As a general rule, even in my pre-1050 days (motorized volume knob with a dot), I would lower the volume level to less than loud (on the 1050, around 25 or so). That way, there was no jolt to my system regardless of what I was playing.

The other option would be to set your macro up to mute the receiver on start-up. Then, if you so choose, you can check the volume and change it to your preference. Or, you could be real sneaky and program the power off macro to lower the volume prior to shutting the system off. I've found that macros make many of the problems encountered with home audio fixable with a little creativity.
