If there is (which of course there is) a percivable difference in sound quality between for example the new OPUS and the MP3 codec and their coding technology, what for example could that be?

Does the listening material have impact on the percived difference between the codecs, example if you are listening to speech or music?

I also presume that the percived difference also is different between people and target groups. What is your opinion about this?

Yes, especially when the codecs use different technology (transform vs. CELP).

Yes, experienced listeners often perceive differences differently (and perceive differences more easily) than naive listeners who have never done a listening test.
