Brand new in box, never used! One Acoustic Revive RGC-24 Ground Conditioner. We opened the box for taking pictures only. For audio products it is ideal to get high quality grounding from the earth. Getting grounding done is often difficult, because of the environment where people live. Even grounding has been done, it is difficult to get good results because of low ground resistance. This could lead to countercurrent of noise and radio single on to the sound. Also, if there is an mistake in how dropping the ground from the equipment, there is a chance of ground loop and ham noise getting on to the audio signal. RGC-24 fixes chassis electrical current potential and electric field outbreak by virtual ground environment. This leads to stability in circuit moment, which improves sound. Inside the RGC-24 there is blend of natural ore, which has minus electrical current potential. Electrical current potential and electric field from the equipment travels through the attached cable and to inside of the RGC-24. By having an excellent ground environment, circuit movement of the equipment becomes stable. This leads to remarkable improvement in S/N ratio and sound quality. In detail, no blur in sound image, clarity and 3D impression and actual feelings increases. Also, sound field spreads out and feeling of noise is swept away, improvement in depth and dynamic rage improves. Which relates to feeling of throbbing pulse and intonation expression.
