What "more" does the Oppo offer??? While I appreciate that you have experience with the Oppo, do you have personal experience with the ud5007?
I keep hearing Oppo on here, but nobody can seem to distinguish the benefits of the Oppo (other than -$100) over the Marantz ud5007. And just because you've owned Denon and Marantz in the past does not lend itself to this discussion. The Marantz ud5007 is NOTHING like the Marantz players of the past.
