Jason,
the manual suggests not to leave the amps if the source component usually the preamp) is turned off. Otherwise, it could pick up noise from the floating input and overheats the unit. And indeed, if it is left on, the unit actually gets quite warm.
So, is it okay or advantageous to leave the amp on all the time?
Or if i should keep the source component on if i really want the amp on all the time? Is the source component in standby mode fine?
