Siltech Triple Crown Power Cable


Siltech’s mono-crystal silver conductors already deliver the highest resolution, lowest loss audio signal path. But alongside new levels of musicalnuance, detail and definition, their astonishing accuracy also reveals the shortcomings in other aspects of cable construction, residual levels of micro-distortion and other error mechanisms that have been masked until now. Using the latest advances in audio measurement techniques, it became clear that to eliminate all distortion and minimize all induced errors would require the mechanical and electrical optimization of the signal transmission path as a whole, including not just the cable but the connectors as well. It would require a completely new construction, new levels of geometrical and conductive consistency. It would demand a complete rethink…

The result is Triple Crown – a cable with a revolutionary new construction and revolutionary new connectors that revolutionizes the musical accuracy of audio cables in the high-end audio market.

Cable performance isn’t just about technical parameters and LCR values measured in the lab – because most audio cables aren’t used in labs. What Siltech’s exhaustive empirical research has revealed is that it’s not just low LCR numbers that matter, but the consistency with which a cable delivers those numbers under real-world conditions. In many ways, that is no surprise, given the proven benefits of conductor quality and consistency and spaced shield construction. What is a surprise is just how critical it can be – and how it throws development emphasis onto mechanical and electrical stability.

The essence of power cables

Power cables have an unexpected big audible effect on the reproduction of music. All too often these effects are negative ones and simply degrade your music. But how do power cables cause such audible degradations? Magnetic leakages cause distortion in particular frequency ranges, these are picked up by all connected electronics and other (interconnect) cables nearby and as such induce small distorted currents which are unrelated to the music but do effect it. Furthermore, those distorted currents can be very high and cause saturation in many power cords resulting into audible distortion at these peak currents. These currents cause harmonics at multiples of the mains frequency.The strongest effect is from 100/120Hz-450/500Hz harmonics.

Siltech top engineers have much experience with 3D magnetic field analysis and use dedicated programs to visualize leaking fields. To develop the Triple Crown power cables, very advanced Multiphysics software (COMSOLtm) and measuring equipment by FW Bell (3D Gauss) and Audio Precision (THD) was used. FW Bell ultra-sensitive gauss meters are used in the development of hard-disk magnetic heads and therefor ideal to help reach our goals. These goals are the extreme high levels of power integrity, leading to an astonishing subjective performance. The elimination of harshness, complete lack of induced distortion and subsequent bass stability create a new ultra-realistic feel to the music.

The Triple Crown power cable’s special grounding even removes the need for ground lifting, often done by audiophiles to improve the sound. A one-stop product for digital, analog, tube or semiconductor equipment? Digital amplifiers or amplifiers with switch mode power supplies have very different effects than electronics with analog power supplies.

Tube power amplifiers often use a choke coil in their power supply and have yet other needs. The Siltech Triple Crown cable is balanced for both switching (digital) and non-switching (analog) loads which means that over a very large operating area magnetic interference with other nearby cables or electronics is minimized over an extreme wide frequency and current range. To make a universal flawless power cable, the EMC suppression and stability under load has to be suitable for every purpose, low or very high power, digital and analog. We believe we have achieved the goal set by our high engineering standards.


But first, let’s consider conductors: Our mono-crystal silver conductors already set the standard against which all other conductors are measured. How could we improve on them? Well, if mono-crystal silver is the best conductor material available, one way to get better performance is to use more of it, creating dimensionally optimized conductors that use more of this costly material. The Triple Crown’s conductors are the largest diameter mono-crystal silver conductors we’ve ever used, a solution that’s only possible in a genuinely cost-no-object design, where the only consideration is ultimate performance.


We know how effective the widely spaced screens used in our Double Crown cables are when it comes to protecting the fragile audio signal. We also know how much damage, soft, lossy insulation materials can do. That means that the best audio performance will come from a cable that is large diameter and stiff – almost like a length of pipe! The challenge seems impossible: to create a large diameter cable that is also rigid yet practical, structurally stable yet flexible.

Siltech’s engineers have finally perfected a radical new cable topology, a complex construction that ensures absolute geometrical and mechanical consistency, no matter how the cable is curved. It needed to be longitudinally flexible but stiff in compression. Designing it was a challenge, but nothing prepared us for the difficulty of actually producing it. Two years later, it is finally ready for launch, delivering results that far exceed even our expectations. We call the new topology Air Cradle Construction and it combines massive mono-crystal silver conductors with ultra low-density insulation created from a complex Teflon matrix, to deliver incredibly low inductance, resistance and capacitance. The result is a vanishingly low loss cable with numbers that aren’t just better than any other cable we’ve ever produced – they’re better under any circumstances.


Passing signal through cable is one thing – passing it through connectors is quite another. Such is the superiority of the new Siltech cable that it ruthlessly exposes the limitations and inconsistency of existing plugs, making it necessary to design completely new terminations, connectors that share the same design goals of mechanical and electrical consistency and stability as the Triple Crown cables. Not surprisingly, the new Triple Crown connectors are just as radical as the cable they match. Their solid mono-crystal silver contacts provide perfect material continuity through the cable and connector, while the revolutionary two-part asymmetrical design of both the XLR and RCA self-centres and mechanically clamps the contacts, ensuring a geometrical and electrically consistent connection, no matter the size or tolerance of the socket. Despite their size the new connectors are also incredibly low-mass a result of the intricate construction and watch-like precision. That should come as no surprise. We had to work with a watch-maker to achieve the tolerances we demanded.

Superior Shielding And Easier Handling

The large break-out bodies at each end of the cable are for more than mere decoration. Each one has a switch on it that allows you to lift the shield connection, allowing you to choose between directional or star grounding of the shields – or no shield grounding at all – depending on the system and environmental situation. It’s another small but surprisingly important step in the pursuit of ultimate system optimization.

Each plug also allows the connector to turn through 90 degrees (so 180 degrees per cable). The Triple Crown cables are necessarily bulky and stiff. We made them as flexible as possible, but we couldn’t make them bend any more easily without compromising the sound. Pose-able connectors aren’t just an aid to installation – they’re what makes it possible. 

Was it all worth it? No one number tells the whole story but consider this – at 18pF/m, the Triple Crown cable has around one-fifth the capacitance of our already outstanding Double Crown.
