ACOUSTIC REVIVE RIO-5 II Acoustic Revive Negative Ion Generator Working OK There are some scratches, but there is no major damage and the sound quality is good. Thank you very much. 【Specifications】 Retail Price: 60,500 yen Size: φ145 x H200mm Weight: 2.5kg Power Consumption: 4.0W 【Details/Features】 Generates pure natural negative ions and far-infrared rays, improving the sound and picture quality of discs and improving the acoustics of the room. When placed in a listening room and the power switch is turned ON (the electric fan switch is OFF), the light and heat of the halogen lamp generate natural negative ions, and the purification effect in the air improves the way sound waves travel, significantly improving the playback sound of audio. Place CD and DVD software on the top of the RIO-5, the DISK installation surface, and when the electric fan switch is turned ON, the electric fan will operate for about 8 seconds, creating a subtle air convection and efficiently irradiating natural negative ions onto the disc surface. The sound and picture quality improvement effect after processing both sides of the disc is truly dramatic. The sound quality significantly improves the S/N ratio and dynamic range, and the texture of each instrument and voice becomes more lifelike. In addition, the image has a deeper black and the gradation of dark colors is dramatically enhanced.
