Dedicated circuits
I just completed installing 2 dedicated circuits. After reading several threads here, I went with 30 amp breakers with 10 AWG wire with high end receptacles. One circuit for the amp and the other for everything else. I’m blown away by the difference. Tighter bass, not as bright, better imaging and soundstage. Should have done this long ago.
I agree with your statement, and my explanation of it probably wasn’t as specific as it could have been, but I didn’t want to get too crazy with theories, formulas and examples. Anyone is free to supply some if they wish.

That is true. For AC induction type motors if voltage goes down due to Line voltage drop, current go up. Not so for audio equipment power transformers. If voltage drops so can/does current as well as wattage, (VA)... In the case of a power amplifier lower wattage, lower power... . |
Another question sort of related to the dedicated circuit topic: either here or on AA I once read something to the effect that the class D of most powered subs would "dirty up" the power for whatever other audio component was on the same circuit. I apologize if I am misquoting this, this is a rather foggy subject for me. So my questions are: is there any truth to that, and if so, I guess that means your sub should be out there on it's own island? I am currently running my amp on one circuit, my pre and my CD player on another circuit, and due to what I typed above being stuck in a cloudy recess of my brain, I have my sub on it's own circuit. . . . |
@peter_s Synergistic Research’s latest “Purple” (it is actually black) duplex receptacle is an isolated ground type. All this focus on dedicated lines, wire gauge and breaker size makes me think it would be beneficial to remind everyone about the importance of having a good grounding system. We just moved into a 17 year old house a few months ago and I could not locate the existing outdoor grounding setup to the main panel which concerned me. This week I had an electrician install new ground rods and large gauge copper conductor connecting them to the main panel ($375). It was done per NEC and local code. I was not expecting any effect on the sound quality of my system, but I was shocked at the improvement in lowering the noise floor and the elimination of a slight-but-annoying glare on female vocal peaks that I have been wrestling with. Another unexpected bonus was that my wife commented that night about how much better the picture was on our plasma TV. Definitely great bang-for-the bucks! I then starting researching grounding systems and found out that the life expectancy for a copper-over-steel-bar grounding system is only 5-10 years!
