Based in Cedar Knolls, New Jersey, it is run by Howard Sosna and Joe Kubala who both have a single-minded dedication to developing the highest performance audio cables in the world.

Howard Sosna became interested in stereo equipment at an early age, building speakers and Heathkit electronic components for himself along the way. Joe Kubala has also been involved with audio equipment since college. After graduating with an engineering degree, Joe became more involved with the technical aspects of audio. Along the way they both became convinced of the pivotal role cables play in audio performance.

Having made the decision to put their innovative ideas into production, Joe and Howard began a long process of building cable after cable, using different materials, wire gauges and number of conductors in different combinations and geometries. Each interconnect, speaker cable or power cord was carefully listened to in both systems – one all solid state, the other all tubes. Some changes moved performance in the right direction, others did not.

The result is the OptimiZ Architecture which underpins their cables: cables which are among the best performing in the world today.


Kubala-Sosna Realization!

Kubala-Sosna's new flagship, this cable utilizes an extreme level of OptimiZ3 architecture, raising total performance to unprecedented levels. Realization! has the largest performance envelope they have ever produced, and we encourage you to audition this cable against any in the world.

Impressive on all fronts. Most of all, it allows you to pay attention to the music with no distractions. Kubala-Sosna’s best—and quite probably—the best.

"There is no question in my mind that the Kubala-Sosna Realization USB cable is the finest USB cable I have yet auditioned."

Kubala-Sosna Elation!

A reference cable that provides staggering, unprecedented levels of performance. Elation! has the ability to transport you to the venue, allowing you to connect to the performance like no other cable in the world.

Compared to Emotion (which is arguably one of the best cables in the world), K-S’s new Elation! offering introduces OptimiZ2 architecture that raises total performance to new, heretofore unheard-of levels.

“I am now prepared to elevate the new and quite phenomenal Kubala-Sosna Elation Interconnects, Speaker Cables, and AC Cords to State of the Art... My congratulations to Kubala-Sosna and their design team for elevating my listening experience to new celestial heights of realism with the Elation. Recommended reproduction of their music where cost is no object.”

Kubala-Sosna Emotion

Emotion is truly a collection of master reference component links. We have been told many times that audiophiles "did not really hear their systems" until they connected to the performance with cables from the Emotion ensemble!

The capabilities of these component links are hard to describe because the words have all been used over and over again. Everyone claims "perfect" performance, yet, most cables sound very similar in most regards, somewhat different in one or two aspects.

“The Kubala-Sosna Emotion interconnects connected me to the music like no other interconnects I've heard, at anywhere near the price.
It's hard to believe I am just talking about interconnects, but the Emotions are system-transforming, and they involved me in the music like never before.”

Kubala-Sosna Expression

Expression cables utilize a different version of the OptimiZ architecture found in K-S’s Emotion series component links. The Expression Series is the equal of many well-respected top-of-the-line cables, possibly bested only by K-S’s own Emotion and Elation ensemble.

During a certain phase of K-S’s development and testing, they knew they had something that challenged the state-of-the-art. Something that would compete with almost anything made. 

In a blind test, three different developmental versions of this series were chosen over some of the most expensive and respected cables available; and the final version we brought to market performs better than any of those three!

“The Expressions are at component level prices, at least for my system. I know some will squawk, as is their right, but a complete set of Expressions provided for me a component level upgrade.
While I really dislike that power cords, interconnects, and speaker cables are so expensive, in this case they made a large difference. I surrender my prejudice and line of reasoning. If it takes expensive cables to get the sound my system makes with the Expressions, then that's the price of glory. Highly recommended.”

Kubala-Sosna Fascination

Fascination cables represent the entry into K-S’s RevolutionZ series, a truly high-performance collection of cables that begin to showcase the benefits of OptimiZ architecture.

In the development process, these cables actually came after the discovery of the top two series, Emotion and Expression. K-S set the challenge of finding a way to offer a more cost effective product using the new geometry.

The result is a natural progression of performance from traditional designs, with a definite family sound signature of the other RevolutionZ products.

“So – how to truly judge the Fascination line? Based on my auditions, these cables are so good that you really need to give them a try, preferably in a complete system approach.”
Inner Ear Review

Kubala-Sosna Anticipation

Anticipation cables are game-changing mid-range audio cables, offering performance vastly above expectations for their sector of the marketplace. 

The name was chosen to highlight the fact that there is a hint of what is to come from K-S’s RevolutionZ products in what you will hear from Anticipation cables.

Using traditional manufacturing techniques combined with fine materials, Anticipation offers stunning performance at their price point. They have to be heard to be believed.

“The K-S cables are among the quietest I've used, almost rivaling the relatively cumbersome JPS SuperConductors in that regard, and they sound transparent, a feature they share with few other competitors. Over all, they seem to get out of the way of everything else and let the system do its thing. For me, that's about the highest recommendation I can make.”

Kubala-Sosna Imagination

Imagination Cables offer astonishing levels of performance at their price point. They are appropriate for stereo or high-end home theatre applications.

These component links will help you recreate a live concert to raise goose-bumps on your neck, or lose yourself in the immersive fantasy that has always been the ultimate aim of the film industry.

Do not underestimate their capabilities: in our experience they regularly outperform cables five times their price.
