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?

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.
