Code 51’s powerful synergies are further drawn out with the application of Effect Audio’s custom-engineered cable geometry, the “Multi-sized and Multi-Bundle Stranded” design. Using the principle of the Golden Ratio Dispersion, to optimise precise implementation of the ratios, and geometrical arrangements of the materials to achieve a sound that can boast of being musically perfect!

  • 24 AWG
  • Selected Premium UP-OCC Material
  • Gold Plated Silver / Silver Gold Alloy / Palladium Plated Silver Hybrid
  • Golden Ratio Dispersion Multi-sized and Multi-Bundle Stranded
  • Individually Enamelled Strands
  • Superior PSquared / P-EA Plug with Titanium Casing
  • Exquisite Titanium Y-splitter
  • EA UltraFlexi Insulation
  • Cable Connector: MMCX, 2-Pin
  • Cable Termination: 2.5, 3.5, 4.4 mm


Effect Audio once again has moved beyond industry norms and conventional ideologies to present a unique expression of cable-making craftsmanship. Code 51 excels not only in its vast and holographic soundstage, superb separation and detail-retrieval capability, its deep, immersive lows and smooth, rich highs and mids all work synergistically together to deliver a dynamic, true-to-life reproduction of sound.

The Titanium-crafted Y-split, adds in a futuristic image of the new flagship cable. In terms of aesthetics, the sculptured design features an asymmetrical appearance with bevelled lateral parts, that shimmers with an ever-changing array of reflections when exposed to light. The cunning design not only enchants as a work of art but also forms the perfect complement to Code 51’s superlative sound properties.

Improve the 10%

You can definitely feel the speed improve on the lows, it improve the attack speed and makes it more precise, the high is much more clear for me with no much sibilance, definitely more holographic sound, and the looks looks durable.

So far Ok, still under test!

Nice looking, I tested with Audeze LCDi4 and 64 Audio Tia Fourté, with A&K SP 2000, it behaves better with the LCDi4: I am still waiting the 64 Audio A18s for which I purchased this cable...
