Am I hearing things?

I just an extra  new dedicated line run beside the other one. with 10 gauge wire, 30 amp breaker and a 20 amp rated outlet. I don't think it sounds as good!!! What the hey. A little shrill in both vinyl and CD. I'm comparing from what it sounded like last night. Does electricians wire, breaker and outlet have to burn in? Am I alone in this. I'm have a whole system AC but in and the temp got up to 80. Maybe that is why. Also I'm listening at 11 am EST. So the power grid may have an affect. Did I just answer my own question or have other people experienced this. The original dedicated line was put in in 03 with 12 gauge wire, 20 amp breaker and a 15 amp outlet. Are these 2 lines picking up interferrence?

blueranger:

Why did you need to go to 30amps? Just fitted my system with a 20amp circuit for just the class A monoblocks and that's plenty of power. Are you using any kind conditioner or isolation transformer? The latter will solve those grid problems you refer to.

I put two 20a dedicated lines in the new house when we moved in last year. Took them a couple weeks to lose the shrillness and settle.

It's not especially wise - and may be against local code - to put a 30A breaker on a line with a 20A outlet. Similarly, I wouldn't put a 20A breaker on a line with a 15A outlet.
If your lines run close to each other or in the same conduit, it is possible that one is affecting the other.
