I agree with noromance…. 110v clean power. Sometimes power can be less of a demand on power companies in the mornings. During the day the power can get more loads. Early in the morning, I found music sounds much better as well. During the day sometimes I felt like there was a flaw in my system.
Mood
Last night, listening before I went to bed, I was convinced there was something radically wrong with my system. Nothing sounded good. This morning I decided to play something I was sure would sound good. All of a sudden my mood picked up. Now everything I heard after that was reference sound quality.
I wonder if anyone else has had that kind of mood swing from one day to the next.
