兩年前從Russ Andrews 官網購入，之後加入4隻ClarityMains模組，進一步改善地相位表現。終生保養。

About PowerPurifier:
Common and differential-mode inductorless, non-resonant, harmonic filter technology. Outstanding mains noise reduction, in excess of 80dB broadband.

About ClarityMains:
"Coherence Technology neutralises noise inherent in circuits... noise that is caused by discrepancies of time and amplitude in the ground plane. By increasing the underlying coherence of the ground plane, the technology neutralises this noise. When we neutralise this inaudible noise there are improvements in the performance qualities of the audio signals. And there is also an improvement in the listener's ability to appreciate and gain greater entertainment value out of the sound reproduction."
