usually heard in the high frequencies with polymer and air insulated cables were caused both by vibrations and the use of polymers.

The result of this search is VDMTM, a proprietary compound of mixed materials presenting unique elasticity and damping characteristics at room temperature as well as optimal dielectric properties.

Finding an efficient way to apply the VDMTM proved as difficult a task as inventing the material, which we overcame with a multi-stage process involving heating and injecting stages among other technical steps.

As a result of our efforts, we are proud to offer our new VDMTM in every Argento Audio cable, making available to you the true epitome of perfect electrical insulation and mechanical damping.
