Condensing a wealth of accumulated knowledge into a single, seamless piece.
PWAUDIO does not only focus on the purity of the wire material or the type of material used. We have pursued our ideal sound through thorough acoustic design, exploring minute sonic changes within major transformations by considering conductor structure, shielding, solder, and connector materials. For Ainishiki, we have condensed the knowledge gained through our high-end cable development into a simple 2-wire braid that is light and easy to handle as a portable cable. Furthermore, we have advanced the insights gained from "No.15" and the design philosophy behind ORT, incorporating a complex and precise internal conductor structure and a unique positive/negative asymmetrical design. In addition, through repeated tuning while incorporating feedback from Japan, it has been finished with a sophisticated sound that harmonizes detailed information, crystalline transparency, agile response, and a three-dimensional, expansive soundstage.
One in a million. A conductor structure that considers acoustic design from the world of microns.
The conductor design adopted for Ainishiki features ultra-fine copper strands measuring approximately 0.058mm, each individually insulated with a multi-layered enamel coating. Furthermore, seven strands are twisted together to form a single conductor bundle, which is then tightly wrapped in a spiral pattern with fiber threads to create a high-density protective layer. This shapes the conductor bundle and stabilizes it as a single structural unit. By minimizing changes in conductor positioning caused by cable movement and mitigating micro-vibrations and friction, we have pursued mechanical stability in the transmission path. This suppresses interference between the strands within the conductor as much as possible, meticulously bringing out the texture of subtle signals and the details of the sound image.
Adopts a unique asymmetrical design to achieve both delicate expression and a sense of scale.
Aiming for an expansive, transparent, and three-dimensional sound, we have combined copper wires with different conductor structures and volumes, assigning specific roles to each. It took a significant amount of time to develop, as we carefully balanced conductors of varying core diameters for the positive and negative signals to achieve our ideal sound. By researching an immense number of combinations, our positive-negative asymmetrical design allows just four cores to achieve the spatial clarity, high information density, rich expressive power, and precise response typically found in cables with many more cores.
Same conductor structure as the highly acclaimed flagship
The 26AWG positive conductor employs the same conductor structure as the PWAUDIO "Orpheus," despite using a different copper material. A high-density protective layer, fiber insulation, and multiple independently insulated fine-gauge strands—bundled with a fiber protective layer—are helically twisted to form a single conductor. This complex internal structure ensures overwhelming information density through precise signal transmission and delicate expressive power that captures even the finest signals.
Design innovations that achieve dynamics belying a compact appearance
To ensure a large cross-sectional area exceeding the equivalent of 22AWG for the negative conductor, we have arranged up to 20 internal conductor bundles at high density without forming a protective layer around each individual bundle. By balancing the structure and conductor volume against the positive side while suppressing return-side conductor resistance, and by achieving sufficient current capacity and low impedance across the entire signal transmission path, we provide superior dynamics and a wider, more three-dimensional soundstage.
Each piece is carefully and rigorously finished by hand.
A skilled craftsman, constantly exposed to vast amounts of solder from around the world, has selected the optimal solder from both bonding and acoustic perspectives. We have adopted a custom silver-copper solder, adjusting its combination with the wire structure repeatedly, to aim for a tranquility that leaves no unnecessary presence in the background of the music. We use PWAUDIO's own high-quality, laser-engraved plugs and connectors, which feature superior robustness and corrosion resistance. The ear-hook section undergoes multiple processing steps with no gaps to enhance connection stability and reduce the risk of wire breakage.

The color scheme of indigo blue and gold visually translates the sound of Ainishiki—which combines smooth luster with a sense of dynamism while vividly highlighting details from within the silence. It offers high flexibility and resistance to touch noise, achieving a balance of high quality and convenience. Furthermore, for the internal PVC, we have adopted a high-grade medical-use PVC known for its excellent high-frequency characteristics rather than standard PVC, ensuring an ideal balance between manageability and sound quality.
