I was told that it has better Video and Audio conversion. Also the 103 will up convert to 4K. I have a 93 in my cart on eBay but I have to buy a remote. It Isi $216. If I can get a 103 for about $250 then I will. Other wise it will be a 93. I wouldn't mind an 83 or 203 but the process are outrageous for both. I would think the 83 would be less than the 93 but not.
