Ultra Series

The Waiheke S-Ultra blends innovation and artistry, featuring a unique Silver-Copper alloy conductor composed of Monocrystalline Copper, Silver-Plated, and Non-Plated High Purity Copper. Each conductor is cryogenically treated and insulated with Cross-Linked Polyethylene (XLPE), while Polytetrafluoroethylene (PTFE), air-tubes, and natural cotton optimize vibration control and signal purity.

Its sonic clarity is further enhanced by proprietary nano Quell Technology (nQT)—a multi-layered composite infused with nano coatings, positioned beneath a solid Natural Walnut Wood ring for superior noise dissipation. Hand-polished stainless-steel and walnut accents elevate durability and visual refinement, reflecting a commitment to engineering excellence and pure sound reproduction.

Based on a sophisticated triple-bundle balanced design, the Whanganui A-Ultra adopts a unique blend of Silver-Copper alloy paired with premium Monocrystalline Copper and Silver-Plated High Purity Copper. Every conductor is cryogenically treated in-house within an advanced facility and insulated with high-quality Cross-Linked Polyethylene XLPE dielectric. This careful formulation delivers a pristine, detailed and smooth, yet dynamic and powerful sound delivery.

To safeguard the pristine signals from interference, an elaborate tripled-shielded design is deployed to provide very high levels of shielding against both internal and external interference, such as RFI/EMI. Each of the bundles contains layers of end-to-end copper foil shielding to minimize crosstalk and is enveloped with a protective layer of premium Polytetrafluoroethylene PTFE, with all three bundles then fully enveloped by an additional layer of copper foil shielding followed by ultra-high coverage Silver-Plated braiding.​

Crafted with meticulous attention, the Wairakei P-Ultra is a symphony of innovation, showcasing a unique blend of Silver-Copper alloy conductor - a synthesis of pristine Monocrystalline Copper, Silver-Plated and Non-Plated High Purity Copper. Each conductor is cryogenically treated at the in-house cutting-edge facility and encased in select Cross-Linked Polyethylene XLPE dielectric, which is further fortified by premium Polytetrafluoroethylene PTFE insulation.

To shield the cable from potential noise interference, an elaborate double-shielding structure is employed, where the cable is fully enveloped in a layer of copper foil shielding, followed by an ultra-high coverage Silver-Plated braiding. This effectively guards against both internal and external interference, such as RFI/EMI, resulting in an audio output that is both pristine and dynamic. The Wairakei P-Ultra ensures minimal disturbance of the sonic landscape, allowing systems to deliver every note with unmatched clarity.
