I said that there is material out there with 30db range. I also said most modern music does not have the range that you find in a lot of movies.
"From looking at some very old recordings (vinyl restoration) on a DAW, the largest dynamic range I've ever seen is around 40 dB."
Folks who listen to classical (and some jazz) music will find 30 dB and greater dynamic range is not uncommon. Until (as I understand it) very recently there has been zero loudness war in teh classical field, and likely only very gentle compression, if any, of the original tapes.
Pop music has (almost) always, at least since the 60s, been compressed for effect. A bit of output bus compression can sound very good indeed, without damaging the overall sound of the recording. The huge slamming that gets done too much today renders recordings that I cannot listen to loud. Many sound fine to me at low to moderate levels, but are hugely fatiguing to my ears, and just "sound wrong" if I want to hear them at anywhere near rock-approved levels.
On another topic, WRT power compression in speakers, IDK how you can fix it with amp power. If I have 3 dB of compression at, say 100 dB, I know I'll need more than 3 dB (double the power) of boost to fully overcome that compression, because the power compression gets worse and worse as you get louder and louder. If I turn up the volume control by say 4 dB, my should-be 100 dB sounds are at 100 dB, but the average (let's say it was at 80, for a 20 dB dynamic range) is also 3 or 4 dB louder, so I still don't have the dynamic range. Just louder more compressed sound, at say 84 to 100 dBinstead of 80 to 97 dB. Without something like a multichannel expander precisely tailored to one's speakers' actual input voltage versus output curve, the added power can only get you louder, but but cannot supply the missing dynamic range, as I understand it.
