My Marantz works this way and it annoys the shit out of me. If (and it's a big if) there's a time that you want to play both the speakers and headphones, then that's the time when you should have to hit the button.Did I ever tell y’all about the night I spun the record, plugged the senns in, forgot to turn the speakers off (a truly baffling issue with the nad) and cranked it up about half way through waking up the house at like 2 in the morning to Drops of Jupiter?
