Pavarotti, yes. Orbison close to a mic, nope. There isn't a compressor on earth that can do what intelligent manual gain riding with full knowledge of the score can do. Compressors are always reactive, not anticipative and interpretive. Even with today's "look ahead" processing they are still reactive, dumb devices that make "decisions" based on fixed analysis of the envelope, but have no understanding of the musical message or emotional content, and therefore are often in error. Now, just as a sanity check (mine?), I'm not talking about processing a vocal track here. That's a job done just fine with the right compressor and settings. I'm talking about controlling dynamics of a full mix of an entire movement or movements. Sort of agreed. There is a point to recording without dynamics processing, but it's definitely not for every recording, or even very many. Proper application of technology is always the best way, and to do that one must have the entire picture and purpose in mind.
