Whatever we say or do the dynamic range is still that most challenge aspect of audio. A dynamic range is a derivative from dynamic capacity of our sources, dynamic capacity of our amplification, quality of our electricity and dynamic capacity of our acoustic systems (implying speakers + room).

Everything is simple. We use a higher dynamic range frond ends, we use higher dynamic range amplification, we fight our endlessly-losing battles with electricity and we use acoustic system which convert one Watt of electrical energy into one Watt of acoustical energy with near a hundred percent of efficiency. Still the mysteries about artificially-produced within out playbacks dynamic range exists and the dynamic range problem is the most common.

How come that some of our frond-ends with tremendous dynamic range subjectively sound less dynamic than the frond ends with 70dB of dynamic range? How comes that some speaker manufacturers using the identical technologies are able to demonstrate such a drastic distinctions in their speakers dynamic ranges? What is responsible for acceleration of dynamic range in our playbacks? What are the true rules of dynamic ranges projected to the listening volume? Why “live” sound has no such a listening property as “dynamic range”? Is dynamic range the final category or the dynamic range it's just simplified version of something that we invented for ourselves in order do not look deeper at the most prominent things? Where is that bottleneck of dynamic range in audio? What can we do about it? Is dynamic range static or dynamic parameter? If a person recognizes existence or multitude of stratified dynamic sub-ranges then how those sub-ranges associated with everything else? What characteristics are responsible for masking out, improving or challenging the dynamic range characteristics? And so on and so on….

I can throw many other questions but still the subject of dynamic range is the more talked and at the same time it is the last subject practically understood and one of the worst successfully implemented audio requirement.
