Amplifier warm up

I was plalying Boz Scaggs, "Silk Degrees" LP.  After side one, I ate dinner.  One hour later I played side 2.  The second side sounded clearer, more vibrant with better sound stage. I have a Parasound P6 preamp and Parasound Halo A21+ amp.  Is it possible that an hour of warm up improved performance?

So if I’m using little fans to manage the temperature of my SS amp, does that mean it’s not warming up sufficiently to play at its fullest potential?

I am totally off grid(closest power pole is 2miles away) ,I have solar ,generator backup and lithium4 batteries . I do power my hybrid down and it takes a solid hour min, to get my system to open up. I run class D in my video room that is always in standby mode .

Yes.

Temperature changes will change the biases in transistors and hence make differences.

It is almost like an ICE engine.  It runs better when it is warm.

I leave mine on 24/7 unless there is a serious threat like a storm.
