Sony XA9000ES mods?

AFAIK, VSE primarily strokes the analog section. RAM works over clock and power supplies into the transport section.

A 9000ES modded by Reference Audio Mods or VSE should get very close to the others.

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.
