Sony XA9000ES mods?


Who does the best mods on these solid beasts?
I am finally moving up to top line Wadia, EMM or Esoteric
and am considering modding the Sony instead of selling it.

So, if I'm not looking for a mod in the near future, would a XA9000ES offer noticeable 2 channel sonic advantage over my DVP-S9000ES (in video-off mode)? I've never heard the XA. Anyone compared the two?

I'm sorry but I confused the two Sony models. I friend of mine extensively modified his DVP9000. He claims that with mods to clock, power, and analog section, this piece gets reasonably close to his modded 777ES. One good thing about the DVP9000 is that used units can be acquired cheaply for sparing purposes.
