I do understand that the DAC chip is just one part of the equation, which is why Oppo continues to modify its designs and why additional modifications can help quite a lot. (Don't Ayre and Theta use the same platform and chip set that is in the Oppo?) And one nice feature of the Oppo is that you can use the balanced outputs for FL and FR in a multichannel setup. The Marantz (and the Denon?) does not allow this. The Marantz also has numerous ergonomic problems (the interminable load times for Blu Ray among them.)
Last but not least, I know what my ears tell me. I know that time plays tricks on one's perceptions so I won't swear to it; perhaps I am just drinking the Kool Aid
But my modded 105 seems to be as warm and engaging, yet still just as detailed, as the UD9004, perhaps even better. And the 105 plays all discs flawlessly, zooms as needed to fill my screen, does not occasionally confuse 2ch and MCH playback, does not occasionally boost the rear speaker volumes without warning. With comparable audio quality and hands down superior ergonomics, the 105 is a clear winner in my book.
Okay, give me that Kool Aid!
If you read my other posts you will know I tend to exaggerate a bit.
Your Oppo is a fine machine. Even the Absolute Sound, a magazine i have
been getting for free for several years now, usually heavy on analog equipment, has
a superlative article on the 105.
It is good to know the 2009 UD9004/A1C/MVP881 still keep their ground.
I was also very impressed with the Oppo DV-980H at the time, about the
finest piece of equipment i had seen out of the Middle Kingdom in my time.
