I have a configuration question regarding this TV as I upgrade from a component-video projector system to a big-format LED TV and HDMI A/V sources.
I am contemplating using the 90-incher as an HDMI input switch rather than needing an AV Processor like the Marantz 7005/7007 to connect an HDMI Blu-ray player, Mac-Mini w/HDMI, cable box w/HDMI, maybe Roku, etc.. The TV has plenty of HDMI inputs from which to choose.
I already have a Parasound 7100 surround processor for my 7.1 amps/speakers system. But, it only has component video switching and won't do HDMI. As I looked at the 90LE745U connections, I see that it has an optical audio output that could route all the digital audio to the input of the Parasound 7100 and let it do the surround processing, yet the TV could serve as the HDMI input switcher. By using the Sharp 90's remote to select a desired input device, it would allow the TV remote and on-screen input selections to make operation obvious to novice users without lots of instructions on how to use a Marantz (or other) AV Processor as an intermediary.
The goal is simplification for my family, but my concern is digital audio pass-through quality as it is routed through the Sharp. Is using the Parasound via the Sharp's optical audio output a viable solution? Will there be any "trans-coding" or stripping of surround formats or other degradation of the digital audio inside the HDMI to Optical conversion done by the Sharp?
What can the experts here tell me about my idea?
