Re; Dynamics, Class D vs tubes…

Class D amplification vs tube amplification, which is likely to be more dynamic at lower volume playback?   Assuming speakers that are more difficult to drive than average.  Let’s say, 4 ohms dipping to 3.2 ohms and running about 85 db efficient.

I drive my KEF Reference 1 speakers with an old Krell KSA-80 class A amp, rated at 80-Watts into 8-Ohms, 160 into 4 and 320 into 2.  The results are stunning, but I have not really compared amplifiers.  The speakers were demonstrated with McIntosh but unfortunately I took little notice of the power source - the speakers were the best I have heard at any price.  The KEF specs say 50 to 200 Watts.  I would err on the high side!

I really don't understand why the amplifier should affect low level dynamics, unless the amplifier compresses the output which surely would be at high volume?  A "straight wire with gain" would leave dynamics unchanged?
