Dana Cable Design Approach

There are many design considerations in building speaker cables. Cable manufacturers make different technology choices in designing their unique brand of cables. Some seek exotic material claimed to be more effective in carrying signals. Some may choose active solutions designed to change the characteristics of the signal. Others use material science techniques such as cryogenics to alter the characteristics of the cables. Yet it is important to recognize that cables are inherently passive components whose main role should be to allow signals to flow more freely. Active cables seek to add characteristics to the sound, a job we believe is best left to other active components such as amplifiers. Being passive, cables should not add characteristics to the signal but they can impede the free flow of the signal. In this role, cables cannot improve the sound but can certainly degrade it. A poorly-designed cable can make reproduced music sound veiled and lifeless. The best cable would be no cable at all, but wireless signal transport has its limitations and is currently not suitable for high-quality amplifier-to-speaker signal transport.

A speaker cable is a passive device. It has three electrical attributes - resistance (R), inductance (L), and capacitance (C). An ideal speaker cable would have no resistance, no inductance and no capacitance (zero R, L, and C). Not physically possible, but if it were, this cable would “do no harm”. It would simply pass the amplifier voltage/current to the speaker without changing it in any way. All real world speaker cables have some R, L, and C. The value and ratio of these three parameters affect the “sound” of the cable, from “favoring the bass”, to “smoothing the high end”, to “bringing out the midrange”, etc. The goal of DanaCable™ is to “get out of the way” and to cause no audible effects. It allows the amplifier and speakers to do their jobs as intended.

In designing DanaCable™, we choose to get back to basics instead of going exotic in our approach. While others seek new, but often un-proven, materials, we strongly believe that when it comes to cables, more copper is better. Take a look at our DanaCable test video clip above and you’ll learn why low resistance is so crucial to the amplifier-speaker interface. For audio signal transport, copper is a tried-and-true and very cost-effective material. Starting with our Onyx line we have more than 5,000 strands of Oxygen-Free Copper (OFC) in a pair, the Sapphire speaker cables have more than 10,000 strands. Our state of the art Diamond Reference comes in at over 25,000 strands.  Thus reducing R to vanishingly low levels, only 2.3 milliohms in a 2.5 meter pair (that’s only 0.0023 ohms!). In cable construction, to reduce R, we find that more truly is better. We construct our cables with a patent-pending technique to reduce L and C to a minimum, which ensures any effect they might have is well outside the audio range. The chart below sums up the specifications for our cables, we believe these to be the best in the industry.

 Besides holding the wires together, the weaving makes for a very flexible cable that audiophiles find very easy to install, as compared with large, stiff, and cumbersome cables. Lastly, we use high-quality connectors to terminate the cables to ensure the best possible performance.

This design approach is not fancy and exciting but it works and we can prove it. We have conducted many head-to-head comparison tests against other exotic and expensive cables to prove the merit of our solution. Our cables just sound better and work well with all audio components regardless of their technologies. Our cables just get out of the way and let the rest of the system do what it is designed to do. We believe DanaCable is the best disappearing act in audio.
