Okay so first of all I wanted to say that I don't have preconceived notions already behind the science behind audio. I just had a question. I want to be educated on this matter. I feel like my system sounds better at night. I live on a busy intersection in downtown Toronto, and I get the feeling that at night, my music system sounds remarkably better. Is this possible? Is this a thing science can explain? Or is it placebo? For the record, I have a high end stereo system, not a headphone setup. I'd like to get one, but anyway that's irrelevant to my question. What do you guys think? Can the time of day effect how my system sounds? My theory is that it sounds better at night because there's less people in my local neighbourhood drawing power. And thus the power that gets sent to my system is cleaner. However, I don't know anything about how power works, perhaps I'm only hearing a placebo. I'd just like some answers.
