Dedicated Line - Things to consider

That’s exactly what I’m hoping for - lower noise floor. And that is a huge improvement if that’s what the outcome will be.

Yes, universal agreement on the benefit of direct lines. Sure, beyond that, I am sure there is additional benefit to audiophile  grade wire, specifics of the hookups, increasing grounding… it goes on forever. I just tend to go one increment at a time. Basic direct lines is a must as a start.

@audphile1 , okay, so this is where some of the disagreement comes up, and I am not saying that I am in either camp (yet) as I just don’t have enough experience (yet) with doing the comparisons. To trim it down to a nutshell: there is the point of view that more than one dedicated circuit for the audio gear introduces RF because all have the neutral/ground bar in common. Electricity is not a strong subject for me, but if you are interested in more on that POV, in one of those links I pasted up above for you, MillerCarbon explains his thoughts on that particular area of the subject. Then there is the POV that if the lines are correctly segregated and if everything is done optimally at the service panel, RF won’t be a problem. In another link I pasted up above (this one was a question/topic that I started) Jea48 states that to be his POV and explains how to achieve that.

Again, I don’t know yet. But sort of where I was going with all of that is that when someone says that they have two or more circuits & no issues with RF, I think that it could be possible that they may have stuff going on that they don’t or won’t know about until they hear it without that stuff. But again, I honestly don’t know.

Going back up to your original question, installing two or more circuits would give you the option to experiment. And if it turns out that you wind up in the MC camp, you really are not out that much. You can trip the breaker(s) that you decide not to use and then you will have additional circuit or circuits available for something else or that you can move somewhere else to do something else by using junction/work boxes and buying some additional Romex. My own circuits started out terminating in one location, I later branched them to another location, and then later I put them in still another location. Most recently, I decided that all the moving around I did with them to get to where they are now was done less than ideally (from an ’audiophile perspective’) so I added three more circuits for ONLY the listening room  I am in now, and those 3 circuits are now direct from outlets to service panel. Meaning I now have 3 more circuits in two more locations (with 6 duplexes) in the rest of my house.

And I have been putting this test off long enough, so tonight after I turned my system (on 3 circuits) off I started looking around through my odds & ends, and I actually have what I need to get all my stuff on just one of my dedicated circuits. The stuff I will be using isn’t what I would consider ideal from an audiophile quality perspective, but maybe it will give me some clue as to how I feel about the subject, and lets say that I do hear improvement when I have my stuff all on one, then I can spend more & upgrade the stuff I am going to use to acheive the all on one circuit system.

I am dedicated to dedicated.

@immatthewj please let us know what you’ve heard as a result of the test when you get around to it
