I would say my understanding of electricity as it relates to a home is pretty good. Not a journeyman electrician but I get it. BUT, when it comes to small electronics it gets way more complicated for me. There is a lot happening there. One certainty is that it is much easier to blow your stuff up by starving it for power not overloading it. Brown outs are bad!!!!\n\nThis makes sense I think? you are correct I metered the outlets and there is no voltage fluctuation. but for curiosity I want to measure the amps on that circuit while in use. Buckneked correctly pointed out many variables. I’m now wondering if my music source being streaming and not cd or album. If It could very well be a fluctuating in internet service not electricity. Could a slow down in down load affect sound? I don’t have noise I seemingly lose brilliance and volume. Not even sure if that’s possible but hey it’s me.\nIf my wife can decorate a Christmas tree and have it pull 13 amps I have to be close to pushing my 15 amp circuit controlling a tv, computer, cable box, turn table security camera system, dvd, Avr, and amp. No they are not all running at the same time but all plugged in and pulling juice. What I don’t truly understand about residential electricity is when you flirt with the limits of a breaker, how much electricity acts like it’s in brown out mode before it trips? ( I have never tripped anything, I’m just discussing theory and I understand and intend on breaking the circuit into three sources. Three circuits has to be better than heating up 14g wire to its max. I am a work in progress.\n\n\nWhy would you have your cameras on the same circuit as the AV? Keep that separate and use a UPS, to keep it going if the power goes out.
