As I've stated in print, the basic differences in sound between analog and 
digital are

The "warmth" of analog is hum.  Remove the hum and a good recording will 
sound like weak digital.

Digital offers greater dynamic range an, most notably, the absence of wow 
and flutter.

Enter the various methods of reducing and removing wow and flutter.

We built he best with the bricks we had.  Better bricks became available so 
we use those.  There are some who prefer the recordings built with older 
bricks.  There are those who use various properties of the new bricks to to 
enhance the sound of the older recordings.  And those who believe they are 
doing so but are not, in particular, introducing the loss of ambience that 
occurs using uninformed use of some of the declicking and other "clean-up"

My old tech Jeremy used to say "Iron is the sound of analog..."
