Beerdraft......If you have your deicated lines on different phases and let's say one phase reads 119 volts and the other phase reads 122 volts then you would have a 3 volt potential and when all connected most likely you will encounter ground loops because eveything is tied together with your IC.......When you detirmine what phase you want your dedicated circuits on make sure you check the electrical panel as not to load up one phase and maybe move some of the noisy circuits to the opposite phase. Another thing to consider is not to allow your digital gear share the same dedicated line with your analog gear. One last thing is run 10 gauge wire as opposed to 12 gauge no matter how short the runs are as it really makes a significant difference IMO...... Happy Listening
