From the number of damaged speakers we get in for service, I dont think your idea works in practice. And Im lost when you say "know when a recording comes into its own at a particualr power level". I assume you mean that you should be able to hear when it begins to distort? Gosh I wish you were right becasue if this were true I would never get a blown speaker/driver in for service!
I’m also not clear on this idea that Recordings have a favored or preferred power level (assume you mean playback SPL). Playback systems systems do have a maximum power level, but Im not sure they have a preferred or even minimum playback SPL we could all agree on. QUADS were notorius for having a very limited max power level and limited dynamic range so perhaps your hearing is oriented around this? (Billy Woodman from ATC loved loved loved quads for their extreme definition).
Recording systems also have "preferred" input gain settings as well but even this is up for debate in practice. There is a well known story of the Beatles arguing with the Abbey Road Engineers that a distorted input signal (exceeding the preferred input gain of the system) was NOT a mistake.
