"... record live sounds, one finds there is a huge dynamic range present even in everyday sounds. "
As I said, no argument. I believe a crest factor of 40dB has been documented, somewhere, for live music of some reasonable sort. (Actually I think a solo piano has a pretty huge crest factor.)
I'm just pointing out that (if you believe the papers in refereed journals to be accurate) it's rare to find a crest factor greater that 14dB on available commercial recordings, and extremely rare to find one greater than 20dB.
I certainly agree that this may be one of the things that make any (commercial) recording not quite as real as the live event. I have no difficulty imagining that exotic recordings can be made to exhibit correctly very large crest factors, and that such recordings will be an eye-opener to most audiophiles.
Incidentally, though I don't know the numbers offhand, I think well-done tape can have a much lower noise floor that you quote above. I've been involved in the last few years with The Tape Project, though not as a principal - I'll post the link, but invite the moderators to remove it and/or this post if I am exceeding the bounds. There is a forum, where discussion of noise floor limitations would be appropriate. There is also a Tape Asylum here where such discussions would be useful.
