Difference Between Sony BDP-CX7000ES & BDP-CX960 Changers?

[AV_Integrated]

I am looking for a single list of what the significant differences are between the ES series and standard 400 disc changer from Sony other than the obvious back plane changes (analogs/serial) and the aluminum chassis.

I have a number of installations where I am looking to put in 400 disc changers, but the price delta is significant enough between the two that I really do need to know what the differences are.

I will not use an Escient - and never will if I can avoid it. In fact, if Sony fixes their interface a bit more there is no reason that it should not perform almost as nicely as the Escient does by itself. It's adequate enough as it is.

I did look through several pages of the official thread, but didn't see the specific differences concisely listed and would like to hit just the differences as people know them to be.

Thanks!
