Ruby Crown Jumper (Set of 4)

Ruby Crown Jumpers
This unique loudspeaker cable features Siltech’s latest S10 monocrystal silver conductors in star quad configuration combined with wide-range shielding. Both SSP009 spades or WBT 0610 Ag banana connectors are available.

Ruby Crown
As one of the world’s leading hi-fi cable manufacturers, the success that Siltech now enjoys did not happen overnight. It’s the result of forty years of intensive research and development into our own proprietary metallurgies and technologies, by the most gifted engineers and with the most advanced measuring equipment; a never-ending journey to become better and better, and create even more unique experiences.

To commemorate this milestone in our rich history, we have created the new Ruby Crown. It’s a dedicated all-analog cable range comprising RCA and XLR interconnects, loudspeaker cables and power cords. It marks our ruby anniversary, celebrating four decades of designing and manufacturing world-class cables. The name also echoes some of the most beloved products in our long history, like the Ruby Hill and Ruby Mountain.

Celebrating 40 years of excellence
40 years after producing its first cable in 1983, Siltech launched this exceptional series to commemorate that pioneering event. This new series is the least expensive route to our finest ever metallurgy, the newest S10 monocrystal silver conductors which have been specially configured in a 3- or 4-core design tailored for this application, with high-grade connectors to further improve performance.

S10 Monocrystal Silver
Our newest S10 Monocrystal Silver is the pinnacle of our cable design and manufacturing. The Single continuous crystal metallurgy eliminates boundaries for the lowest possible distortion. Its increased conductivity - up to 112% of regular silver wire - Leads to an extremely low-loss conductor for a lower noise floor and higher power handling.

By using proprietary sophisticated annealing processes, we produced larger and more consistent crystal structures, reducing the discontinuities in the signal path. The result is exceptional openness, detail, and musicality - perfect for the world's finest hi-fi systems.

To the best of our knowledge, Siltech’s S10 Monocrystal Silver is the finest audio cable conductor ever developed. We don’t say this lightly, as it is the product of many decades of intensive research and development, now arriving at our 10th generation of silver metallurgy. Our dedicated listening team, and many music lovers around the world with us, think it delivers a musical performance without equal.

Material science
The type of conductor used is central to the performance of an audio cable. Various materials have been tried over the years, from copper to carbon fibre, silver, gold, or combinations of them. These all have their own characteristics which have a fundamental effect on sound quality. But it isn’t just about what material you choose; it also depends greatly on the production technique used to make it.

Looking under a microscope, you’ll see that metal is a lattice or matrix constructed from individual atoms, which is imperfectly constructed from multiple large crystals, all locked together. Between those crystals are boundaries and voids – barriers that any signal passing through the metal must cross.

These interruptions and discontinuities in the conductors don’t show up via empirical measurement techniques, but subjective listening can detect them all too clearly.

Because human hearing is a primary defence mechanism that’s capable of discerning the distance and direction of any potential threat, it is incredibly sensitive to any disturbance in the patterns and natural structure of noises all around us.

So, while our auditory system might not have been designed specifically to appreciate recorded music, it is astonishingly capable of analysing and appreciating the complex shapes, patterns, and structures in a musical performance – and recognising any distortions or deviations that afflict them.

Monocrystal Silver
Siltech (short for SILver TECHnology) has become famous for its silver metallurgy used in its cables and even in loudspeakers and electronics. Siltech’s first invention – back in 1997 – to solve the problem of these crystal voids of natural silver was its proprietary Silver-Gold alloy, now having reached the ninth generation G9. It fills those tiny gaps inside the crystal structure with pure gold, leading to a more accurate and enjoyable sound than any other type of silver.  Although filling in these microscopic cracks brings huge sonic benefits, it cannot match a conductor where those voids are entirely eliminated in the first place.

Siltech S10 Monocrystal Silver
Siltech’s continuous single silver crystal metallurgy completely eliminates microcracks, giving the lowest possible resistance and distortion.

Developing our own specialist, audio-specific measurement techniques, Siltech was able to detect and evaluate the impact of the barriers and voids within conductor materials, and identify the myriad of micro distortions they produce. This lets us set about reducing the damage that they cause to the audio signal passing through our cables. This approach went way beyond simply selecting the raw conductor material.

Using sophisticated annealing processes, adjusting both the temperature and rate at which our conductors are drawn and how long they take to cool, we were able to produce larger and more consistent crystal structures, reducing the barriers and discontinuities in the signal path.

While many manufacturers have worked with what’s commonly called ‘long crystal’ or ‘monocrystal’ copper, Siltech combined this technology with our superlative quality silver to produce our groundbreaking Monocrystal Silver cables. Not only does it reduce distortion, but our monocrystal silver wire also has a conductivity of 106% to even 112% of regular silver wire, leading to an extremely detailed, transparent, and homogeneous sound.

Absolute performance
As they feature the most expensive raw materials and are hugely time-consuming to produce, you will only find Monocrystal Silver conductors in Siltech’s premium and flagship products, with Crown in their name – Our 35 Years Anniversary Crown Prince series and the flagship Royal Crown Series (including our top-of-the-line Royal Triple Crown).

When absolute performance counts, cost or effort cannot be a concern. Indeed, the very existence of these products shows Siltech’s commitment to advancing the science and art of sound.
