I need to burn in a DAC, connected directly to a poweramp. Here is my (probably dumb) question.
I am thinking that if I play the DAC with the poweramp off, there will be voltage on the outputs, but no (or little) current flowing. Therefore, to burn in the DAC the poweramp needs to be on. Is this a crazy idea?
No. The input impedance of the amp, and hence the amount of current that it draws, is most likely determined primarily by resistors that are connected to its inputs. Those resistors will draw the same amount of current regardless of whether or not the amp is turned on.
