I've just gone down the path of upgrading my power cables in my system (added a pangea ac9 for my parasound hca 1500 amp, and a pangea ac14 for my oppo dv981 which I'm using as the preamp). Definitely am a believer in the improvement from the cords. I just picked up a signal cable magic power cord.
At the moment, I have two possible places to try the cord. From my wall outlet to the rotel power conditioner (to which the parasound is hooked up) or to my subwoofer to replace a decent 14awg power cord that I replaced the stock with). Any suggestions on which would be a better place. My gut says the rotel. Just wanted to hear some feedback. Thanks.
