Maybe I am not very bright but I do not see how putting an expensive 3 foot wire between a wall jack connected with likely 20 to 50 feet of 12 or 14 gauge Romex cable to a box with two low cost circuit breakers then thru many feet of aluminum cable to a transformer could be expected to do anything over almost any cable unless it is replacing too light a gauge cable with lousy connectors. If one were to put a device, like a regenerator or at least a power conditioner to control spikes and dips in the line power between the wall outlet and the expensive cable, I can see where it may be of some benefit to have a better connection from such a clean source rather than the power coming from a line transformer to your wall outlet.
Am i missing something without a power conditioner?
I need your advice on power conditioners. I know there is alot talked about with power conditioners. But let me explain my situation and what i have. First and foremost i upgraded all my stock power cords. I am using and have a Krell FPB 600 amp with a Shunyata Research Sigma HC power cord. I am using and have an Audio Research Ref 6 preamp with a Shunyata King Cobra Helix CX power cord. And have a Rega ISIS cd player with a Shunyata Sigma digital power cord. I have 1 dedicated 20 amp line with a 4 plug 20 amp wall outlet that my amp and preamp plug into. My question is with these high quality power cords do i still need a power conditioner?
