    For some time now I’ve been using six harmonizers in my room with great success. Four of them are signature versions,but two were the older ones that used the optional wall wart power supply. I decided to give them a face lift so i installed the signature upgrade modules. I can definitely hear the improved qualities. A more coherent harmonic presentation,cleaner transients and the holographic qualities I love significantly enhanced. A highly recommended purchase if you have older harmonizers.
