Nordost Customer Testimonial

Nordost is always thrilled to receive and share glowing reviews from journalists and experts in the industry. However, when we get testimonials from our devoted and satisfied customers, it means that much more!

Thank you to Rocco from Italy for giving us a glimpse into his reference system, and sharing how Nordost has been such an integral factor in reaching “musical heaven”.

“I’ve tried many other brands of cables and audio accessories before (all top range products), but Nordost’s products perfectly match the neutrality, resolution, and tonality of my Burmester gear. The Burmester Reference Line system, set in my custom-built, concert hall-inspired, acoustic hall, delivers natural and substantial sound with a perfect tonal balance, sense of timing, and deeply impressive dynamics. It is articulate, polite, and large-scale, with refined delicacy, authority, great composure, and an alluring sense of refinement, coupled with just a hint of richness, that makes it easy to enjoy. In a few words, it is the essence of musicality. It processes with immaculate agility and subtlety to deliver low-key music with an exceptional transparency and smoothness. Even at very high volumes, the system never sounds rushed or stressed. Rather, it has a superb sense of fluidity, musical warmth, and an incredible wealth of details—the detail resolution is sky high.

In using Nordost cabling, my Reference System has reached “musical heaven” in terms of sound, and I’m very happy with the results achieved. There’s a natural side effect to this kind of insight that it makes music sound simpler (in a good way), allowing the listener to follow individual musical strands with ease. The sound stage is wide and deep, and populated by immaculately focused instruments. There’s a superb sense of sonic stability in the system that remains untroubled, even as the music explodes with adrenaline-filled dynamic shifts. The position, solidity, and intelligibility of instruments have a perfect precision in their virtual space and aren’t affected one bit. The Burmester Reference Line system manages to convey the warmth and feeling in the lead vocals with mesmerizing realism. To my ears, this kind of composure is rare to find, even at this high-end level; it clearly speaks to the heart as well as the mind, which is a rare thing. I consider the Nordost brand to be the absolute best of the best. They produce the highest quality cables with no compromise. With them in my system, I achieve reference-level sonic performance as I have never, in my humble experience, heard before. Cheers.

Rocco’s system uses ValhallaQRT, and Sort Systems.

What’s your Nordost story?

How does cable design affect the audio performance of digital cables?

When you’re looking for a digital interface, cable design is of the utmost importance, but what aspects of cable design matter, and how do they affect the performance of your digital cable? There are several electrical characteristics to consider, the top four being: characteristic impedance, capacitance, shielding and transmission speed. 

Characteristic Impedance: 

When speaking about the impedance characteristic of a digital signal, it is important to note that, while you may want to focus on the cable alone, the transmission line of a digital signal starts where the RF signal is generated inside the digital source and ends where the signal is decoded inside the digital receiver. However, for the cable alone, the impedance characteristic is defined as the ratio of voltage to current at the input to an infinite transmission line. The stability of the impedance characteristic depends on several design aspects of the cable, including conductor size and geometry, insulation material and the thickness of that insulation, and connector quality and type (75 Ω for S/PDIF, 110 Ω for AES/EBU, 90 Ω for USB, and 100 Ω for UTP Ethernet cables).


In digital cables, high capacitance of a cable will slow down voltage transitions, causing an unevenness to the flat portions of a square wave. When this happens, the D/A receiver on the other end of the signal will have a harder time identifying the data transmission. Many aspects of cable design that help to minimize capacitance are the same aspects that affect the impedance: decreasing the conductor diameter, changing the conductor geometry, and using insulation with a low dielectric constant. The art of designing a high-quality digital cable is finding the balance between what needs to be done to keep capacitance low and avoiding negative impact on the characteristic impedance of the cable. 

To keep capacitance low, Nordost implements their proprietary Mono-Filament technology in their digital cable design. By intricately and uniformly wrapping single or twisted pairs of FEP Mono-Filament around each conductor before encasing them in an extruded layer of high-quality FEP, each conductor is surrounded by its own air dielectric. In decreasing the interaction of the conductor to the insulation, the signal is no longer hampered like it is in more traditional digital cable designs.


Whereas in analog interconnects shielding is used only to keep foreign elements away from the signal, in digital transmission, shielding both keeps external radio frequencies and electromagnetic interference away as well as keeping RF signals inside of the cable itself. When designing a digital cable, one important thing to keep in mind is the compatibility of the specialized connectors with the shielding material, as that will determine how manufacturers implement the shielding into the design. 

Transmission Speeds: 

While fast transmission speeds are always sought after in cable design, for some digital cables it is absolutely essential. USB cables, for example, must perform a digital handshake (where the signal travels from source to destination and then back in 26 nanoseconds) to work. When using a conventional design, that handshake is only possible at short lengths. Nordost USB cables, on the other hand, employ Mono-Filament technology, enhancing signal speeds so much that we are able to build cables twice the length of a standard USB cable or longer, and still achieve a reliable handshake.

Dealer Spotlight: Audio Connection, Sydney

By Bjorn Bengtsson

Audio Connection was founded by Josef Riediger in 1987, born out of his passion for high-end music reproduction. When he first started, Josef had a tiny shop in a the Sydney suburb, Bankstown, and sold only a handful of products (like the legendary Gryphon, to mention one brand). After seven very successful years, he had amassed enough funds and experience to move into a much larger facility in Leichhardt, where he continued to build on his earlier success. There, Josef expanded deeper and deeper into high-end HiFi and Home Cinema. Along the way, he met some amazing people from all walks of life, and built a solid reputation throughout the industry and among customers as a real stalwart of the Australian HiFi community. 

Nordost’s journey with Audio Connection started in the early 2000’s, when then-distributor Warren Stolmack brought in some earlier Nordost products for Josef to audition. Josef was so intrigued by the results he heard with Nordost in his system that he instantly signed on as a dealer and continued to spread the word about Nordost’s performance for many years to come. 

Not long after Mr. Stolmack introduced Nordost to Audio Connection, ‘yours truly’ had the opportunity to meet with the charismatic Josef, or Joe Riediger as most people referred to him. In that meeting I remember that Joe said, in his unmistakable accent, “I don’t need to hear them again, Warren already showed me. Valhalla is the best.”  This is a statement he never would have to amend.

From then on, there have been several Nordost demonstrations made in the Leichardt facility. I have had the privilege of spending several enjoyable and memorable evenings with the ever-present customer base of engaged Australian HiFi enthusiasts. One example of such a night to remember at Audio Connection you can even read about here, thanks to Soundstage Australia’s reporting.

Sadly, Josef passed away in September 2020, one week shy of his 71st birthday. His passion for hifi is upheld by the team he left behind, comprised of Janson, Jojo, Michael, Phil, Ken, and lead by his nephew, Nigel. Between this team, there’s almost 200 years of hifi experience, most of which was spent by Josef’s side, and all sharing his passion for audio. Audio Connection has recently gone through an extensive ‘face lift’ with new, superb sounding demo rooms, filled with a full range of some of the world’s most highly regarded high-end brands, as always. Including, of course, Nordost’s entire collection, all the way up to Odin 2.
