The example of the glass clinking is a good one. Take for example Waltz for Debby, where the glasses and chatter can be easily heard in the background. For me, on my replay, the background information is integral to the event and does not distract from the performance. As Peter has mentioned in this thread, my mind can wander in the recording from the musicians to the audience and back again with out feeling distracted or annoyed. I believe that with greater resolution this relationship is maintained, whereas with greater detail it is disturbed.
This sums it up nicely for me, dcathro. The mind is free to wander at will, focusing on the particular aspect of the experience that captures its attention at the moment. When it is all about details or images, the mind is stuck, and removed far away from the music, the gestalt, the intent.
When it comes to music, resolution, the system's ability to resolve the information on the recording, is far more than pixel count. A system must contend with scale, dynamics, tone, balance, weight, relationships, so much more. When all is in order, the system is very resolving, and if the recording is good, the experience is more complete. That leads to believability, involvement, enjoyment.
Counting pixels is not what happens in the concert hall, and it is the last thing I want to do in my listening room. Even when describing the quality of up TVs picture presentation, there is much more to it than pixel count. Micro plasma TV actually has a pretty small pixel count, but the image is quite resolving and realistic looking to me. It does not have a super sharp, and enhanced image edges that distract from what is happening on the screen.
This is the distinction I read from the opening post.
