Albert...you get the new ESS DAC chipsets and upgraded power supplies which were the two weak points of the base BDP-83 player in terms of audio playback. Click on the link I posted in my first comment above (i'll include it again): http://www.oppodigital.com/blu-ray-bdp-83SE/blu-ray-BDP-83SE-Features.aspx...
There are four tabs:
(1) "Features/Specs" which describes the SE in detail
(2) "Comparison" which compares the SE to the base model
(3) "Images" close up pics of the SE front and back
(4) "Upgrade Option" a description of the upgrade for base model owners.
Again as has been mentioned before, the upgrade to SE only impacts the audio performance through analog outputs (does not impact performance if you are going to be using HDMI output). Hope this helps.
