Because if the answer is Yes, then I'd say the 105 is worth it. If the answer is No, then I'm just going to move on from it and live with what I have. I'm very interested in the DAC quality of the 105 for music playback specifically.
I have wondered the exact same things. The Onkyo manual is not definitive, the question mostly is whether the Onkyo volume control works when using analog inputs. My guess is that it does, so some minimal processing would likely be in play.
Now, for 2 channel music, using the Carver amp, that should give you no processing other than the Oppo's.
The only way you're going to really know is to try the 105, get it's processing set up well and compare the Carver to the Onkyo with 2 channel source.
You might want to use Audyssey for surround sources as well....
The Onkyo with pure audio may give you the least processing of most any other receiver. To do better would probably mean independent amplifiers for all channels, which is why I suggested using Onkyo for multi-channel and Carver for 2 channel.
Hope this is worth something, if you do go forward with this PLEASE come back with results - it is an interesting question.
