Q#1 How would you be connecting the cd player. If you are using coax or optical from the cd player to the receiver there will be no difference in sound, the dacs of the receiver would be handling the conversion.

Q#2. I think if you are wanting a dedicated cd player you could do better for the money than those you mention.

Q#3. No !

Q#4. I have no idea, but I seriously doubt that would be the case.
