I've got an Onkyo TX-SR703 with 7.1 analog inputs that I'm perfectly happy with. I'd prefer not to have to upgrade it just yet. So, I’m patiently waiting for confirmation on whether the S550 does in fact internally decode DTS-MA and outputs this to analog 7.1ch outputs. After having read many of the posts in this forum relating to this topic, I'm betting the answer is going to be "no". On the plus side however, my understanding is the player does internally decode Dolby TruHD and outputs this via analog.
My question is: How important is it really for people in my situation (ie Receiver with no HDMI....but with 7.1 analog inputs) to have a player that internally decodes and outputs 7.1 via analog "both" Dolby TruHD and DTS-MA? It seems to me...on the surface anyway...that having a player that will internally decode/output 7.1 via analog for only Dolby TruHD might be sufficient...albeit not ideal! At least I'd have one option for getting some version of "HD" audio. Are there many blu-ray titles that "only" have an option for DTS-MA (and not Dolby TruHD)? If so, I guess having a player that "also" internally decodes/outputs via analog DTS-MA would be crucial for people in my situation. If not, seems like the S550 might be an “okay” option for people in my situation.
