ALLNIC ZL TECHNOLOGY CABLES
"Allnic Audio's Kang Su Park is a well-respected South Korean vacuum tube designer. To his name and under his belt are many amps, preamps, DACs and phono stages. Yet today's review is about cables. "So," you think dismissively, "active cables with valves then?" Not. Mr. Park is a serious engineer, not a jester. His ZL for zero-loss cable line is simply an attempt to apply solid engineering to prevailing signal-transmission challenges. To reduce contact resistance between a conductor and its termination, he eliminates solder and hot-welds at 3'000A/1000°C [right]. This creates a molecular merger and single material at the transition point. With it he claims conductivity far superior to even the best boutique solder. To eliminate not just electrical but magnetic noise for his digital and analog interconnects, he runs mu-metal shielding*, the same nickel alloy which traditionally shields noise-critical transformers like phono stepups. To improve contact pressure, he uses special heat-treated Beryllium-copper sleeves, double-bladed spades and pins with six pressure slits. He believes those contacts improve grip over traditional bronze, pure copper or phosphor-copper variants. Finally there's his mysterious MRCT aka midrange control technology. To combat a midrange-centric perspective, Kang Su's recipe addresses the frequency extremes with a strategic combination of thick gauge (better bass), low capacitance (better treble) and specific plating for a particular impedance (midrange). These then are the core design parameters which he applies to his RCA and XLR interconnects, speaker cables and power cords. Presently the latter are available only with EU/Schuko and US plugs."

Zero Loss Technology
Zero Loss Technology includes Speaker cables, Power cables, Phono cables, and Interconnect cables. All of Interconnect cables use Mu-metal as a braided shield.
Key features of Allnic’s ZL Technology cables
• Continuity of Conductor: Hot melt welding, not soldering nor clamping.
• Permanent Contact Pressure: Carved out heat-treated Beryllium copper terminals.
• Perfect shield against magneto electric noise: Only Mu-metal shield could protect, copper could not.
• Maintenance-free double blade patented terminal: No need to go backside of loudspeakers every month for retightening binding posts.
1. No barriers on conductor
With traditional soldering or clamping connection between terminal and conductor, you have two resistant barriers(solder has much bigger resistance than copper or silver). Our direct hot melt welding without solder connection removes two obstacles on the signal path, by melting terminal and conductor into one material.
2. Permanent Contact Pressure of heat-treated Beryllium copper terminals
Contact resistance is a very important factor in signal transmission. Higher contact pressure and larger contact surface mean less contact resistance and better signal transfer. With traditional bronze, pure copper or phosphorous copper terminals you could not have enough contact pressure nor permanent one. With our carved out, slit, heat-treated Beryllium copper terminals, you have strong and permanent contact pressure for minimum contact loss.
3. No more loosened binding posts
With our patented double blade terminals, you do not need to go backside of your loudspeakers every month to retighten your binding posts. Our double blade terminals not only hold tight against severe vibration of speakers but also minimize contact resistance, so please do not go backside for years.
4. Mid-Range Control Technology – MRCT®
Allnic considers that protruded midrange is the most formidable obstacle for harmonious signal transfer. Allnic’s MRCT uses metal platings for slight midrange braking and thick wire gauze for encouraging low frequencies and controls capacitance forever evasive high frequencies.
5. Free from every disturbing magnetic noise
With traditional copper or silver meshed shield, you have not enough protection from magnetic noise. Copper or silver could protect well against electric noise, but very poorly does against magnetic one, because magnetic signal freely penetrates copper or silver. Only Mu-metal(Nickel alloy material) could protect your audio signal from both electromagnetic noise. Data shows Mu-metal reduces magnetic noise to 1/32 times( – 32dB), of course it protects electric noise perfectly either.
