Guido, FWIW I think that your analysis of the value of a collection of audio equipment sort of focus's on its ability to reproduce (and for you to hear when the recording engineer puts his mikes near the sound board) what is going on when you sit next to the piano, just as a conductor hears from the podium, but the reality is that few of us ever do that. Our reality is quite different.
We are usually quite some distance from the piano where these low level sounds, some of which are mechanical and are not in the score at all :-) are lost, but where the dynamics and the appropriate volume rules our appreciation for what sounds like a live piano. But, to get that thru the recording and thru our audio systems it is going to get compressed. And it is that compression that really robs the music of any real sense of liveness. Ultimately you still have suspend your sense of reality and just 'pretend' that it is live.
You might be amused, but I work in a room adjacent to my audio room (accross am open hall way) and I often get caught up more in piano music playing when I'm there than sitting in the sweet spot. :-)
