The Akiko Audio Corelli Corundum is a reference passive mains power conditioner handcrafted in the Netherlands to lower the high-frequency noise floor in audio playback chains. Operating entirely without active electrical components, inductors, or reactive power filtering, the Corelli conditions the power supply without causing dynamic compression, phase shift, or loss of natural acoustic timbre.

Housed in an aluminum chassis with an 8 mm energetically treated aluminum front panel, the Corelli features dedicated internal anodized aluminum units that separately treat phase, neutral, and ground conductors, alongside an internal ground unit enriched with corundum group minerals. A fourth internal Harmonizer unit controls high-frequency radiation fields within the chassis, while the entire assembly is potted in black resin to suppress mechanical microphonics and resonances.

KEY FEATURES & PROPRIETARY TECHNOLOGIES

• Passive Mineral-Enriched Noise Reduction: Utilizes passive internal modules enriched with corundum group minerals to lower mains noise without active electrical components or loss of dynamic headroom.
• Triple Conductor Treatment: Features separate dedicated anodized aluminum internal treatment units for phase, neutral, and earth/ground lines.
• Internal HF Harmonizer Unit: A fourth specialized internal unit targets and stabilizes the chassis' internal high-frequency electromagnetic radiation field.
• Microphonic Resin Stabilization: Internal components are completely potted in black acoustic resin to eliminate mechanical vibration and microphonic feedback.
• No-Contact Resistance Design: Omits displays, LEDs, and power switches to prevent unnecessary contact resistance, current restriction, and power line pollution.
• Premium Furutech & Silver Solder Construction: Hand-assembled using silver solder, a Furutech IEC inlet, and an Audio Grade gold-plated ceramic fuse fitted with a Tuning Chip.
