There are res formats Stan as I'm sure you are aware.

I don't think any orchestral music has that kind of dynamic range anyway, not whilst playing, so I fail to see what dynamic range has to do with anything?

If you'd have said peak to average ratio of volume of sound I think it would have made more sense. If you look back at that screen shot it shows about 25db peaks (not being silly & giving the 137Db peak figure) over the average content.
