The latest Blu-Ray players (I have the Sony 550) have introduced some new audio formats. I am still using a previous generation Arcam receiver, which only allows video pass-through on the HDMI connections, and cannot decode the new formats.
Are the audio formats finalised, or will there still be modifications in the near future? Any recommendation on new units that can handle the new formats? How would one get the best sound quality: via the HDMI, optical or RCA (letting the Sony do the decoding) ?
Rest of the system is the Gallo Ref Front/center/sides/sub and a Sony VPW50.
Thanks for any guidance.
