Oppo 83 SE wich would be best for my system vs 83

Hi

I would like to know if anyone can share with me, if the SE will be a noticable differece, or marginal over the 83.

I have a Arcam 300 reciever, BDP400 Mirage Sub, Allisons fronts , center and rear speakers. Above average. I'm using the Cambriddge -Azur 540D DVD player, actually very good picture and sound is good, not excellent.( playes NTS & Pal)

I don't need to play SACD or CD, just DVD.
and I want to use the Audio outs to the Arcam.

Question: Will I really notice the Audio sound worth spending the extra $400 or so over the 83R?

I actually not trying to save the $400, just want to know if this makes quality audio sence?

Thanks
peter
