I am getting 4 dedicated lines; two 20 amp and two 15 amp, so as to be able to separate mono amps,digital and analog components. To keep things simple, i'll be using romex 10/2 for the 20-amp lines and 12/2 for the 15-amp lines. Cryo treated Hubbell 5362 outlets will finish the lines. If i need any post outlet power treatment i'll find out later. Though benefits may be realized with these, i think the dedicated lines will take most of the way there. I'll keep you posted. Thanks for your advise!
