Help - My systems sound changes around 9.30pm
Wondered if anyone could help me, when im using my system i notice a distinct change in sound around 9.30pm, the sound gets fuller and deeper, (richer ?),
problem is it doesnt sound right, pre 9.30pm the sound is great nicely balanced and very enjoyable. When the change comes it has the effect of stopping me whanting to listen as its not right. It doesnt make any difference if ive been using it all day or just a few hours.
Only thing I can think of is the local heavy industry (steel works) shuts down at 9.30ish as they only run 2 shifts.
Question is how do i find out whats causing it ?.
