SQ of Oppo 105 v Anthem D2 or D2V

Currently, an Oppo 105 is my only source for surround. Its analog stereo output goes to a Parasound JC-2 BP, surrounds directly to amps. My Sony XA5400ES does surround only via HDMI. I wonder if surround SQ would be improved if I connected the Oppo and Sony to an Anthem D2 or D2V.

Stereo is handled by an Ayre C-5xeMP and Thorens TD 124 with Ortofon SME 30H cartridge through a JC-3.

Has anyone compared the Oppo 105 and Anthem D2 series sounds?
