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?

No its the sound room labeled. I have 2 dedicated lines with 2 outlets 3 inches apart. I hooked up the Bryston to the new line with the 10 ga wire and my power plant to the other one. sonically everything is great now but I will change it out to a 20 amp breaker. Thanks for everyones input. Memebers here look out for each other.

In the 60's they did the common neutral to save copper, some houses back then were wired with aluminum. Code now is the breakers have to be ganged on common neutrals  hot needs to be on seperate phases. the reasoning is both of those breakers need to be tripped before you work on either line.

On common neutrals the neutral only carries the difference, if line 1 carried 10 amps and line 2 carried 6 amps only 4 amps runs through neutral, if they both carried 20 amps 0 is on neutral ,  the hots are on opposte phases so they cancel each other if they are on the same phase well the house might burn down since 40 amps could then go through the neutral wire melting it.

The reason they used aluminum wire and rationed copper in the last half of the 1960's was the Vietnam war. I used to own a house completely wired with aluminum biult in 1967.
