Thank You Granmaster - the current wiring is FIOS DVR->HDMI->vsx90->HDMI->oled55bp(TV)->optical audio ->vsx90. Therefore, I cannot power off the vsx90. So how about a optical switch 1 in two out (one out to vsx90, the other to headphones)? With this, I could switch to headphones before power on the rest of the equipment. There is always a delay when vsx90 comes on, before I can mute or lower volume, so this would assure quiet when I turn on equipment (optical switch already set to headphones output). Does this sound like my best "logical" option?
