Torus RM-20, Shunyata Denali, PS Audio P10

I currently have the Torus RM-15 and Audioquest Niagara 1000. My Jeff Rowland 625 S2 amp, Corus preamp, Aeris DAC and Antipodes music server are plugged into the RM-15. My Marantz AV 7702 preamp, cable box, ATI 3-channel amp, and Oppo Blu-ray are plugged into the Niagara 1000. I have a JL Audio F112 v2 plugged directly into the wall, on the same outlet as the RM-15. My entire room is on a 20-amp circuit. I'm trying to get two dedicated 20 amp lines installed, but to date a couple electricians have said no. What is the best option in my situation? Going up to the RM-20, get the Denali(although I really want one unit), PS Audio P-10, or just hope I can get the dedicated lines installed?
