Main specifications: Schumann resonance wave (7.83 Hz) generator input voltage 12V W140 × D170 × H50 mm 220 g
Using the natural ore tourmaline, fine natural ions of about 1/10,000 of negative ions are generated. Placing it between speakers is effective. If you place the CD directly on the top opening, press the fan switch, and apply ions to the CD, the sound quality of the CD changes. The exterior has a feeling of use such as dullness and small scratches (Takahashi Nobuyuki)
Maintenance information: 2025.12.4 operation confirmed
Accessories: instruction manual power cable
Main specifications: W145 x H200 x D145 mm 2.5 kg
A virtual earth device that creates a virtual ideal earth environment, adjusts the chassis potential, electric field generation state, etc. of audio devices, and significantly improves sound quality by stabilizing circuit operation. Sound image localization is three-dimensional and extremely clear without blurring and blurring, and the texture and tone are natural and realistic, and the sense of dynamism, energy, and dynamic range are also improved. There is a feeling of use on the exterior such as scratches and dirt (Tamai Jun)
Accessories: connection cable, RCA conversion plug, original box, instruction manual
Main specifications: 85 mm in diameter, approx. 0.4 kg, earth cable length 0.5 m
