When you use the 990's trigger to control the PF40, what's happening is the PF40 kills power to half of the unit's 12 outlets when the trigger isn't on and then turns the power on to those outlets when the trigger comes on. It's sort of like a wall outlet that is controlled by a light switch to operate a floor lamp or table lamp. You would turn the 755, M200's, and turntable on manually the first time, and then they'd just stay in that "on" state all the time - they'll simply turn off when the power is cut to them and come back on when the power comes back. This is how my 7500 and M200's work with my PF60. The 990, DVD-A/SACD changer, SoundBridge, HD-DVR, Sirius tuner, and probably the HK CD changer would all be plugged into the always-on outlets and behave just as they do now.
