The rebel alliance.

Some things are born to rebel – like our IC-77 & IC-777 interconnection cables, for example.

Generic cables add hiss, noise and distortion to your audio, the ICs buck that trend.

Character building.

The IC-77 & 777 cables don’t add their own character to your tunes, but bring out the full character of the music itself. They remove the hiss and distortion you’ll find in other electrical cables.

From a sonic point of view, they convey the full sonic spectrum of the music from the most silent passages through to the loudest kettle drum.

Which means your music flows in crystal clear high definition.

The tech spec.

There’s a lot packed into the IC-77 & 777s, including:

  • Zero screen technology – to reject external interference
  • Solid-core silver-plated copper conductors – to eliminate distortion
  • FEP insulation – to remove dielectric absorption

It’s clear to see how music never sounded better.

Rebel with a cause.

For too long, audio has been plagued by hiss and distortion. The IC-77 & 777s remove this irritating pest and allow you to listen once again in clarity you never thought possible.

What is special about the AMR OptiLink® range of cables?

The AMR interconnection cables are hand-crafted and have three unique elements:

OptiScreen® technology which is AMR’s proprietary inductance cancelling construction. OptiScreen® provides dynamic elimination of radio frequency interference/noise (RFI), thereby cancelling any interference with nearby interconnect cables/equipment. Furthermore, the unique geometric construction combining AMR’s Oxygen Free High conductivity Copper (OFHC) cable with OptiScreen® further allows AMR’s cables to reject common mode high-frequency noise with nil current limiting effects.

At the heart of the AMR Interconnection Cable is Oxygen Free High conductivity Copper (OFHC) which is classed as C10100 under the ASTM system. This certifies that the copper is 99.99% pure with only a 0.0005 percent oxygen content. This is the highest quality of copper available and should come as no surprise that it is also the most expensive. In terms of sonic difference, our listening tests concluded that OFHC is significantly more natural and transparent than Oxygen Free Copper (OFC) which is turn, is much better than the most commonly used Electro Tough Pitch Copper (ETPC).

Hand-selected connectors and materials. The RCA and XLR connectors were selected only after extensive auditioning. It should come as no surprise that the professional Neutrik brand of connectors came top and was selected.

At AMR the overriding objective is the design and manufacture of interconnection (and power) cables that allow the music to through from the deftness to the slam; it should neither add nor detract. This is a somewhat different design philosophy to other aftermarket cables that impart a sonic footprint/restriction on the system.

We ask that you take the listening test and let us know your sonic findings to see if our range of cables are deserving of the AMR label.

IC-77 OptiLink® Reference Interconnect Cable

The IC-77 OptiLink® Reference Interconnect Cable offers transparency, detail, articulate bass, dynamic contrasts, and freedom from grain in an unparalleled fashion.

Features:

  • Minimum capacitance designs
  • Zero screen technology using unique geometric configuration to reject external interference
  • Solid-core silver plated oxygen free high conductivity copper (OFHC ) conductors
  • High purity extruded Fluorinated Ethylene Propylene (FEP) insulation eliminates dielectric absorption

AMR’s IC-77 is the same high purity extruded Fluorinated Ethylene Propylene (FEP) insulated, solid-core silver-plated oxygen-free high conductivity copper cable used internally in all AMR’s reference class components.

The IC-77 interconnect cables are minimum capacitance designs. Not only does AMR avoid adding extra filtering, AMR also omits the sonically damaging screen commonly used. Instead, the unique geometric configuration is as efficient at rejecting external interference as any screened cable.

Further, the use of solid-core only conductors avoids distortion from the various crystal boundaries forming between strands.

The use of FEP insulation eliminates dielectric absorption and ensures signal propagation at 95% of the speed of light (an illustration of the losses in cables is the difference between the speed of light and actual propagation velocity), where most common interconnect cables manage 40% to 75% of the speed of light.
