I remember old carbureted engines that had a manual choke and had trouble starting on cold mornings. Amazing that they fixed this with modern technology.
Sad that some audio equipment should be still so poorly designed as to sound terrible until after an extended warm up. I have read that Class D is very difficult to do right and hard to build with reliable performance. A bit like Class AB is significantly more likely to have problems than Class A. Although Class AB is pretty good these days.
