OPPO 980 h dvd mod?

Just got the Oppo 980h. It sounds incredible.
I don't think I will want to spend more than what this costs, on a player ever again.
How much better is the mod?
I can't believe it can get better than this, especially in a chassis this light and thin!
Is the mod worth the extra expenditure?
Where do I get it modded and how much is it?
