Caps probably have little to do with it, but I encourage you to get a temp sensor to validate your observations.
Bias is set generally to get the best balance of low idle power and lowest distortion. Class A is, as I recall, the opposite, and attempts to maintain high idle power. The differences you are feeling, if real, are due to the transistors, not caps.
Best,
