Class A preamp or Class A amp



Hi, what is the best and most efficent way to bias an audio signal? Class A preamp with a class B amp or vice versa? Thanks

Transistors need enough bias current to 'Wake them up' into their linear operating range. Higher bias levels will generate more heat and use more electricity. Since heat is the enemy of long life a cooler design may be wise.
