Should I connect my OPPO BDP 105 to my PontisII?

What output are you using from the Oppo?  The HDMI output is for A/V only and doesn’t work for i2S if that’s what you’re using. 

I used the SPDiF out.  (Optical).  I do have the HDMI cable running to my TV.  Would that cause a problem?  If so, how to connect the OPPO to the TV optimally? 

Well, first I wouldn’t use an optical cable for to the Pontus as you’re introducing additional conversions to and from light transmission and it’s limited to 24/96.  Check the settings in the Oppo to make sure the digital outs are active and properly configured, and you also may want to try a 1m wire SPDIF digital cable in case the optical connection on either side is compromised (a regular analog RCA interconnect may work for this too just for trial purposes).  Here’s a decent cable that’s not too pricey if you need one, and you can easily return it if it doesn’t work…

Good luck!

Will do!  Thanks!!!  BTW.  The sound continues to get even better with the new streamer/DDC/DAC.  Full and rich.  Better definition, ect....
