don't waste your time measuring cables it's all about the tone you like. from my experience some cables make a difference that i can hear and some don't.
to my opinion the center of your quest should be your ears not some noise meter .you are centering on specs or measurements that really mean nothing to us unless we notice it with our ears. with your system it's a crime not to use proper cables and at that level they should be treated like components(they also cost like components). before you change a component you should think about what tonal change would you like? what are you replacing and why? for example if you want a faster detailed sound or to open the soundstage and all your rca's and speaker cables are copper maybe silver cables are for you.how much warmth will you trade for speed?well..that's where the experiments should be .i advise not to spend a cent on ac solutions and power cables unless you hear a noise or problem that it will solve .there are many audiophiles that say that it has a bad effect on tone especially power conditioners.
