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 Tom
