I currently have my iMac connected to my Sony Bravia TV via a mini display port adaptor...This works fine, and I also swap it over for my MBP and MBA from time to time. Question is, I have just installed a new Onkyo cinema system, and have plugged my devices into that rather than the TV itself...The only device using a TV port is my ATV, but I may move that over too. Has anybody plugged the HDMI feed into an Onkyo? If so, hows the quality of the picture and sound? I currently have my 3D Blu-Ray player, HDD recorder attached to HDMI1 and HDMI2 respectively...I'm guessing that the ATV could be plugged into either of the remaining ports, and the same goes for my Macs?
