ZAVFINO 1877PHONO GRAPHENE GOLD RUSH AU/AG GOLD OCC/PURE SILVER TONEARM CABLE REVIEW PART ONE


Anyone (or at least most) being long enough in our beloved industry would agree how everything matters, when it comes to the high-end audio system. It always about the synergy and compatibility, but without proper "ingredients" setup can too quickly just become a sum of an expensive parts rather, then fully operational, harmonic whole.

Each and every part of the high-end audio chain matters, but especially with analog front ends everything is of subtle nature and as we're dealing with miniatures and fragile signal its even more important to find the proper sonic balance and harmony.


When Will from Zavfino asked me if I'm interested in trying out the Gold Coated PC-OCC Copper & Solid Pure Silver phono cable, as usually, I've done my homework and took an in depth lurking into the cables.

Review nicely correlated with the arrival of another gem, that I was really looking forward; the Thales Simplicity II Tonearm. This combo was mounted on my Audio Union Döhmann Helix 1 turntable, that has proven to be really revelatory, when it comes to any connected analog pharphenalia.

As you can read below, there is A LOT of dedication, R & D and efforts invested into this particular cable and Zavfino cables technology in general.

I think it's more then worthy to present the Zavfino way, so let us start with the story...

HISTORY


I’ve been designing working, manufacturing and consulting on cable and parts for over 18 years working in starting in Calgary and then overseas.  I started off as an extrusion line apprentice the first few years manufacturing control cables, industrial communication and Power cables for Motorola, Ericsson, Siemens and later on leading the factory into new fields such as manufacturing cables for High End brands from the USA and Europe.


As an apprentice on the factory floor I was able participate in the manufacturing process from the time the raw copper material arrived until the final jacketing was extruded over the cable. (Sounds simple but there are around 100 different variables that must be considered for a true hi-fi cable during the manufacturing process.) My years in the factory gave me an in-depth understanding of the abilities and the limitations of every machine involved in the manufacturing of the cable which gave me a unique insight on how to make “real” high end cables using each machine to its maximum potential.  My knowledge and experience of wire stranding and advance pitch techniques, along with custom insulation extrusion helped me quickly compile some very elite OEM’s in the Hi-Fi field and because during this time other factories didn’t have engineers focused on the field of hi-fi cable and thought it wasn’t a necessary.

Roughly around 11years ago I started Zavfino 1877Phono with two partners in response to the growing demand and resurgence of everything vinyl and turntable related. Around 6 years later as the company grew I put an office in Truro, Nova Scotia, close to where I grew up as a boy. I’m now rotating between three locations with as the company grows but we are still a fairly focused company. Allowing us to give our dealers and customers that “hands on feel” connection that is lost with these other big mass-produced hifi companies.


Initially we manufactured internal Tonearm wiring harness, Tonearm DIN’s and Tonearm connectors. Each of which we up-designed from what was on the market using higher quality materials and re-engineering the connectors making improving the assemble for the advanced or novice Turntable /Tonearm technicians.

Having a background in fine wire design and the market lacking any kind of selection I designed our 5Litz7 (33AWG) tonearm wire which today is used in hundreds of tonearms worldwide as well as at least a dozen famous Tonearm/Turntable manufacturers.


When we first started the workshop in we were re-wiring vintage arms from SAEC, Micro Seiki, Audio Fidelity, as well as some Rega, which were shipped in from all over with some even coming in from Europe and a handful from Asia. Engineering on the tonearms and turntables from the early 80’s to 90’s to this day is still unmatched to some degree and if you look at todays tonearms you can easily seet their design foundations are Audiocraft, Audio Fidelity and SAEC.  Sadly introduction of the CD killed off many of these great companies before they realized vinyl was not really lost.


Many of the arms we serviced needed new internal wire harness that was lightweight, and won’t influence the vertical and horizontal movement of the tonearm bearing/arm, which we provided with our 5Litz7(33AWG) tonearm wire. At this type we also began repairing and replacing parts on these arms, such as bearings and also doing direct rewires where we had to develop all new cables at low capacitance to match the performance of the arm and the requirement used by the cartridges in present day with the increased popularity of MC carts over MM carts.

As word of mouth grew and more and more customers were using our Tonearm wires we introduced complete tonearm cables at several different levels from entry to a Pure Silver with carbon Din’s to fit many famous manufacturers arms. We also developed more Turntable related products as our dealer/ distributor network expanded such as record weights, turntable mats and headshell leads. Naturally with my background we designed a full line of High End cables (Power, Audio, Speaker Cables).

From here I designed a Tonearm cable line that was actually geared towards tonearms at various levels and not a DIY fix.   As demand grew we later added our audio cable line and of course AC power cable  all using our own engineering techniques.

Note* Our internal stranding for Tonearm, Audio, Speaker all use our H-Wound™ Litz tight pitch stranding technique which means a horizontal stranding pitch meaning more conductor “per inch” than traditional cable designs by others. It is actually twisted much like a guitar string with upwards of 16000 Twists/m

WHY 1877PHONO AS A BRAND?


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.

*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 work around 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 has developed a remarkable new technique for twisting stranded wire tightly around a central solid-core conductor. An electrical phenomenon 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. We 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 us 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 is 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, we 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.

Our new H-Wound™ stranding technology allows us to protect the delicate electrical signal being transferred through our cables. Combined with Zavfino’s 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 unequalled purity and honesty to all forms of music. The results are previously unheard details, finesse, and accuracy across the frequency spectrum.

ZAVFINO’S DEEP CRYO™ + ULTRA SONIC 7™ THERMAL BREAK-IN TREATMENT


Deep Cryo™ Treatment

All of the conductors used in our cables undergo Deep Cryo™ treatment before the insulation is extruded over the metals. Our research has proven that the conductor—and only the conductor— benefits from cryo-treatment. Materials such as poly-vinyl 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 determines the specific temperature within the -186ºC to -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, we 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 residue.

After each individual wire is processed, we strand it into bundles and then subject the bundles to further treatment. During the second stage of the ultrasonic burn-in, we increase the voltage to a higher level that’s just below the threshold of the conductor. This adjustment in temperature allows us to get a 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 our 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  exible.

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.

What is Zav no ZGRAPh-LDPTM...?


Zav no is the firstrst audiophile cable OEM to integrate graphene insulation into high-end A/C power cables as a dielectric shield. After more than two years in development with a leading American graphene polymer research company, we’re proud to unveil our new proprietary ZGRAPh-LDPTM conductive shielding/dielectric, first used within our Silver DartTM OCC A/C power cable.

The results of using ZGRAPh-LDPTM

1. Superior protection from electromagnetic interference as the graphene contour moulds to our copper shields and prevents EMI spikes. The end result is improved grounding and vastly superior
signal transmission.

2. Graphene has excellent Electrostatic Discharge (ESD) properties that eliminate static electricity and tribo-electric charging; both of which can negatively a ect a power cable’s performance.

3. Graphene’s high heat de ection reinforces the dielectric by 30%. This ensures that all of Zav no’s cables that are shielded with graphene will deliver unchanged performance for decades to come.

4. Graphene creates a 100% anti-corrosive barrier that prevents the ingress of oxygen into the shield and conductors. An air-tight seal and zero corrosion further guarantees consistency of signal transfer at a molecular level and unchanged sonic performance for a lifetime of usage.

Why Zav no’s Graphene outperforms traditional shielding:

Electromagnetic theory stipulates that a signal inside of a closed electromagnetic  eld cannot be a ected by interference from an outside source.

Traditional dielectric insulation that uses braided Copper (Cu) or Mylar shields cannot ensure a perfectly closed  eld. 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’s primary goal is to keep any and all EM interference away from the signal’s transmission path.

By utilizing our extrudable graphene polymer jacket over the shield, our new ZGRAPh-LDPTM cover solves a myriad of electrical problems which braided shielding innately causes.

Our graphene dielectric ensures 100% coverage as it moulds itself to the traditional shield and drain of the cable. In e ect, this creates a perfectly closed electromagnetic field.
