Brand new, never used! One Acoustic Revive RPC-1K Audio Power Supply Conditioner, the original European 230 volts version. The RPC-1 has been jointly developed by a HWT and Acoustic Revive partnership. It is based upon the original idea of the late Mr. Shibata (who invented the infrared mouse). This ground-breaking new power supply conditioner reduces the super high frequency noise in the supply path. This results in a sound which has improved dynamics and energy with an improved signal to noise ratio. A unique circuit design with a combination of special coils makes it possible to remove only the high frequency noise from the supply path. This new “K” version contains the special “Kiyoh-seki” material with ultra-high negative ion emission. Features are a high ability to generate negative ion and a high radiant intensity of far-infrared rays. It generates minus-ion much more than Tourmaline. Retail price is 3.199 euro, now for 2.399 euro only. The original box and manual are included. Check our other listings for more interesting items. Free shipping worldwide!
