I run three dedicated, 20 amp # 10 romex,to my system.
One line into a Hydra 2 for the digital stuff(Esoteric X03,LSA volume)
Line two into a guardian 2 for my Steelhead and SME tt.
The third line is into a Furutech GTX d and into a Furman balanced power conditioner for my tube Acoustat servo amps.
I tried running the servo amps directly from the Gtx, but the tube amps like the extra filtering that the balanced power gives them.
I did not notice any loss of power or slam by doing this.
I find it sounds even more dynamic now that it did before.
So dedicated lines are the way to begin, but not the end when it comes to fixing your power.
There are lots of other areas to investigate relating to powering up the system.
The more I've tried the" stuff that can't make any difference", the more differences(for the better) I have found them to make.
