@immatthewj please let us know what you’ve heard as a result of the test when you get around to it
I will do that, @audphile1 , and let us know what you wind up doing as far as your dedicated circuit(s) go.
I actually hate doing sonic comparisons, because my ears are not good at the A/B thing. It seems like I immediately hear things when they get worse, but not so much when they get better (unless something was drastically & radically wrong). When things get better, I just seem to realize over a period of time that I am enjoying the listening experience more. (There have been some exceptions to that: I can think of a few equipment upgrades that I made that were almost like a slap in the face.)
Anyway, as far as the comparisons between my gear on three circuits vs one circuit, I started thinking about another variable that I would like to rule out of the equation first. And that variable would be the effects of the brand new Romex & whether or not it burns in (or breaks in) & whether or not sonic characteristics will change if & when that happens.
With that last para typed, I am going to give my system just a couple (or so) more sessions in its present configuration before I put the four pieces of gear that I am using all on one. That will give me a bit longer to try to understand what I am or am not hearing before I switch it around; and if the new wires do, in fact, need some running time to settle in, I’d like to make sure I have got that accomplished before attempting any sonic comparisons.
