Aside from the volume difference, and compression differences, which I understand, what is the reason (do you think) for the sonic differences between a 70s rock album and today? What I hear: Much more bass today Lots more stereo material - sounds much wider today Todays music is MUCH brighter. Drums are snappy, etc. Is it that with digital, you can record more low end? Is is purely stylistic? i.e., no one back then would have wanted a sound like today Is it related to the need to put on vinyl? Is it that technology today makes these things easy to do? In testing my monitors, when you a/b a modern rock track against a classic rock track, the sound is SOOOO different. The classic rock tracks sound small and dull by comparison.
