ZAVFINO 1877PHONO OCC Silver Dart Graphene interconnect review


There is something distinctively different and highly engaging about the ZAVFINO 1877PHONO cables. I’ve already evaluated and delved into the auditory impact of the ZAVFINO 1877PHONO Graphene Gold Rush Au/Ag Gold Occ/Pure Silver Tonearm cable here and they’ve earned Mono and Stereo Highly-Recommended-Product Award for many of the reasons. 

ZAVFINO 1877PHONO OCC Silver Dart Graphene interconnects are intimately analogous to the tonearm phono cable design, but contains two layers of Graphene, one which is melded to the shield like ZAVFINO 1877PHONO’ power cable. In this cable, the braid of the audio cable, and the other the outer absorption layer (larger diameter part of the cable) absorbs interferences and dissipates it as heat and requires no drain, braid or metallic shield. 


As with my previous review the ZAVFINO 1877PHONO OCC Silver Dart Graphene interconnects merits a bit more in depth technical descriptions, as a lot of them are hidden to the eye and mind.But, as you can read later on, they‘re not to the ear!

1877PHONO?


One of the first things people might ask is why the 1877PHONO name!? The story goes... The late 1800’s was a time of great innovation in North America with many great inventors such as Thomas Edison, Alexander Graham Bell and Nikola Tesla. 1877-1925 was known as the “Acoustic Era” with many breakthroughs in recorded sound and sound reproduction that lead to hi-fi as we know it today.

The year 1877 was the year that Edison trademarked the patent for his invention the phonograph. Edison was the driving force behind the phonograph/Turntable into the everyday household and in our minds the man behind what we know as Hi-Fi today.


"To us it seemed the perfect name/brand for our products as a tribute to everything vinyl and a tribute to the Edison the man and as our company’s core philosophy to develop and innovate. (I have to thank Simon for the name he came up with it when we were all brainstorming on what to call the company)". We later added Zavfino 1877Phono to our trademark to make it distinctive and easier to search for as it not only pointed to a date but directly to our company"- Will Trem.




*Also because the China trademark office pretty much said that we couldn’t trademark 1877phono as a Canadian company in China but a local could so the workaround was to make it into two separate words.  

ZAVFINO’S H-WOUND™ + ZERO STRAND LOSS


Drawing on more than 18 years of manufacturing experience, Zavfino team has developed a remarkable new technique for twisting stranded wire tightly around a central solid-core conductor. An electrical phenomenon is commonly known as the “skin effect” occurs when electrons move through any solid core conductor.

Higher frequencies travel along the outside (the skin) of the conductor faster than midrange and lower echelon frequencies. This results in smeared PRaT, muddled instrumental timbres, and an unnatural sound. Zavfino’s new H-Wound™ manufacturing technique negates the skin effect.

Originally developed by OEMs Siemens and Klangfilm, Zavfino uses a customized transformer wire-stranding machine. They've further modified the gears in this machinery to create windings at a slower RPM ratio with a much tighter pitch. This patented manufacturing process enables them to twist the wiring at the tightest pitch possible without overlapping the wire strands.

Most wire-stranding machines can only fabricate windings up to a maximum of 300 twists per meter. Setting the bar far higher, Zavfino’s patented H-Wound™ cable winding machine creates a pitch rate of 14,000 to 16,000 twists per meter; which seems to be unmatched by any other audiophile cable maker.

Zavfino’s new Zero Strand Loss™ manufacturing technique protects the bundled conductors from being damaged during stripping and termination. By ensuring that each core has zero chipped, cut, or mangled strands, they can guarantee that each insulated core is 100% identical.

"For audiophiles, the sonic results of tighter windings and Zero Strand Loss™ conductors are cables with quieter backgrounds, remarkable timbral accuracy, lifelike PRaT, jaw-dropping mid-range resolution, and superior low-frequency extension".

ZAVFINO 1877PHONO's new H-Wound™ stranding technology allows them to protect the delicate electrical signal being transferred through their cables. "Combined with our state of the art manufacturing techniques, our precision matched Pure Silver (Ag) and Gold (Au) PCOCC conductors used in the GoldRush™Tonearm cable bring an unequaled purity and honesty to all forms of music. The results are previously unheard details, finesse, and accuracy across the frequency spectrum."

DEEP CRYO™ + ULTRASONIC 7™ THERMAL BREAK-IN TREATMENT


Deep Cryo™ Treatment

All of the conductors used in ZAVFINO 1877PHONO's cables undergo Deep Cryo™ treatment before the insulation is extruded over the metals. Brand's research has proven that the conductor—and only the conductor— benefits from cryo-treatment. Materials such as polyvinyl chloride (PVC™), Teflon™, PE, and Silicon™ can all be adversely affected by cold-temperature annealing. Cryo-treating non-conductors and insulating materials can cause them to break down and become brittle.

The purity, size, and molecular structure of each conductor determine the specific temperature within the -186ºC to - a 196ºC range that we cryo-treat it at. Zavfino’s research into cold temperature physics has proven that the absolute lowest temperature is not necessarily the best for cryo-treatment.

UltraSonic 7 High Voltage / Thermal Break-in


This is a two-stage process. In the first stage ZAVFINO 1877PHONO draw the bare conductor through a ceramic die into an ultrasonic cleaning chamber that bombards the conductor with multiple ultrasonic frequencies. This emulsification process removes all debris from the surface of the wire down to the molecular level and leaves absolutely zero residues.

After each individual wire is processed, they strand it into bundles and then subject the bundles to further treatment. During the second stage of the ultrasonic burn-in the voltage is increased to a higher level that’s just below the threshold of the conductor. This adjustment in temperature allows a formation of the unique “break-in effect” normally associated with cables that have had 30 to 40 hours of signal and/or current run through them.

The results…? Most cables using OCC conductors take months to properly break-in. Zavfino’s patented Deep Cryo™ and Ultra Sonic 7™ thermal break-in treatments pre-burn all of company's OCC cables so that the end user will hear the cable at an optimal level within days instead of months. In other words, Audiophiles get better sound in a fraction of the wait time.

Zav no’s Graphene Dielectric Shielding


What is Graphene?

Graphene is an allotrope of carbon which, at the molecular level, forms a two-dimensional hexagonal lattice in which one atom forms each vertex. It is the basic structural element of various other allotropes, including graphite and charcoal. Raw graphene is a cutting-edge polymer which is both conductive and flexible.

It has many unique electrical, mechanical, and chemical properties. This makes it an ideal material for use in audiophile engineering applications.

With an intrinsic tensile strength of 130 GPa and a Young’s Modulus sti ness of 1 TPa (aprx. 150,000,000 PSi), graphene is the strongest material ever tested. Its tensile strength is about 200 times greater than that of the strongest known steels. It is also the best conductor of electricity yet known. Studies have proven electron mobility through graphene at values exceeding 15,000 cm2·V-1·s-1.

The Silver Dart Audio Interconnect construction uses 2 layers of Graphene extrusion with the outermost layer for absorption/dissipation like that used in the Dart Speaker cable and the inner layer of Graphene extruded over the mylar/drain/braided shield making a perfectly enclosed field.

Traditional dielectric insulation that uses braided Copper (Cu) or Mylar shields cannot ensure a perfectly closed field. Copper braids and Mylar wraps both have gaps between their overlaid bundles and layers which inherently occur during manufacturing. Low frequency interference and high frequency noise will slip through these gaps and cause electromagnetic contamination and sonic degradation.

ZAVFINO 1877PHONO's Graphene insulation moulds itself to the shield layer creating a perfectly enclosed field and further insulates on the outer layer by absorbing electromagnetic noise.

One of the properties of ZGRAPh-LDPTM Graphene material absorbs electromagnetic noise and transfers it into heat. As this energy transfer occurs, zero inductive current is produced. In the aggregate, the total inductive current within the cable shield is minimized and the noise level is drastically reduced.

THE MUSIC


When it comes to this part of the review, it’s all about the challenges... The little, grande and the particular ones :). 

Let me for a change start with the drum reference challenge. I’ve been often asked to suggest a truly challenging drum album and Zlatko Kaučič’s Music For Drums and Percussions will not disenchant. This particular recording will not merely call for the real world cables’ performance and challenge a correct system behavior, but will also challenge your perception of the music. Iconic Slovenian drummer solo album introduces an artful collage of drums, toy’s, kitchen utensils and different homemade instruments. 

If you’ll source the album, be careful with the volume as some parts of the recording are really hitting hard and are instantaneously “dangerous”. This is an avant-garde drum poetry, that might be a bit too much of intake for the occasional audience, but do mind that Zlatko is a musician of a higher pedigree and he has collaborated over the years with many musicians like Paul McCandless, American multi-instrumentalist and founding member of the American jazz group Oregon. This album carries a unique and refreshing vitality. There are few moments, that will call for the reality check as some of the instruments (especially metallic percussion) are recorded with a life-like believability. 

The ZAVFINO 1877PHONO OCC Silver Dart Graphene interconnects capability of the transportation of the unprocessed signal’s vitality was something I’ve repeatedly put into the ink. In the combo with Lamm Reference L2.1 Reference Hybrid preamplifier and ultra-transparent MSB Technology Select DAC, as well as with utterly dynamic Aries Cerat Kassandra 2 Sig DAC the OCC Silver Dart Graphene interconnects surprisingly acted way above the predicted threshold. There are actually not a lot of cables on the market that can deal with the objective transmission, transparency, and dynamics conveying, yet OCC Silver Dart Graphene signal cables performed their duties beyond just an assignment done adequately.

The other record well worth pointing out is coming from our Senior Contributing Writer Stefano Bertoncello. It’s another analog gem worthy of pursuing to allocate! The Barocco Tedesco was tapped on the Revox G 36 tube tape-recorded custom modified by Tim De Paravicini. Two Neumann U67 tube-mikes were used as well hand picked ‘60 N.O.S. Telefunken Flat-Plate tubes. 

So what can one expect and what is the specific quest taking the place? Something, that as de facto explores micro-cosmos of the tiniest portions of the sound that is requisite in re-formulation of the acoustical space as well as the atmosphere. It’s all about the compound density of this quark like fractions of time. Some of them can be visualized via multiple particular software programs (FFT etc.) and occasionally I do lurk into the diagnostic side of the affairs. Still, the primary element will invariably be a listening part. Yes, I’m a techie by default. Then again, I’ll be always of the music’s first gnome origin. I’ve grown up into the music by the music and this is simply a part of my unchangeable DNA. Period!

The ZAVFINO 1877PHONO OCC Silver Dart Graphene interconnects competitive ability to project time or space they act exemplary, without considering price mark, brand origin, and known technical declarations. Silver Dart Graphene cables’ expression of time-related portrayal in the frequency domain was again above forecasted and with the stimulating candor and easiness of music’s vitality teleportation!

Probing the non-ending universe of decays, delays, minuscule fractions and formations snippets the harmonics and notes overlays are the leitmotif of the Ustad Zia Mohiuddin Dagar ‎– Raga Mangeyabushan (Disques Alvarès ‎– LD 114) vinyl record. This out of the box album was released in France, way back in 1974 and it’s still among my favorite records I’ll leave the Raga further studies to the everyone interested, but it’s the harmonic framework revival ability where did the ZAVFINO 1877PHONO OCC Silver Dart Graphene interconnects had particularly exceled.  

There is no comprehensive high-end audio cable and there will never be one. Many important factors are beyond the plain impedance matching. For anybody in apprehension, do your homework. There are volumes of information to examine... Simply investigate military and alternative industries endeavours and mind-boggling founds supplied into the evolution and expansion of the interlinked cables…

CONCLUSION


Trying to explain the impact of the ZAVFINO 1877PHONO OCC Silver Dart Graphene interconnects is a bit (positively) complex as its the name itself. 

There are so many interesting technologies implemented with Silver Dart Graphene interconnects and these cables are maintaining the price/performance stand out value previously set by the ZAVFINO 1877PHONO Graphene Gold Rush Au/Ag Gold Occ/Pure Silver Tonearm cable. 

As I’ve reported in my tonearm cable review, there are no hidden agendas with the ZAVFINO 1877PHONO cables. The brand openly and proudly shares their technological advantages and unique processes of the manufacturing. This healthy stance is quite contrary to many of sky-high priced boutique audiophile cables. I can understand the IP protecting part, but as a reviewer, I’m always more enthused and animated, when I have something more to examine and write about. 

At the end of my listening notes, I’ve challenged my self with a question. What makes these cables so special and so different. Sometimes the abundance of technical pieces of information can lead to less than a perfect transition to the pen. As with my first Zavfino 1877PHONO cable review, I didn’t have any problems conveying the music’s sphere into the words. If you’ve made it so far in this evaluation, the Music section above already explained quite some of the ZAVFINO 1877PHONO OCC Silver Dart Graphene interconnects’ advantages and stand out attributes. Diversity is a key word!

The wit sonic rush naming still stands as well as ZAVFINO 1877PHONO OCC Silver Dart Graphene interconnects’ capability to blend technology, science, and art into such a compelling performer. It’s never easy to affix all of the effective attributes, but one of the forte features of the Silver Darts’ is certainly the above-mentioned capacity to fuse so many different technological processes into a such sonically empowered cable, that for a healthy change lets the raw music‘ energy floating through the cable veins rather than functioning as an equalizer and a sonic brake!

I didn’t have to think twice in honoring ZAVFINO 1877PHONO’s achievements and standouts with Mono and Stereo Highly Recommended Product Award. The same extends the for the OCC Silver Dart Graphene interconnects! There are many reasons why these cables are establishing not so silent stirring in the market. In the era where many audiophiles and music lovers are highly priced consciously, Will, Simon, and their team are accelerating their pace and pushing the limits of price point limitations a few bars up on the ladder. 

It’s always encouraging to encounter, evaluate and nonetheless most importantly to listen to such price conscious high-end audio creations.
