Well, the Sony is still less expensive.

No, honestly. You want a home CDP, you've already got a portable player, so you might as well get an inexpensive home CDP like the Denon.
Since you also have a headphone amp, you don't even need a CDP with a headphone jack. Get one with an optical out and you can use it as a transport like thomas suggests.
At the end, it all depends on what you'd be happier with.
Just imagine yourself with a new portable and with a new home CDP, and then buy what's gonna make you happier.
(Sorry for changing my mind, but at first it seemed like you preferred a portable and some guys here had some very convincing arguments)
