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?

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.

I have a PS 1000 power regenerated and sometimes I have my 14bsst 600 watt amp run into it. It never seem to suffer from dynamics but what technical people have said here is that the punch and dynamics have to be compromised to a degree. The 1000 can only handle up to 7 amps and up to 10 soft.. The Bryston pulls more. I couldn't tell a difference so I thought my wiring was a choke point. Oh thanks for the responses everyone. My 14b3 has just left Bryston and I'm making a good home for it here.
