OPPO BDP 103/105, sound quality???

Yes to the Oppo 105 but also to the Cambridge Audio 752BD.  Same Mediatek(OEM supplier) chipset as the Oppo and not a rebranded Oppo.

I have the previous generation 751BD and am very happy with the build quality and performance.

I'm a 105 owner but prefer my Rega DAC for CD playback (fed by the 105). SACD and Bluray sound good.

Make it easy on yourself, and avoid regret by just buying the Oppo. You will not be disappointed! The 103D goes for about $600, and the 105D about $1,400. The difference that I see is that the 105D has balanced outputs.

I understand the difference between the 103 and 105 is more than just balanced outputs.  If OP is sure to use only HDMI output, then a 103 might the obvious economic choice; if analog output is a possibility, then a 105.  Even if OP thinks use will be HDMI, a 105 provides flexibility for future analog use.

I was also thinking of a 103 or 105 to replace my Sony SCD777ES SACD player which is now a boat anchor.  I would be running the player through the dac in my Parasound integrated amp(ESS Sabre dac) using the coaxial digital out and use the analog section of the player for SACD only.  Do you think I can get away with using the 103 instead of the 105 in my particular case?
