MP your idea about humidity goes against the jist of the other postings. Humidity goes up at night as the temperature falls closer to the dew point. Everyone is saying there systems improve (at night with higher relative humidities) so a dehumidifier would go the other way. If anything you need to add a humidifier. Don't think so....
System sounds better at night?
I have noticed that my system sounds MUCH better at night, after about 10pm than at any other time of day. It is clearer, more open and transparent, with a blacker background. Another audiophile told me that this is not real, it's just that there is less noise in the household at night. I disagree in that what I hear (or don't hear) is not simply due to less ambient noise but rather cleaner sound. Will power line conditioners simulate these effects during the day? Has anyone else noticed this and what is the most effective way to get better sound during the daytime? Serious responses only, please.
