Maybe - all things characteristics change with changes in temperature, especially metals. It would be interesting to measure electrical characteristics of interconnects before and after use.
Do Interconnects need to "warm up"?
My system is left on most of the time and sometimes on standby. I noticed that when I first start to listen the sound is a bit bright. All of my IC's are balanced and single ended Silver Streaks, the components are Krell. It seems to take almost a half hour before the system seems to calm down where it then sounds smooth and sweet. So I was wondering, is it possible that IC's may need to warm up as some equipment does - your thoughts? Thanks!
