There are currently only two ways to pass the new uncompressed audio(example: DTS-MA/TrueHD)from HD and Blue Ray, and this is through HDMI or Analogue. I went on a quest to find a new AVR with HDMI. I researched Denon, Yamaha, Pioneer Elite, Onkyo, Marantz, NAD, etc... through reading many hours of dedicated threads on AVS forums. I just can't find the AVR that does it all real well, maybe next generation.
I decided to keep my 1070, at least for now. So, once I get a new HD player I will exclusively use the analogue inputs on the 1070 and hope it works well. I’ve used the analogue inputs with my SD Denon DVD-2200 but not completely satisfied. I'm hoping a player like the Toshiba XA2 will be more satisfying,(if anyone has the XA2 please let me know your analogue settings for the player and 1070). I was leaning toward the new Samsung BD5000 combo player, but currently the audio is not up to snuff, even the analogue section.
Nice comparison of high definition optical disc formats
