Corundum version – "Since its 2016 launch, the Akiko Audio Corelli power conditioner has been our best product to provide clean power to your hifi/video set without placing electronic components or active power filters in the AC path. Internally Corelli is equipped with anodized aluminum barrels whose HF-absorptive fill is specifically designed for its task. Neutral, phase and earth are each treated separately. The improved successor [€1'895] derives its still more powerful effect in part from the complex triagonal crystal lattices of the minerals of the corundum group which positively influence the operation of the new Corelli." Corundum is also known as sapphire and in synthetic form appears in watch mechanisms as 'jewels' to protect hard-wearing interfaces.
