I hope you can help .... with hooking up SACD/DVDA/BluRay player .... when one has an option to use HDMI vs Analog 7.1 connection .... which one will sound best???
Planning to use mostly for SACDs and DVDA surround music.
for example this unit

That depends on your speakers, room, and tastes.
Many swear by Audyssey XT32 and dynamic equalization.
I use an BDP-105D as my preamp and it suits me fine.
Cambridge Audio Azur is built on an Oppo platform with some changes to the analog stage.
At that price you might want to consider the Oppo 105 and 105D.
Folks can tell you their preferences and why but they cannot tell you which "sounds best" because that is a subjective evaluation and we are not you
