Summary: I own an OPPO BDP-83, not the 83SE, but the latter unit differs only in that it allegedly has a higher quality analog output circuit. Otherwise, the two are identical. If you connect to a receiver via HDMI or the audio via digital out, you don't need the higher priced SE model.
Summary: DO NOT GET IT YET! I got it on the basis of one review and my previous experience with an upscaling OPPO - excellent unit. OPPO has had this unit out for evaluation and review to Early Adopters. I got one of the first for regular consumer use. It has many defects.
