Brand new, never used. One Acoustic Revive RAS-14 Triple-C AC Stabilizer (the current version). We opened the box for taking pictures only. All audio equipment and power units are subjected to power supply noise via power cables and ground noise through the earth / ground connection, resulting in a notable decrease of S/N ratio and a decrease in sound quality. RAS-14 removes the power supply noise and ground noise by using a special electromagnetic wave absorption material (blended natural ore) which dramatically improves sound quality and S/N ratio. RAS-14 improves the S/N ratio without any negative side effects, because the noise is absorbed and converted into thermal energy in a complete non-contact system by a special electromagnetic wave absorption material. RAS-14 also creates an anti-vibration effect by adopting in the main body a natural Hickory (High density and superior in the acoustical property) and a Carbon fiber (superior in outer noise defense and vibration control), resulting in a clear improvements of the sound stage and phase characteristic.
