Time of Day for best Sound

I've always felt my system sounded best at night, but the last couple months, it seems to me that my system is sounding better during the daytime even on a Saturday.

Has anyone belonging to the "My system sounds better certain times of the day" club noticed this change?

Not a big deal but I find it curious. And theres no need to debate the reality of the general idea, just wondering if someone else feels this has happened.


For the record I have been using a dedicated 20 Amp feed.


Weekend evening time,  settled in with a very peaty premium Islay Scotch . LAGAVULIN 16/ year old is my usual go-to to sip







I've definitely heard differences put haven't been able to establish a pattern to it. Although it seems random, I'm  sure it's not. Night isn't always the best. I live in a condo and most folks are getting home from work when the amp gets fired up. Then I wonder how much the electric trains across the street effect the sound. I say this because my phone drops calls almost every time a train rolls by.......
