Wow, is my comment, with respect to the total lack of noise. It's dead quiet when I get near any speaker!!! This is a far cry from the B&K I had been using. And the lack of 60hz hum from the cable system is gone also. Balanced, which people love to debate, will be my choice when available. And the Harmony does bring harmony, as its name suggests. One funny thing, I'm using balanced/xlr "microphone" cables. That's what the local electronics store had, and it seems fine for the center/surrounds. 20 gauge, neutrik ends, and I am thinking fine.
