My situation is different from that which came up on searching. I am debating between the 805 and 876. My system is only DirecTv HD receiver and Samy BD1500 going through the reciever to a Sony Pearl. I aslo have a XA-2 for rare SD occaisions. I also use outboard amps (Parasound and Accurus). Would I gain anything from the 876? I already have the Reon chip in the XA-2 for SD DVD. Thoughts?
