I don't know about HDMI sounding better than analog. It would really depend on the DAC's used.
If you had a $500 receiver, then it's a safe bet that HDMI is probably the better way to go vs analog, as the analog inputs aren't likely to be that great.
If you have a higher end receiver or a controller then there is a chance the analog inputs could sound "better" than HDMI. It would depend on what you think sounds better to your ears and again, the quality of the DAC's in the 83 in comparison to your receiver's.
The 83 has very good DAC's in it and the 83SE are spec'ed even better.
Your question will be easier to address when there are decent reviews of the SE available.

It's all speculation for now.
