There should be no differences when other codecs are used, ala Dolby and DTS as all 0's and 1's as you say are buffered in AVR before decoding to PCM and then re decoding to analog.
PCM signals are decoded straight to analog and are therefore more prone to jitter.
I completely agree and this is also my understanding of the technical background. But my question is: Why do I hear differences, when I am doing an A/B comparison between two players?
Can it be that this is a side effect of the video chip? Or something about the power supply?
I guess the people who design these players know, but nobody told us about this - also only a guess.
Well, it is some kind of miracle happening there. Personally I don't want to extend this topic any further and I take it as 'a difference between two different players' and it is OK for me. May be some time later, somebody will find out, why digital players can sound different, using digital connections. Currently, I don't have a clue.
I will test tomorrow HDMI 1 and 2 output, because there is a lot of fuzz here about it. This is also, IMO, an interesting topic.
