Best audio settings for my OPPO 105D

Hi everyone ,Purchased a OPPO 105D 2Years ago and totally love it ,the sound is wonderful and have just been using it with the factory settings ,Am wondering if it can be any better by adjusting the Audio settings ,I'm no tech expert and don't really understand the various different settings available in the settings menu , My System is stereo , I have a Denon PMA-655R AMP and my Speakers are a Pair of Infinity Floor Speakers ,I Listen to Music via CDs and a WD external HD with Wav audio Files and also Videos ,OPPO is connected to TV via HDMI ,AMP is connected to OPPO via Good Quality RCA Plugs , Hopefully this is enough Information to Help with any Ideas you good folks May Have , Thanks in advance , Cheers Adrian.

 

pure audio mode and fixed volume setting.

 

I would add set it to SACD, then, whenever (or if) you play one, it'll automatically read the SACD layer, but won't affect your enjoyment of CD

 

Use OPPO's XLR out if possible.
Apparently better SNR.
Turn HDMI Audio OFF when listening to analog stereo.
Ensure Audio DRC is OFF
