You might try an Oppo BDP-105 directly to amps first. Updates in technology tend to lead to early obsolescence of processors. I bought a used Cary Cinema 11a for DSD via HDMI and speaker management. Stereo from the C11a goes through a Parasound JC-2 BP analog preamp. Before I installed the Cary, the Oppo filled its role -- I was obsessed about getting surround DSD from a Sony XA5400ES, perhaps foolishly, but I was able to buy the C11a for about $1200. Anthem processors don't process DSD via HDMI.
