Brand new in box, never used! One Acoustic Revive RPC-1 Audio Power Supply Conditioner. 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. It is the original 230 volts European version. Retail price is 2.795 euro, now for 1.899 euro only. The original box and manual are included. Check our other listings for more interesting items. Free shipping worldwide!
