User reviews and community discussions praise the iFi Audio SupaNova Australian AC Plug Power Cable for its active noise cancellation, which delivers noticeable improvements in sound quality like enhanced clarity, definition, dynamics, spatial qualities, soundstage width/depth, instrumental textures, and a more relaxed, "cleaner" presentation compared to standard cables or even the passive Nova model. Reviewers note it "brings the best out of components," adds "air and life," and outperforms passive solutions across the frequency spectrum without compromising dynamics, though effects vary by system resolution and RFI levels.
Build quality is consistently highlighted as high-end and innovative, featuring air-dielectric delineators for better separation and dielectric performance, a durable yet flexible polymer sheath, 24ct gold-plated oxygen-free copper connectors, individual conductor shielding, and a lightweight pod housing Active Noise Cancellation II, Wireless Purification System, ground/polarity diagnostics (via LEDs), and surge protection.
Reliability appears strong based on limited feedback, with surge protection and ground diagnostics praised for safeguarding equipment (ANC functions even without ground prong or during ground issues), and no reports of failures; burn-in is recommended as it reduces initial "brashness".
Strengths:
- Superior noise reduction (RFI/EMI) via active tech, outperforming passive cables or add-ons like iPurifiers.
- Versatile for amps, DACs, powered speakers, subs, or desktop setups; works well with PowerStation (though direct amp use preferred over stacking ANC).
- Flexible, manageable weight, reasonable price, and Australian plug availability confirmed in queries.
Weaknesses:
- Can sound "lush" or overly voluptuous when combined with another ANC device like PowerStation + iPurifier, potentially affecting pace/rhythm.
- Requires burn-in for optimal balance; minimal direct complaints otherwise.
Overall reputation is positive among audiophiles, positioned as a "serious upgrade" and "new standard" for clean power, with enthusiasm in reviews and YouTube comparisons (e.g., "innovative design, good quality build"); community threads seek Australian stock, indicating interest but limited widespread discussion. No major negative consensus emerges from available sources.
