Hello. Here's my setup. Panasonic 42PX80. Sony PS3. Sky+ (not HD) I'm looking for a AV Receiver cheap or second hand to eventually add a 3.1 or 5.1 speaker setup to. The problem i'm having is i am confused about this HD Audio stuff. I realise that my PS3 can decode HD Audio and send it to a receiver. I also realise that is upscales video on board. I currently have it HDMI'd to the plasma. Here's my problem. I would like the setup to be as future proof as possible but don't need a receiver with onboard upscaling (PS3 does it already). I would like however one that can accept the HD Audio decoded on the PS3. What is it i am looking for in the technical specification of the Av Recievers that specifies it can accept and use the decoded HD Audio tracks. I didn't realise until recently that not all HDMI's transfer audio as well as video, however with the PS3 only having the HDMI to transfer HD Audio (is this correct??) am i out of options other than to go for a receiver with HDMI audio compatibility?? (am i making any sense???) To keep my budet down i am looking at older amps and second hand ones, any suggestions would be great. Budget £150 -£200 Thank you.
