Hi Glenn,
Yes, I would strongly recommend doing that. The one minute figure, though, was just a guess based on my experience with other high powered solid state amps. I suppose that a good way of determining how much time to allow would be to play some music at a VERY low volume level, then turn off the amp and see how long the music continues to play for. It would probably be a good idea to make that determination for going into standby mode as well as for going into "off" mode.
What makes all of this particularly important with your equipment is that your amp is capable of delivering enormous amounts of power (in the vicinity of 1000 watts) into the 2.5 to 3 ohm impedance the speakers have throughout the mid-range region. So even a very brief turn-off transient from the upstream components, applied to the input of the amp while it is still powered up internally, could very conceivably put your speakers in jeopardy.
Best regards,
