I am looking to do something similar, but just for Home Theater, not so much for music. So I purchased an Oppo-UDP-203 and have it currently connected to my Marrantz AV7005. However the Marrantz does not support 4K UHD, but then neither does my TV. I am looking at getting a new Sony 65" 4K TV, and then at the point should I:
1. connect Oppo (HDMI 2.0) directly to TV
2. Eliminate Marrantz and go analog direct to my Parrasound 5 channel amp.
Problem is I have two other devices (Apple TV and Telus box for TV) and only one HDMI input on Oppo. I could get rid of the Apple as Telus device is pretty much doing everything Apple does (movies, Netflix Youtube etc), but my whole house and phones are Apple so displaying pics and other music streaming via Apple is easy and convenient at times, though I must say I don;t do that often.
I am thinking all those devices should go directly to the TV, and have the TV do the switching and then ARC or digital out from TV back to the Oppo. What do you think??
Or are there any preamp/sourround processors only (no video processing) that I should be looking at. Anthem AV60 is one option as I believe the Video is basically pass through, but is spending $3k for HDMI switching and room correction really worth it?
